Dispelling 3 Common Myths On Cooling

Dispelling 3 Common Myths On Cooling

Fall may be upon us, but any native Floridian knows that the Sunshine State will remain a sweltering environment for several months to come. That being said, your efforts to keep your home cool will stay firmly in place until the temperature finally starts to reflect the season. And while you may have some preconceived notions on how best to stave off bills that rocket with the daily projected highs, we’re here to bust some myths that may actually cost you more.

MYTH:“If I switch my system back and forth between “OFF” and “ON,” I’m just wasting my money.”

REALITY: On the contrary—by leaving your system running to keep your home cool while you’re out and about, you’re actually running the risk of increasing your energy bills. Contrary to popular opinion, your HVAC system will not work harder or spend extra energy to cool your home back down if it was left in the “OFF” position while you were gone. Particularly when you’re away for extended periods of time, turning your HVAC system off when you’re not home will actually save you money and take little to no extra effort to circulate cool air again.

MYTH:“My home will cool down faster if I set the thermostat lower.”

REALITY: Simply put, your unit will take the same amount of time to cool your home down, regardless what temperature you set your thermostat to. If anything, your unit will run for longer periods of time—rather than faster—meaning you could actually lose money by trying to push it to act quicker. Moreover, you might waste even more energy and more money if you forget to change your settings back to your usual preferred temperature.

MYTH: “I can save money by closing the vents in the rooms I don’t use often.”

REALITY: By doing this you’re actually suffocating your HVAC system (thereby damaging it) and burning through energy (thereby raising your bill). This myth, in particular, is one of the most commonly believed and, by attempting it, you’ll be increasing the amount of pressure placed on your ducts by impeding your unit’s ability to “breathe out.” Your indoor blower may end up with damage, which in itself costs money, but you’re also forcing your HVAC system to work in an inefficient manner, increasing the amount you’ll have to pay for your energy bill.

What Temperature Should You Leave Your Central Air Conditioning On When Nobody Is Home?

What Temperature Should You Leave Your Central Air Conditioning On When Nobody Is Home?

What serves as the “best temperature” for your home is naturally going to vary from person to person. But, while we can’t tell you what the perfect temperature for you is, what we can do is tell you how to best save money on your energy bill when nobody is home.

As tempting as it may be to leave your HVAC system running cool for the entirety of your absence, this practice is actually inefficient and will cost you more money than you may realize. We understand, though, if you don’t want to turn your system off completely. To find the middle ground, you’ll want to factor in the outdoor temperature, whether or not you have any furry family members being left in the house, and when you plan on returning.

To start, match your thermostat setting to the outside climate, you’ll essentially be maxing out the efficiency of your system. For example, if the temperature outside is 82 degrees and you set your thermostat to 82 degrees, your AC will not be actively blowing cool air, but it also will never get any warmer than about 82 degrees exactly. Regardless of how long you leave your system on, it will not be consuming additional energy or increasing your bill.

That being said, just because there are no people left inside doesn’t mean there is nobody left inside. If you have a cat, dog, or other pet who will be at home while you’re out, and the projected high for the day is dangerous, you don’t want to burn out your four-legged family member by meeting the outside temperature. Set your system to a warmer-than-normal-but-still-comfortable temperature to prevent your animal from suffering heat stroke. In this case, safety overrides financial efficiency.

Finally, if you’re going to be gone for a long period of time and your house will be completely and entirely empty, you’re better off switching your system to the “OFF” position altogether and pinching every penny you can. If you know you’ll be back relatively shortly, however, simply raising the internal temperature for awhile will afford you some comfort while still saving a little more money.

If you have any further questions on how to get the most bang for your buck when it comes to your HVAC system, contact Bold City Heating and Air today. Call us to schedule an appointment, check your unit for optimal use, and experience the bold difference!

Quick! What do I do when my AC unit has frozen over?

Quick! What do I do when my AC unit has frozen over?

