How to Prevent Mold in HVAC Systems

How to Prevent Mold in HVAC Systems

HVAC systems are one of the greatest inventions of modern times; they make our homes livable in extreme weather. One of the ways the HVAC does this is by limiting air exchange between the inside of your home and the outside. The building envelope lets a house maintain a different temperature within itself than the temperature outside it.

This innovative system allows us to live a fairly consistent lifestyle regardless of prevailing weather conditions. But the system isn’t without its drawbacks. By limiting airflow between the home and the outdoors, the air inside your home is not easily diluted by fresh air from the outside. The result is that indoor air often accumulates more contaminants than outside air.

Data from the EPA shows that air pollutant levels inside the home can be 2-5 times as high as that found outside. These indoor pollutants often include asbestos, formaldehyde, or lead in paints and other construction materials; tobacco smoke; kitchen smoke; pesticides and toxic emissions from treated wood or similar items.

But by far, the biggest source of indoor air pollution is mold. That’s because the controlled climate of a modern home creates many hiding places where mold can grow. To thrive, mold needs dark, moist spaces low in oxygen. Your home’s HVAC system often meets these conditions, making it a favorite location for mold growth.

Is there mold inside your HVAC system?

If your home’s humidity level is above 60%, the chances that you might have mold in your home are high. This is especially if the high humidity issue is an ongoing problem. In addition to humidity, indoor temperatures above 60ºF also increase the possibility of mold. Below are some of the telltale signs of mold infestation in a home.

 

  • The air conditioning smells funny

Does the A/C smell funny every time you turn it on? Do you see dark fuzzy streaks on the air filter when you replace them? If your standalone air conditioning units are always damp and located in a dark place exposed to warm temperatures, they can breed mold.

  • Musty odors in the home

Mold has a characteristic odor caused by Mold Volatile Organic Compounds (MVOCs) released by mold. If your home has a musty smell that lingers even after cleaning the house, it could be because you have mold hiding in the HVAC.

  • Allergies that won’t go away

Chemicals released by mold can worsen existing respiratory issues. If a member of your household suffers from asthma or allergies and the symptoms flare up and refuse to subside, it could be due to mold spores in the home.

  • Strange fatigue

Constant tiredness is another sign that mold may interfere with your body’s functions. If you struggle to wake up in the morning despite having slept all night, it could be because mold is upsetting your body’s chemical balance and rhythm.

   

What to do if you have mold in your HVAC systems

The following steps will not only help you get rid of the mold inside your HVAC, but you will also prevent the problem from happening again.

1.    Get a mold remediation expert

The procedure for dealing with mold inside an HVAC system depends on the cause of the problem. Typically, you will want a solution that takes the entire HVAC into account. That’s because mold spores may be deposited in other parts of the HVAC where there is no mold. Treating the whole HVAC will prevent the recurrence of the problem.

2.    Get rid of dust inside the ductwork

In addition to the other listed factors, mold also needs food. The dust inside the HVAC ducts is what mold feeds on. If there is no dust in your HVAC ducts, there is little chance of mold growing in that space. You may not need to clean your ducts as often as you service the A/C, but this depends on how you use the system.

3.    Service the HVAC on a schedule

Change filters every three months or earlier; service the A/C unit at least once a year and check the condensate drain for leaks (this is a common leak location). Make sure the coils are also cleaned. If you hire a certified HVAC technician to service the HVAC, they will typically take care of all these.

4.    Monitor humidity

By simply altering one of the conditions – food, warm temperature, high humidity, and darkness – that mold needs to thrive, you make it harder for the fungus to grow in your home. Aim for indoor humidity of 40% or lower when humidity levels inside your home climb above 50%, the chances of mold growth increase exponentially.

Although mold can be deadly to human health when it grows inside a home, keeping it out of your home’s HVAC systems is not so difficult. All it takes is vigilance, along with the expertise of a reputable mold remediation company and an HVAC professional.

What Is Air Conditioning?

Air conditioning is a process in which the temperature within a room or building can be changed to suit your comfort levels. Air conditioning does this by removing warm air and replacing it with cool air, cooled down by mechanical equipment called an air conditioner or AC.

What Does An Air Conditioning System Do?

An air conditioning system maintains indoor temperatures that are cooler than outdoor temperatures. Typically, cooling occurs through a refrigeration cycle utilizing a compressor, condenser, expansion valve, evaporator, and heat exchanger. The compres­sor increases pressure on any gas that enters the unit. This additional pressure makes it more likely for the gas to condense into liquid form (i.e., water). The pressurized gas then enters the condenser where it’s cooled by a fan and other elements that dissipate heat. The condenser assembly is the only portion of an AC system that typically touches outside air, which may be hot or cold depending on the weather. Heat collected from the gas turns to water, and then drains away through a drip pan and eventually back into the ground via a drainage system such as a sump pit.

When warm air in your home meets this condensed gas in the evaporator coil (also referred to as an evaporative cooler), it absorbs some of that heat energy before exiting your home through vents or return ducts.

The refrigerant cycle continues when this condensed liquid is sent to an expansion device where its pressure really drops down, causing it to become a gas once again. The AC heat exchanger has cool refrigerant flowing through it, while hot air from your home passes over the outside of the device. This causes the chilled liquid inside to evaporate and absorb heat from your indoor air before returning to the compressor to be pressurized and sent back through the condenser.

This is why an air conditioner can be thought of as a reverse heater because it does just that – conditions or cools, rather than heats, indoor areas.

 

How Do You Choose An Air Conditioner For Your Home?

The main considerations for any type of AC unit are size (e.g., cooling capacity), efficiency (i.e., energy used vs. amount dissipated), and cost. The first step in choosing an AC is deciding the size you need for your home based on square footage. This will determine other factors such as the number of units and type of unit (e.g., window vs. through-the-wall).

 

What are the different types of air conditioning systems?

Window AC: A window air conditioner is something anyone can install themselves. However, if you are installing an AC unit that weighs more than 40 pounds, it’s a good idea to get some help (which will be required with heavier models). Installing a window unit also requires proper measuring and cutting of mounting brackets and the addition of insulation batting around the inside of your wall for better insulation from weather conditions.

An added bonus when purchasing a window AC? No ducts are needed which means no holes in walls or floors. Window units vary greatly in size, capacity, and energy efficiency but most have electronic controls. Although they are not as energy efficient as central AC units, window air conditioners might be your best option if you are looking for an inexpensive solution to cool a small area or specific room. A window unit can also come in handy if you live in an apartment building with no access to the ductwork.

For instance, some buildings feature dual-zone systems that allow different settings on each side of the same wall. Others give tenants a choice between a central system or individual window units, and may even offer incentives such as free rent for residents who choose the latter cooling options.

 

Central AC:

The most popular approach to home cooling is the installation of a central air conditioning system (also referred to as a split system). As with window units, you need to determine how many BTUs or cooling capacity is needed for your home. Your AC contractor will help with this calculation and the purchase of a unit that fits your needs.

 

Top-loading:

central air conditioning units consist of an outdoor condenser (which houses the compressor) connected to an indoor evaporator coil via copper tubing. The two components are usually located on separate vertical planes, which allows them to fit into small spaces that are not suitable for window units.

This type of system also includes vents and grilles in multiple rooms so they can draw air evenly from various directions. A big advantage when installing these types of AC systems is that installation covers ductwork from the outside unit to all outlets in your home – no holes in your walls or floors.

For this reason, top-loading ACs have often considered the more attractive option because of their compact size and ease of installation and upkeep. In addition, some models may offer more cooling capacity than window units.

 

Bottom-loading:

Bottom-loading central air conditioning systems are similar to top-loading units but they feature an indoor coil on one side of a double wall and the outdoor unit on the other side. This allows for easier access to service components as well as better circulation in smaller rooms where there is not much space between the bottom and the ceiling. It also maintains enough room for insulation batting around the inside of your wall to protect against weather conditions like wind or rain that affect overall energy efficiency. Some versions have remote condensers which means the compressor is located outside the home, while inside air is cooled by an evaporating unit. The AC then discharges warm air back into your home via vents or ductwork. Units of this kind feature a clean design with no external pipes or tubing.

In general, central units are more expensive than window ACs for several reasons: they require professional installation and mess-free maintenance that prevents humidity from damaging furniture; owners must also pay to have building ductwork modified or enlarged when installing central AC systems in homes that do not already have them, and bottom loading versions require having access to the space between floors for other components such as rain puddles.

However, if you plan on staying in one place long-term central ACs may be a great investment for cooling your home for years to come.

Outdoor units also include several other components that will determine how well they work. For example, a humidifier or dehumidifier may be required during the summer and winter months if the outdoor temperature is not high enough to ventilate moisture from inside the house. A thermostat will keep air quality at a constant level by adjusting fan speeds throughout the day to produce an even flow of cool or warm air according to your desired settings.

Top loading ACs are more efficient than bottom loading variants because heat rises up whereas cold drops down – so it’s important to have top access for maximum performance and efficiency levels. It’s usually recommended you should install them above feet and as close to the ceiling as possible, without compromising on cooling efficiency.

To help you determine how many BTUs (or cooling capacity) is needed for your home, there are two things you can do:

Calculate your family’s daily energy usage by multiplying your current primary heating or cooling source with the square footage of your primary living area. For example, if you use baseboard heaters that total up to 100 sq ft in size and run constantly at 1500 watts per hour – then it would be .15 x 100 = 15 kWh/day [1] Calculate the BTU output for one hour using a room air conditioner based on its rating in terms of CFM(Cubic Feet per Minute). For instance, if you want to cool a room that measures 500 sq ft and the AC is rated at 10,000 BTU – then it would be .055 x 500 = 27.5 hours [2]

Add up all your family’s energy usage and divide by 24 or use the same calculation with an air conditioner for one hour to find out how many BTUs you need per hour. The higher this number, the more efficient your system will be when cooling your home. Next, look through our extensive list of air conditioners to see which model you can add to your budget while also choosing a unit that matches its BTU rating.

 

To help you narrow down the options even further there are several other factors that may influence your decision:

What type of home do you live in? A central AC system typically runs off a wall outlet whereas window ACs are designed to be installed inside an open window. If your house has multiple floor levels, requires multi-zone cooling, or has access to attic space where pipes can be installed – then you should opt for a single-hose reversible air conditioner instead of having several individual units that waste energy when moving between floors.

What is the recommended room temperature? For optimal performance 85°F or higher is best, so keep this in mind during the cooler months when it may not produce enough cool air to reach comfortable levels. Many models allow owners to set their desired ambient temperature and will adjust fan speeds as required if temperatures outside increase or decrease significantly.

What is your budget? Prices vary according to the brand, size, and features you are looking for. Not all central AC systems are created equal so it’s important to check compatibility with your existing home cooling appliance before purchasing anything. Measurements must match tolerances given by the manufacturer or else installation will not be possible.

What currently works well in your home? Baseboard heaters, window-mounted coolers, swamp coolers, and ceiling fans make up a part of what can be done to reduce energy costs without having to install a new air conditioning system. You may also want to consider buying components separately; like an AC unit designed for outdoor use if there isn’t any floor space that could accommodate the complete system.

 

Which type of AC is best for your home?

Each design has its own pros and cons, so it’s important to research each variant thoroughly before making a buying decision. If you are unsure of what type of AC unit suits your property best then we recommend going with the most reliable option – which will save you money in the long run.