Sometimes, winter hits your HVAC unit before it actually hits the state of Florida. But don’t panic! While we might not all be acclimated to handling the cold here in the Sunshine State, dealing with the frigid problems your HVAC unit faces doesn’t have to be so intimidating. In fact, the steps to prevent any further damage are simple.

To start, switch your unit’s thermostat to the “OFF” position. If you keep you keep it in the “COOL” position or simply keep it on, you run the risk of making the problem worse or, specifically, damaging your compressor. As the ice may be a result of too-cold refrigerant in your system, this will be your first step because it will prompt your unit to stop sending refrigerant to the compressor itself.

From there, be sure to switch your fan setting to the “ON” position to help the system defrost. You’ll want to leave it in this position for a few hours, depending on just how much ice has developed and covered the unit. If you have trouble dealing with how hot your home gets while waiting for it to thaw, we suggest running to the movie theater or meeting up with your friends for a couple of hours so that you yourself don’t have to melt with the ice while you wait.

During the process, however, you will want to keep an eye on the drain pan and condensate drain. Be sure the water doesn’t clog or overflow, and think about laying down some towels in the event that there is a leak from the melted water.

In many cases, this buildup may be the result of an air filter in dire need of changing. Once you have the unit properly thawed and dried, your next step should be to check the filter, replace it, and continue watching your system for a couple days to make sure there’s no reappearance of ice.

If your unit begins to freeze over again or your filter showed clean the first time, you’ll want to call a professional to take a look at your HVAC unit, and Bold City Heating and Air is here to help you avoid the feeling of an icy panic. Call us today to schedule an appointment and get to the bottom of your unit’s premature winter. Experience the bold difference.

Why One Spot In Your House Is Hotter or Colder Than Normal

Why One Spot In Your House Is Hotter or Colder Than Normal

At one time or another, almost all of us have to ask ourselves the question of why one room is either hotter or colder than the temperature permeating the rest of the house. After all, padding into one room knowing you have to be adequately bundled or even underdressed can be both uncomfortable and inconvenient. But if you’re wondering why you’re suffering through a temperature imbalance, we’re here to help you figure what you can do about it.

  1. Check Your Vents

    Did you close your vents? Many actually do under the misguided belief that they’re saving energy. On the contrary, closing your vents can produce pressures that force your HVAC unit to work harder, thus increasing your energy bill. Moreover, it goes without saying that, if you close your air conditioning vents, air will not be able to reach that room. As a result, that particular room will be at the whim of the seasonal weather. Particularly if your walls are not insulated, heat from the now-warmer spot of the house will actually leak outward, creating other pockets of warm space in your home.

  2. Check For Areas Vulnerable to Outside Temperatures

    If your windows or doorways are not properly sealed, they’ll likely let the heat or cold of the outside seep in, creating a space of varying temperatures within a room. Be sure to seal these areas with caulk or place thick drapes that help prevent temperatures from essentially leaking through glass as a means of insulating your rooms. Additionally, check for outside factors that may also work against your thermostat setting. For example, having a window that is consistently facing the sun in the afternoon will drastically change the temperature in that room, even if it is sealed properly.

  3. Determine If Your Layout Works Against Your HVAC

    Sometimes a room will simply not get the circulating air from your HVAC system if it is physically farther away from the system itself. Particularly if your HVAC system is improperly sized for your home, not every room will be able to receive the same air, resulting in rooms that maintain varying temperatures.

If you’re looking to return your home to a temperate and equal climate, don’t wait to find out what’s wrong. Call Bold City Heating and Air today to schedule an appointment and experience the bold difference!

How Does the Florida Humidity Affect Your HVAC, and What Should You Do About It?

How Does the Florida Humidity Affect Your HVAC, and What Should You Do About It?