Many homeowners end up opting for solar panels because they are a great way to reduce utility costs by using alternative energy sources. This is especially attractive if you live in a region that does not have many cooling hours during certain times of the year. Likewise, consider adding ceiling fans into your home to increase airflow throughout large rooms and help circulate cool air where needed.

If you are unsure whether the problem with your AC unit is serious enough to warrant handing over cash – then look for tell-tale signs of trouble such as strange noises coming from the motor, leaking hoses, dripping water from vents, and sweating evaporators. If any of these occur, it’s time to contact professionals in your service area to make sure you deserve the 24/7 service you expect.

When Do I Need To Repair My Air Conditioner?

If it’s been a long time since you last had your AC serviced, have the belt replaced on your unit or changed out for an equivalent one to prevent motor damage. In addition, if there is visible damage to the coils on the evaporator radiator of your unit, that’s another reason to call in a pro for some help.

Signs That You Need Your Air Conditioner Repaired

1) Sibilant hissing noise when running

2) Vibrations felt on walls

3) Leaks in the refrigerant pipes

4) Sudden shutdowns

5) Smells like burning rubber

6) Low pressure

7) Failure to start up

8) Cracks in the condenser coil

9) Rusting of fan blades and evaporator fins

10) Poorly positioned air outlets

11) Installed too close to strong sources of heat

12) Finding water dripping from vents

13) Frequent changes of temperature

14) High operational costs

15) Inefficient operation

16) Short life expectancy

17) Sputtering sounds

18) Slow cool down

19) Uneven cooling

20) Accumulation of wetness around windows

What should you ask yourself when making a buying decision? You should consider how often you plan on using your air conditioner, how much space it needs to adequately cool, what your budget can afford and which unit best suits your needs. Before making a final decision on which AC variant is right for you, know that air conditioners are not created equally. They all have their special features that may be perfect for some households while useless in others.

 

How Long Does It Take To Repair An Air Conditioner?

The length of time it takes to fix an AC depends entirely upon how complex and extensive the needed repairs are. In addition, if you need AC repair services in Seminole, we are here to help you. The most common repair is fixing Freon leaks (which can be done quite quickly). Because Freon gas has developed into a more environmentally friendly substance, there are often many companies willing to recycle these leaked gases versus disposing of them.

 

How Much Is The Cost To Repair An Air Conditioner Over Time?

AC repair costs will vary based on the type of AC unit, amount of Freon necessary (if any), and length of time needed to complete repairs. One cost not included in AC repair is replacement parts such as belts that wear down over time. While these are not technically “repairs”, they can be just as costly when major units need to be replaced due to belt failure. Luckily enough, our St. Petersburg AC repair experts are ready to work with you to ensure that the price suits your needs.

We’ve discussed how air conditioning works, why you choose an AC for your home, how big of a unit you might need, and common reasons for needing AC repair; now we’re going to discuss how much it could cost you to maintain or install one in your home.

 

How much should AC repair cost?

AC repair estimates usually run around $50 to $200, depending on the size of the unit and other factors. If you’re planning to put in an AC unit yourself, make sure you read up on state and local regulations regarding safety practices during AC assembly. They’ll help keep your family safe while lowering potential risks for injury.

How much does it cost to install an AC? Installation costs vary based on the type and model of AC unit purchased, the difficulty of the installation process (such as getting electricity or water running into the house), and whether or not qualified professionals are used for labor. It generally costs between $1,000 and $4,000 to have an air conditioning system installed professionally, with most homeowners spending upwards of $2,500 to $3,500 to have a unit installed.

 

How do I fix my central air conditioner that is not cooling?

Central air conditioners can stop working if the thermostat is not set correctly, a fuse has blown or there is a problem with the electrical circuitry. If your AC stops working properly check these things first before you have it repaired: 1) Check to make sure the thermostat setting is between 68 and 76 degrees F 2) Look for signs of physical damage such as melted wires or broken coils 3) Check fuses and reset breakers 4) Check that water supply lines aren’t frozen 5) Make sure the condenser fan blade turns 6) Clean out debris around motor 7) Look for loose screws inside unit 8 ) Call an AC repair service.

 

How long does it take to fix my AC?

It takes approximately one hour for most AC repair technicians to assess the problem and determine what needs to be done. The time it then takes to fix your AC varies by the type of work that needs to be done as well as how extensive this work is. If you need a new air conditioner installed or you’re having problems with Freon leaks, it should take just over an hour for the technician to complete repairs and finish any necessary services before they leave.

 

How do you diagnose air conditioning problems?

Air conditioning problems are often diagnosed through observation. If your AC is not cooling, the first thing an AC technician will do is check that the thermostat has been set to a temperature that falls between 68 and 76 degrees F. They’ll then determine if there are physical signs of damage such as a dirty coil or broken fan blade; this can help them diagnose what’s wrong with your AC before they ever turn it on. Some air conditioning units have separate diagnostic systems; in these cases, a technician will access these diagnostics and determine which part needs fixing or replacing so repairs can be made quickly.

 

What are the most common air conditioning problems?

Air conditioners can experience a variety of issues, but many AC problems derive from a handful of causes. High temperatures and humidity cause your AC to work hard in order to cool your home; when this happens for extended periods of time, you may need AC repair or replacement. Especially here in Pinellas Park, An abrupt change in weather can also affect an AC’s performance or even damage it beyond repair. The following are some common reasons why your AC might not be cooling:

• Your thermostat is turned up too high – This is probably the reason why eighty percent of household air conditioners run constantly on their coldest setting. For optimum energy efficiency and comfort, set your thermostat between 68°F and 76°F.

• Your filter is dirty – AC filters need to be cleaned out once every month or so, depending on how much air your HVAC system moves through the house. A dirty filter makes it harder for your AC to cool down the home since less air can pass through it, which stresses and strains the unit.

• The condenser coil needs cleaning – Condenser coils are finned metal tubes that transfer heat from the refrigerant back into the outside air; any dirt on these fins can cause them to get hotter, which then causes more work for your AC as well as possibly causing a Freon leak.

• You have a bad thermostat – If you’ve noticed that your AC hasn’t been cooling quickly enough after setting the proper temperature, the thermostat may be malfunctioning or broken.

• The AC unit is not level – Whether your home has a basement or slab foundation, it’s best to have at least one foot of clearance between the bottom of your AC and the floor. If there isn’t enough space for good airflow, it’ll overheat and get more work than it needs to do since air will struggle to pass through. An ac pro can install an air conditioning brace that lets you add a few inches under low slabs or in basements if needed.

• There are unsightly trees nearby – Trees with large branches extending towards your house can block out sunlight and prevent cool breezes from keeping things comfortable inside. While pruning these branches can help, it’s often best to simply have them cut down since branches can cause a lot of damage when they start falling off.

• You need more insulation – By insulating your attic and walls, you can make sure that cool air stays inside the house while hot air is kept out. This will save you money on cooling bills as well as greatly extend the lifespan of your AC system.

 

How can you tell if your AC needs repair?

Your AC won’t always announce its presence by blowing warm air; some problems can be difficult to detect until it’s too late. Luckily, there are a few signs that an AC repair or replacement is needed:

• The air coming out of the vents is lukewarm, not cool

• Your utility bills have been abnormally high over the past month or more

• You’ve noticed mildew in your home; this means that condensation has built up inside your HVAC system.

 

Can you do AC repairs yourself?

There are many common fixes that homeowners can handle on their own. For example, if you notice that your thermostat isn’t giving temperature changes properly, simply reprogramming it may solve most issues. If you aren’t able to figure out what’s wrong with your AC and only have a basic understanding of electrical work, it’s best to call an AC repairman.

 

How do I fix an air conditioner leak?

When it comes to AC leakage, you usually need a professional. If you’re trying to fix a condensation leak on your own by tightening the bolts and replacing the gasket around your unit, this rarely works as intended; instead of creating an airtight seal for proper Freon circulation, your A/C still won’t blow cool air. Usually when there’s a leak in the system, it can’t be fixed without replacing some parts or at least repairing others.

 

Can I fix an AC refrigerant leak myself or do I need to call a professional?

If you’re not familiar with fixing AC systems other than changing filters, condensers, and evaporators; it’s best to call a professional to fix a Freon leak. If it’s your system but you don’t know what the leak is from or how to fix it yourself, then this job is best left for an AC technician who can diagnose and repair the problem properly. If you would like to get the AC technicians from https://gulfcoastacservices.com to take a look at your project, visit our contact us page!

 

A few telltale signs that there’s a refrigerant problem include:

• The compressor outside has started making noise

• Your utility bills have gone up over time

• You’ve noticed moisture on the coils of your air conditioner

Don’t let these problems get worse by going unrepaired; contact an AC pro as soon as possible so they can diagnose the problem and repair it.

 

How do I stop my air conditioner from leaking water?

If your AC has developed a water leak around the base of the unit or on the floor, you’ll want to repair it as soon as possible. It can drip into the walls of your home and damage them, so even if you’re not worried about cold floors in your family room; this problem needs to be fixed.

• Perform regular maintenance – This includes changing air filters regularly to keep dust out of the system and using a leaf blower to unclog drain lines where leaves can block airflow.

• Keep trees trimmed away from windows.

• Insulate properly – If there’s not enough insulation underneath your home, ask an AC pro about adding extra inches with an installation brace that will help block heat from entering through the floor.

• Reduce moisture – If you have a swamp cooler, you might want to consider removing it if your system can handle the extra load. If not, make sure that there is an ample supply of ventilation inside and outside your home.

• Lower AC temperature – The more comfortable you are indoors, the less often you’ll be turning on the air conditioner. Lowering temperatures by 1-3 degrees saves a surprisingly high amount of money over time.

 

Is air conditioner leaking water dangerous?

• Leaking water can make it into your home’s walls and cause damage

• Moisture from ACs can build up inside the house and create mold, which is not healthy for family members

• An leaking AC draws more electricity to cool itself down, thus increasing your utility bills.

• Water damage caused by dripping condensation or ice buildup on units can ruin floors and lumber if left unchecked.

 

Important Things You Need To Know About AC Installation

Can I install an AC unit myself?

Air conditioning installation is a DIY job that even the most inexperienced person can attempt, but it should be left to professionals for 2 main reasons:

1. AC systems contain Freon gas, which is extremely harmful if not handled correctly. If you remove the wrong part or use tools with Freon on them incorrectly, you could be exposed to dangerous amounts of this substance.

2. ACs are larger than people think and require professional installation for safety reasons and optimum efficiency. You wouldn’t try to install electrical wiring yourselves without taking classes and getting certified; don’t attempt air conditioning installation either without proper training first!

 

Can I install an AC in my attic?

No–don’t even try it! Not only will the unit inevitably fail if you install it in an attic, but the process of removing it and reinstalling it correctly will be difficult. It’s much easier to find a professional who can perform AC installation for Attic Installation than it is to go through the whole process yourself.

 

How do I choose an air conditioner that fits my home?

The majority of people buy a larger unit than they need because they don’t know how well or poorly their current AC works without this helpful piece of information. Before getting any estimates about what size unit you’ll need, make sure that your current machine is working properly by using an AC calculator to estimate how much power your existing system uses. This will allow you to get an estimate of AC size that’s more accurate and affordable.

 

Is it hard to install an AC?