Any native Floridian will tell you that the humidity is one of the main reasons the Florida heat can feel so intense and suffocating the moment you walk out the door. Going back inside is sometimes the only way to find reprieve from the oppressive weather, especially as air conditioning units are specifically designed to cool your home by removing moisture from the air. But, particularly as hurricane season goes into full swing and moisture seeps back in, how does the humidity affect your HVAC’s ability to function properly?

Put simply, an increase in indoor humidity will negatively impact your HVAC unit. This is because the more moisture there is, the more energy has to be expended in order for your unit to effectively cool the air. Therefore, not only will your energy bill go up, but you will also run the risk of overextending your unit and its evaporator coils. When you force your HVAC unit to work beyond its own ability, it won’t be able to function and the air in your home will more than likely continue to feel warm and uncomfortable.

To prevent this, there are a few different things you can do. For one, you can install an actual dehumidifier onto your air conditioner. This way, your HVAC unit has to work less to remove moisture, and temperature control and humidity control are controlled all in the same place.

Additionally, you can keep the fan setting on your thermostat in the “AUTO” position, not the “ON” position. This way, your fan won’t be running constantly; rather, the fan will not continue working between cooling cycles and your evaporator coils will have time to drain. In other words, running your unit on “AUTO” allows your system to run more efficiently and reduce your energy usage.

Finally, you should try to change your air filter regularly. As dust and dirt builds up in your filter, your unit will basically become clogged and ineffective in its attempts to remove moisture from the air. You can usually adhere to changing your filter every couple of months, though the more intense the humidity becomes, the more often you’ll want to check it.

Want to make sure your air conditioning is in peak condition before a larger storm or hurricane heads your way? Call Bold City Heating and Air today to schedule an appointment. We’ll make sure you’re all set to keep humidity out, optimal comfort in, and experience the bold difference.

Five Easy DIY Window Projects to Save Money on Cooling Costs

Five Easy DIY Window Projects to Save Money on Cooling Costs

According to the Department of Energy, heat gain and heat loss through windows are responsible for 25 percent to 30 percent of residential heating and cooling energy use. If this is something you struggle with, it’s important to know that there are a variety of solutions that are both cost-effective and require little time to implement. Before you reach for your thermostat, try these five easy fixes first:

  • Purchase Blackout Curtains:

    Blackout curtains can help you keep your energy bill down year-round in that they help insulate a room in the winter and block out the hot Florida sunlight during the summer. If you happen to have extra fabric laying around the house, tailoring the fabric to meet the dimensions of a window is about as easy as it gets. Otherwise, blackout curtains and coverings are easily purchased from the store at a low cost.


  • Install Awnings:

    If you’re looking to block light from the outside rather than the inside, awnings are simple and traditional. Shade will be cast over your window and, depending on the material you choose, rays from the sun may be directly absorbed, thus keeping your house cool without lowering the thermostat.


  • Seal Off Unwanted Airflow with Caulk:

    You may not even realize just how much warm air is either leaking into or out of your home from around the window edges. A quick fix to stopping this unintentional airflow is caulk: a waterproof filler. Not only is caulk super inexpensive (think around $3 a tube), but it’s also easy to apply. Just clean the edges of your window, fill the caulk in at the joints of where the window meets the wall, and let it dry to seal.


  • Reflect the Heat With Window Film:

    Window films are great in that they afford you more privacy and literally reflect the heat, all without obstructing your view. Plus, they work well for the cold months—just like blackout curtains, properly applied window films help to keep in the heat when the chill starts to get to you, allowing you to keep your energy bill down regardless of the season.