It’s not hard to install an AC, but it is hard to install one correctly. If you try to do it without the proper tools or training, then an air conditioning installation DIY job could be a disaster waiting to happen. Without education and experience handling Freon specifically, your safety (and that of your family) is at stake.

 

How long does the installation process take?

The amount of time required for AC Installation varies and depends on several things:

• Size/Type of your home – Remodels will take more time than installations in standard homes

• Whether or not there are obstacles in the way such as large trees or if you have a crawlspace above your unit • Is this AC being installed alone or with another AC?

• The number of installers working.

All things considered, a typical AC installation takes 1-2 days but can take longer if an unfamiliar territory is being explored or you have several units to install at one time. If your home has ACs in more than 1 room, then the job will obviously take longer as well.

• One more thing–the faster that the install crew works, the harder they are likely pushing themselves, which could lead to careless mistakes. Plan for longer installation times so you don’t get an inferior installation because someone was trying to rush through it! Be sure and plan your budget accordingly.

 

What If My AC Unit Falls Out?

That’s a lot of AC units to fall out. But it could happen if you don’t hire the right installation company. Make sure that your HVAC contractor knows what they’re doing and have them provide references before handing over any money! Call their previous clients (with their permission) to get an inside look at how well that company works with its customers.

• If you need help finding a reliable AC Installation contractor, then contact us for assistance; we keep current lists of dependable contractors in all areas and can sort through the poor ones for you!

• We recommend checking reviews on Google or Yelp because these sites are full of unsolicited feedback from real people who’ve had dealings with each business. These folks know what it’s like to deal with each company and can tell you which ones are worth a second look.

• What if your home isn’t equipped for AC repair but the AC is still leaking Freon? Your best bet would be to find an HVAC company or technician that has experience repairing non-standard units such as these. If you’re not sure where to start, ask your local business owners!

• Get three estimates from different companies so you have some wiggle room in your budget for anything that might go wrong. This will help avoid overspending on installation costs later because of unforeseen problems associated with digging up your lawn or dealing with obstacles inaccessible through a crawlspace.

 

How do you secure an air conditioner?

Securing an AC is a matter of safety. If you let it rock back and forth when you’re not using the air conditioner, then you could snap off any brackets that might be connected to your home’s foundation or walls. This can create a risk for injury due to falling debris or even worse, collapsing walls!

And AC units can be heavy, so you need to have multiple people around to secure them properly.

How do you secure an air conditioner? Use brackets that snap right onto your wall or foundation and stay in place with rubber gaskets. To avoid any damage to your home’s structure, consult a contractor beforehand! You’ll also want to schedule a professional installation from someone who knows the ropes. A guy who installs walls for a living will know exactly how to put up the AC unit properly without damaging anything else on your property. He might even recommend one particular brand over another, depending on what he’s used in the past as well as his experience working with those AC units in extreme weather conditions.

 

Will my air conditioner keep me cool during the summer?

Your AC unit will keep you cool as long as it’s working properly. If you turn on your AC and nothing happens, then call a professional! It may be that the entire system has stopped running for some reason. And if you live in a hot climate, then you’ll want to check your air conditioner at the start of every season to make sure it’s ready to go when temperatures start rising outside!

 

How Do I Find Credible AC Installation Companies?

We recommend that you check reviews on Google or Yelp because these sites are full of unsolicited feedback from real people who’ve had dealings with each business. These folks know what it’s like to deal with each company and can tell you which ones are worth a second look.

• Get three estimates from different companies so you have some wiggle room in your budget for anything that might go wrong. This will help avoid overspending on installation costs later because of unforeseen problems associated with digging up your lawn or dealing with obstacles inaccessible through a crawlspace.

• What if one air conditioning installation estimate is significantly lower than the others? There are a few possible reasons for this, but the lowest bidder might not be offering the best service. Here are some reasons why:

1. They don’t have their own insurance and rely on yours instead (and you can bet they’ll raise prices when updating their coverage)

2. Their employees aren’t thoroughly vetted – so you could end up hiring someone who won’t show up to work.

3. They’re going the cheapest route which means they’re using lower quality parts, outdated technology, and poorly trained technicians.

If your AC unit is still covered by the manufacturer’s warranty, then you don’t have much to worry about. You’ll pay for parts and repairs, but most of the labor will be free! This also gives you an opportunity to upgrade any components in need of replacement while dealing with a local technician. And it may help drive down those costs since they won’t need to travel far from their base of operations.

 

Everything You Need To Know About AC Maintenance

What Is AC Maintenance?

Air conditioning maintenance shouldn’t be a mystery. It’s all about giving your AC system a checkup every year to make sure it continues running at peak efficiency and doesn’t break down unexpectedly in the middle of summer! This is an especially important step if you live in a hot climate where temperatures threaten to soar above 100 degrees for most of the year.

• During AC maintenance, we check for problems like excessive wear on fan blades by wiping them down with air compressor oil. If they’re badly worn, then you’ll need to replace them with high-quality parts from your local HVAC company. You might also choose to upgrade fan motors or repair any other components that are showing signs of wearing out over time.

• But don’t worry if you don’t see signs of wear and tear. AC maintenance simply means ensuring that your air conditioner is ready to run at peak efficiency when summer rolls around!

• If a battery dies in your thermostat, then you won’t be able to control the temperature effectively. This can make dealing with hot and cold spots throughout your home a frustrating task! If this happens, call an AC technician – they can rebuild the unit or install a new one depending on how long it’s been since you last had an AC expert take a look at it.

If these simple steps seem too complicated for someone who isn’t handy with tools, then consider hiring an HVAC service company. They’ll know exactly which part needs to be replaced and can handle the installation process without damaging your walls and floors.

It might take a few hours or even a day to complete AC maintenance, but it’s an invaluable investment in comfort that you’ll appreciate year after year. After all, hot weather isn’t something you’ll ever forget – once you experience the sticky heat of summer, your body will be on high alert for any sign of relief from uncomfortable humidity!

• Air filters are extremely important. In fact, they’re often called one of the most essential components in any air conditioning system because they play such a vital role in filtering out harmful airborne particles. This is especially true if there are pets or construction workers inside your home! Routine cleaning helps ensure that dust and dirt don’t settle on coils and motors, causing AC unit failure and expensive repairs.

• During AC maintenance, you may need to replace your filter. And if the air conditioner is running constantly because it can’t keep up with cooling down your home, then you’ll probably want to install a more powerful unit that comes with an upgraded air filtration system.

If you have pets or anyone in your household who smokes indoors (or even on the porch), then replacing filters regularly should be viewed as a mandatory step to creating a safe indoor environment for everyone! This includes children who are allergic to dust mites and other airborne particles – they could experience serious health problems from touching surfaces that accumulate dust. Filters can help reduce allergies and improve lung health, but only if they’re cleaned or replaced regularly!

 

How to Choose a Good AC Maintenance Company

• First and foremost, make sure that your AC service company is fully licensed and insured. Talk to friends and neighbors about the HVAC contractors they use on a regular basis – if you don’t know any people who have service done for them, then start asking around until you find someone whose opinion you trust! A good idea would be to check with the Better Business Bureau as well. They’ll have all the information you could possibly need regarding warranty information, accreditations, complaints from customers, etc.

• The second thing you’ll want to do is get a quote from the company you’re thinking about using. You can always ask for references as well, which is an especially good idea in this case because A/C repair work can be expensive and it’s better to know what to expect before you hire anyone! If for any reason your potential service provider has trouble coming up with at least three names of satisfied customers, then take your business elsewhere – there are plenty of companies that would be more than happy to have your business.

• Once you’ve found a few local AC service providers that seem like they could handle the job (and don’t see anything on their website or social media pages that makes you uneasy), it’s time to call them! First, ask what their policy is regarding diagnosis – you can’t expect a company to work on your AC if they haven’t even looked at it first. Second, ask them about warranty information in case something goes wrong during the repair process, and lastly, make sure that they’ll be able to provide written documentation of all parts used (make sure these are name-brand products) as well as a price list either before or immediately after any repairs have been made!

 

Is AC Maintenance Necessary?

The answer to this question really depends on where you live. If your local climate is extremely hot and humid, then AC maintenance is almost always a good idea! Most people don’t read their owner’s manual before they buy or rent an AC unit – if you’re one of these folks, then take the time to do so now because it will probably save you quite a bit of money in the long run! Lots of household appliances come with built-in reminders for maintenance appointments…

As mentioned previously, routine AC maintenance includes cleaning or replacing filters (if applicable) as well as changing any air filter drier or recharging a desiccant wheel system. By servicing your AC unit at least once per year, you’ll help ensure its longevity and save money in the long run!

You can clean your filter by wiping it down with a paper towel or using a vacuum. Make sure to do this outside, as dust will blow all around if you remove the filter from wherever it is currently installed…if you have pets or small children who like playing barefoot on the floor, then I would suggest always taking the AC unit outdoors to work on it if possible! Be careful not to get dirt or water inside of any electrical parts either – these components are meant for outdoor use but take precautions nonetheless. It’s also important that you turn off your AC before cleaning its filters or else gas could leak out…

If there’s an area near your A/C unit where mold or mildew tends to grow, then you’ll want to keep an eye on it and give your AC regular check-ups. Small amounts of mold can be removed with household cleaners (be sure to test the cleaner in a small area before using!) while larger patches will need professional assistance…the mold could get into your system’s air ducts if not removed properly, which would cause a lot more problems down the road!

• If you’re worried about having enough money for routine AC maintenance, don’t be – there are many companies that offer financing options through local finance companies as well as online lenders. It’s best to do some research beforehand so that you know what to expect when this time comes around. Also, remember that most technicians who work on AC units also work on heating systems – so don’t let the price of routine inspections scare you into thinking that it’s time to replace your AC unit! Sometimes, all a system needs is some professional attention and an air filter replacement.

 

Can I Do AC Maintenance Myself?

If you want to make sure that your AC unit is as efficient as possible but don’t have the budget for an AC service professional, then some DIY maintenance can go a long way! The best way to get started with this is by reading your owner’s manual…this will tell you what kind of tools and supplies you’ll need to perform basic maintenance tasks. It also outlines how often certain parts should be replaced and/or cleaned, so be sure to follow these guidelines in order to avoid any issues later on (for example, if the inside of your main air filter has mildew growing on it, then it’s probably time for an AC replacement!)

 

Ok, let’s get going – here are some simple maintenance tips:

• Make sure that you keep your AC unit clean! This can actually be done routinely by taking off all the leaves and debris around it on a weekly basis to help with its functionality. It’s also a good idea to use a vacuum cleaner or hose to clean out any cobwebs, grime, plant matter, etc., from inside of your AC’s in-ductwork – this helps prevent mold or mildew accumulation and makes for easier airflow too…

To do this, simply take off the grill at the front of your AC unit then vacuum away! If there is a buildup on any of your unit’s parts (be sure not to spray water directly into any electrical components either!) then you may want to consult with an HVAC professional to determine if it can be cleaned or should instead be replaced.

Any time you run your AC unit, make sure that the surrounding area is well-ventilated! If you live in a place where summers are scorching and temperatures reach the high nineties, then I would suggest moving somewhere else…you’re just asking for trouble by living in a hot place like this! With the current global warming epidemic being what it is, we may all end up having to move someday soon…they say that California will be completely submerged by water within a few decades if drastic actions aren’t taken against climate change. But for now, there are things that everyone can do to reduce their carbon footprint:

– Try not to use your AC system too much – if you find that your home is getting too hot, then just open some windows or shut off the AC system completely for a few hours. Doing so can help keep your utility costs down since the air outside may be cooler than inside your home!