Why Should You Buy A New Air Conditioner If You Own an Old Home

Why Should You Buy A New Air Conditioner If You Own an Old Home

According to the National Association of Home Builders, the average life expectancy of an HVAC unit is approximately 10 to 15 years. In this case, if your home is over 30 years old and you’ve never replaced your air conditioning system, then it is two times over its traditional “lifespan.” Even if your home is only in this 10-to-15-year window of time, you’re still more than likely due for a brand new unit. Not convinced or simply wondering why this is? Here are our top four most common and hazardous problems associated with old air conditioning units, ranging from bad to worst:

  1. Overall Cost:


    The older your air conditioning unit is, the more money will need to come out of your wallet in general. For one, maintenance will continue to cost more as your unit ages, not to mention the frequency with which it will need maintenance will increase over time. The more your unit ages, the more it will break down and the worse the break downs will be. Plus, your electric bill will likely increase as your old air conditioner demands more energy to function at the same level. Overall, a new air conditioner will likely cost less than extensive and repeated repairs.


  2. You’ll Suffer During the Summer (And Just About Any Other Month)


    Typical air conditioning aging involves one major nuisance: inefficiency. Any Floridian can tell you that the failure to keep air cool is entirely problematic during just about any and every month, and certainly nobody wants to find themselves sweating unexpectedly while indoors in the middle of August. Dirty filters, freezing coils, and low air flow will make it difficult for your unit to effectively cool down your home, and for your unit to fail you during summer could have adverse if not dangerous effects on your physical health.


  3. Refrigerant Leaks:


    Low refrigerant (otherwise known as Freon) is a general problem of outdated air conditioning units, and typically this will contribute to warmer airflow in your home. However, the older your unit is, the more likely it is that the refrigerant itself will actually start to leak. This type of leak may not be as dangerous to you as electrical issues, but it is harmful to the environment and can also cause permanent damage to your overall air conditioning unit if the leak is extensive enough.


  4. Old Wiring is a Danger to Your Home:


    According to the National Fire Protection Association, 14 percent of electrical house fires between 2007 and 2011 were caused by old wiring in HVAC units. Even when old wiring isn’t threatening to set your property on fire, it can still cause repeated electrical outages that are inconvenient at best and still dangerous at worst. Moreover, as this type of wiring is kept hidden within the unit, you won’t be able to see for yourself when there’s an internal problem. Replacing your unit isn’t just necessary for the sake of technological age, but for the sake of modern safety.

A Guide to deciding on a Replacement Thermostat

Are you looking for a new thermostat?

Regarding these 3 steps to finding a thermostat replacement:

  1. Choose the type of thermostat you want
  2. Be certain it works within your home and HVAC equipment
  3. Contact a professional to install it

Step #1: Choose the type of thermostat you want

There are 3 main types of thermostats

Manual thermostats

These are the most common type of thermostat and they are considered mechanical or non-programmable thermostats. You have manually to turn your HVAC on and off and control the temperature.

There are 2 types of manual thermostats for you to buy:

  • Digital, which use arrow buttons to control temperature
  • Analog, which have a dial to change temperature

Unfortunately, some models of manual thermostats cannot give you the exact temperature control. Some manual thermostats have about a +/- 3° differential, while other types of thermostats only have a +/- 1° differential.

Programmable thermostats

Programmable thermostats are programmed to save you money on your energy bills. According to Energy.gov, programmable thermostats can save you up to $180 per year in lower energy bills.

For example, if your week consists of 5 work days for 8 hours, this means 40 hours every week you have the opportunity to dial back your AC or heating system to save you money. Yes you can turn your HVAC system off with a manual thermostat, but this means you’ll ultimately come home to bad temperatures.

A programmable thermostat can fix this problem by telling your HVAC system when to turn on/off and to what temperature. This way you don’t have to do it manually.

Here’s how it’s done:

If you leave your house at 8 am you can program your thermostat to automatically raise or lower your home’s temperature by 10° right at 8 am. This will allow you to set it to automatically return to better temperatures at 5:30 pm, so that the house is good when you return home.

Smart thermostats

Smart thermostats are programmable thermostats that you can control from your computer, tablet or phone. This can allow you to adjust your home’s temperature automatically. They are the most expensive, but they have the best comfort features and save you money every month on your utility bills.