• If you have an existing AC unit but are thinking about installing another one just in case, make sure to put it in a well-ventilated area where there isn’t any flammable debris like leaves or dead grass…you wouldn’t want anything catching on fire when the new AC kicks up dust and particles while being installed!

Air conditioning units work by cooling down their immediate surroundings…if they are not placed correctly with respect to wind direction, then this won’t work out as efficiently as possible. When AC equipment is installed, there are airflow charts that can tell you the best direction to face your AC unit in with respect to the main wind patterns of your area…it’s a good idea to keep these things on hand when using your AC just in case it isn’t cooling down your home as well as you had hoped!

As I mentioned earlier, replacing or maintaining an AC system according to your owner’s manual will ensure better efficiency and perhaps even save money. If you choose not to do this then make sure that the AC service technician talks about how much this could be costing you over time before deciding whether or not it’s worth it. However, if all else fails then I’d say just bite the bullet and invest in a new AC – it’s always better to be safe than sorry!

 

Important Questions and Answers About AC Replacements

Can I replace my AC unit myself?

The answer to this question depends on your current level of expertise and how much time you can dedicate to replacing the system. If you have an existing AC unit that is not working properly then it might be easier (and less expensive) for a professional technician to diagnose and repair the problem but if your existing air conditioning equipment has simply reached its end-of-life, then replacement could be your best option. If you are curious about AC replacement, also make sure to visit our about us page to learn more about the replacements we do.

So before you attempt AC replacement, why don’t you call up a local HVAC company and get an estimate? They may be able to help avoid costly mistakes and the estimate might be within your budget, especially when most reliable HVAC companies provide financing options.

 

How often should you replace your AC?

If your current AC is on its last leg or otherwise just doesn’t work well anymore, then you should probably consider replacing the unit if you are looking to maximize energy efficiency. However, replacing an air conditioning system too early might give you a false sense of security about how long it will be before your home needs another replacement – so unless it’s absolutely necessary, try not to run out and get a new AC installation right away.

I can only say that as long as my existing AC unit is working properly at any given time, I plan on keeping it around! As far as I’m concerned there isn’t much purpose in thinking about what might happen next month or next year; we all have better things to do with our time than to worry about AC replacements.

 

Can my air conditioner last 30 years?

This is a tricky question because it depends on a combination of factors including how often you use the AC, what kind of system you have now (the age and quality), and how well you maintain your air conditioning equipment. In addition, there are variables outside your control like climate conditions that can affect air conditioning life expectancy…even if all these other factors are optimal for AC life expectancy then there’s no guarantee that the unit will last 30 years!

What I’m trying to say is that the best way to help maximize AC life expectancy is by replacing an old, inefficient unit with something new; it’s always better to be safe than sorry!

 

How long does it take to get my old air conditioner replaced?

Replacing an air conditioning system really depends on what kind of equipment you are replacing. If it is a simple AC replacement then it could be completed within a day but if the job requires complete AC installation or ductwork then this can take several days to complete as well.

 

Clear signs that you need new air conditioning:

If your air conditioner has broken down completely and will not turn at all, most homeowners tend to replace their unit sooner than later because waiting for AC repair in some areas simply means paying more money! A good rule of thumb is if it hasn’t been working for more than two weeks then chances are that there’s something wrong with the system and someone needs to look into this ASAP – replacing an old or broken-down AC unit can save you money in the long run!

If your air conditioning isn’t keeping up with the heat, then it’s probably time to consider AC replacement as well. Since this is an issue that could get worse over time (you may not feel the effects of poor cooling right away but eventually you will!), don’t let yourself become a statistic and concentrate on getting an estimate for AC installation or AC repair from a local HVAC professional!

Basically, if something doesn’t seem right about your current AC system then chances are good that something needs to be done – so give us a call today and we’ll talk more about how soon you need new air conditioning!

 

What are the signs of a bad AC condenser?

If your AC is making a lot of loud noises or if you are seeing pools of water on the ground below where your outdoor unit is installed, these may be signs that something needs to be done ASAP! Bad air conditioning condenser problems can cause leaks and even explosions in extreme cases so try and get this checked out as soon as you possibly can.

 

How do I tell when it’s time for an AC replacement?

Doing some basic maintenance on your AC system could help you avoid more costly repairs down the line – but at some point, you will most likely want to replace an old air conditioner with something new (if only because older units use a lot more energy which results in higher utility bills)! To figure out whether or not now is a good time to replace your AC with something new, here are some things to look for:

– If your air conditioning is too noisy then this may be an indication that it’s about time to replace the unit. This doesn’t necessarily mean that your AC will need a replacement right away but it could be one factor in a decision like this. Ask yourself if you really need the sound of an old AC system; if other homeowners have made similar complaints then there may be more at play than just annoying noise!

– Any damage or corrosion on an AC surface is generally considered a bad sign so try and keep things clean and dry as much as possible! It might seem obvious, but keeping leaves and debris away from outside units can do wonders for AC longevity.

– Foul odors or strange smells coming from an AC unit could mean that mold is growing in the ventilation, which means you’ll need to get this checked out as soon as possible! Mold can cause health issues and pose serious threats to humans so make sure you take a look at your AC system if anything seems fishy.

Winter is Coming!

While doing ac repair, ac maintenance or ac installations, customers often inquire about air quality products and if they are worth the money. In this blog I will review some of the new technologies available to consumers and average costs to get them installed in your home.

UV Bulbs – When UV technology first came out it was being sold more as an air purifier. On a simplistic approach UV-C light does two things; 1 – Kills organic materials, 2 – Breaks down porous non-organic material. UV-C kits are great at keeping the inside of the air handler clean including the coil therefore, that is what we sell them for. They are so good at keeping the coil clean that we recommend them to every customer. The reason they are not as efficient as an air purifier is due to the speed of the air moving through the air handler. A three ton system is rated to move 1200 CFM (cubic feet per minute). At that speed, a lot of organic material will pass through without being destroyed by the light. A typical UV kit installed over the coil should cost around $250 and the ballast should have a lifetime warranty.

Ionization – The way ionizers remove particulates from the air is by sending out lots of negatively charged ions. As they float through the air, they attach themselves to the particulates making them heavy. This causes them to fall to the ground or another surface. After installing an ionizer in a home there will be a sudden accumulation of dust around the house which needs to be cleaned up. The downside of ionizers is that the particulates are not captured until you vacuum up the dust caused by the ionization process. A whole house ionizer installed in your AC system can cost from $600 – $1900.

Media Filtration –  Filtration has long been a great way to take particulates out of the air. One of the best ways to achieve this goal is to have a 4″ media box installed in the return of your AC system. It is however very important to purchase a media box that is matched to you system so the static pressure remains within the recommended ranges of the manufacturer. High end media does a great job of removing particulate from the air and based on individual circumstances only need to be changed semi-annually or annually. A 4″ Media box installed in your system can cost $450 – $750 and includes your first filter. Filters run from $70 – $150.

Air Scrubbers / Purifiers – These products are finally becoming affordable for residential customer and are excellent products for homes struggling with allergies. Based on commercial technologies used in hospitals for many years, they combine multiple technologies that actively eliminate bacteria, spores, allergens, viruses, odors & smoke in the air and on surfaces. They combine Photo-catalytic + Silver Ion Contaminant Oxidation, Ion / Plasma Generation & UV-C Light Technology. They install in the supply plenum and tie into the 24 volt system of the air handler. Some products have a plug-in option for an additional UV light to install over the coil. A typical scrubber / purifier installed in your system will run from $750 – $1250 and should have a lifetime warranty on the ballast.

In summary there are several technologies available to help improve your air quality. We always recommend installing a UV light over the coil and then either your choice of 4″ Media, Air Scrubber / Purifiers or both.

To Heat Pump or Not to Heat Pump?

A heat pump is a type of AC system that uses the cooling process in reverse to generate heat. When bidding residential systems, I often ask customers with straight cool systems if they would like to upgrade to a Heat Pump. This question is often followed by the customer asking me what the difference is between the systems. In this blog, I will go through the process of how a heat pump works along with the Pro’s and Con’s of upgrading to this type of system. Before we do that, I want to state that all split and package systems have electric heat kits in the air handler portion of the system. Essentially an electric heat kit is resistance heat like a toaster. In a straight cool system, the electric heat kit is the only source of heat.

Before we start talking about what a heat pump is, let’s first review the basics of a straight cool system. A straight cool system pumps (a compressor is really just a pump) Freon through a high-pressure liquid line (smallest of the two copper lines) to the evaporator coil in the air handler. When the Freon hits the air handler, it expands and becomes a gas. The process of the Freon changing from liquid to gas in the evap coil is what makes it cold (it’s science). When air blows across the evap coil, it picks up the cold and the freon absorbs the heat through the coil. Freon leaves the evap coil through the low-pressure gas line (bigger of the two copper lines which is insulated because it is still cold) and heads back to the condensing unit where it runs through the condenser coil. While running through the condenser coil, the Freon bleeds off the heat with the help of the condenser fan and then returns to a liquid state to be pumped back through the process again.

So now that we understand cooling basics, let’s start reviewing how a heat pump works. In the most simplistic form, a heat pump runs the above process in reverse so that the evap coil in the air handler is providing heat and taking away cold. There are some mechanical and electronic components in a heat pump system that allow this process to work. The first is a mechanical reversing valve and when the thermostat is set to heat, its function is to reverse the direction of the flow of Freon. Next is an accumulator which is essentially an extra tank that holds Freon in its gas state. From an electronics standpoint, there is a defrost sensor and a defrost circuit board. While running in reverse to take the cold out of your house, there is risk of the compressor freezing over. The defrost sensor monitors that temperature and when triggered, tells the defrost board to activate. In this mode, it will turn off the fan on the outdoor unit, send the system back into cooling mode and turns on the back-up heat strip to keep the air inside tempered. Once the defrost sensor determines there is no danger of icing up, it sends the system back into heat pump mode.

Heat pumps work the best when the outdoor ambient temperature is around freezing or higher. They lose their effectiveness when the temperature gets too cold outside so they are very popular in southern states. Most installers will put a 5 kilowatt electric heat strip (one of the smallest) in the air handler of a heat pump system for times when it is really cold outside and the heat pump cannot keep up. You may notice your thermostat going into “auxiliary” or “2nd stage” heat. That is when the heat pump is running concurrently with the electric heat to keep up with the demand.

Pros and Cons

The entire creation of a heat pump system is targeted to one thing…energy savings you can see on your electric bill. A heat pump can save you 30% or more vs. the electric heat in a straight cool system. As far as cons, a heat pump system can cost $400 – $900 more than a straight cool system. The final con would be the potential failure of a reversing valve, defrost sensor or defrost board which are components only found in heat pump systems.

In summary, if you like it toasty in the winter while spiking your eggnog instead of your power bill, a heat pump may be right for you. Lastly, I want to call-out this entire blog was focused on heat pumps. While cooling your home, there is no difference between a heat pump and a straight cool system. A 15 SEER heat pump running in cooling mode provides the same energy savings as a 15 SEER straight cool system