Comfort features you can find on some programmable thermostats are:

  • Touch screen displays
  • Voice instructions and notifications
  • Dirty air filter alerts
  • Multiple programmable schedules (weekday, weekend, vacation, etc.)
  • Schedule “learning” capabilities (where the thermostat learns your daily schedule automatically instead of you having to program it)

Step #2: Be certain it works with your home and HVAC system

After you decide which thermostat you need you’ll need to pick a particular model that works with your HVAC system.

To be certain a thermostat works with your system note it can work with:

  1. Your system’s specific voltage
  2. The location on the wall
  3. The # of heating/cooling stages your system has

#1: Check your system’s voltage

By your HVAC system being a low voltage, a millivolt, or a high voltage system you’ll need a thermostat that works with your system’s voltage requirements.

Most thermostats work with low voltage systems. An easy way to tell is if you have wall or floor heaters or an electric baseboard heating system. If you do then you have a low voltage system. They are after all the most common.

How do you confirm your thermostat works with a low voltage system?

Look at the specs on the thermostat box or manufacturer label, but if you’re online, look for the words “low voltage”.

#2: Make sure the thermostat fits on your wall

Remember that your new thermostat will fit in the exact same spot as your previous one. This way you won’t have to worry about rewiring it. This also makes your home zoned, each zone has its own thermostat, therefore you will need to purchase multiple thermostats.

#3: Have a professional decide the number of heating and cooling stages your system has…

The “Stages” are how many speeds your AC or heating system can run.

Your HVAC system will fall into 1 of the following categories:

  • 1-stage = the system works like an ON/OFF switch
  • 2-stage = the system works at a LOW/HIGH speed
  • Variable speed = the system can ramp up or down its cooling/heating levels depending on what is needed at any given time.

In the all run you will need to know if your thermostats wiring works with the number of stages your HVAC system has.

It is best to have a professional handle this for you since this has you read your current thermostat wiring.

Step #3: You should have a HVAC expert to help you install it

An improperly installed thermostat (due to a DIY attempt) can result in:

  • HVAC system malfunctions
  • Lowered comfort (improper wiring can even leave you without cold/warm air)
  • Expensive repairs
  • Unnecessarily high monthly energy bills

By hiring a professional this ensures that your thermostat will work with your system, and that you won’t run into any problems.

Is a Variable-Speed Air Conditioner Worth the Cost?

Is a Variable-Speed Air Conditioner Worth the Cost?

If you can swing the high upfront cost, then yes, most FL homeowners will find that
variable-speed technology is “worth it” when compared to single-stage/single-
speed ACs.

Note: The term “variable-speed” can refer to two different components in your AC: the
compressor and/or the blower motor. If you’re looking at an AC that’s labeled “variable-
speed”, be sure to ask a licensed technician or manufacturer which component(s) has
“variable-speed technology”.

Variable-speed vs. single-stage/single-speed units: How do they work?

Note: To be more specific, the terms “single-stage” and “two-stage” refer to AC
compressors, while “single-speed” and “multi-speed” refer to blower motors.

Think of single-stage/single-speed units as operating like a basic light switch: they work
at one level—HIGH, which means when they’re on, they’re going full blast at 100%
capacity.

Variable-speed technology works more like a dimmer switch: they can adjust to any
operating capacity needed.
In fact, variable-speed units can operate anywhere
between 10% and 150% capacity, making them much more efficient at keeping homes
cool in the summer.

Let’s look at how a single-speed/single-stage unit would handle the extreme
temperature versus a variable-speed unit:

  • Single-speed/single-stage AC: It turns on at full-blast, cools down your home
    quickly, and then shuts off. These short ON/OFF cycles repeat continuously,
    resulting in hot/cold spots in your home and inconsistent indoor temperatures.
  • Variable-speed AC: It initially blasts at 150% to cool the home quickly, but then
    automatically ramps down to 30-40% capacity once the indoor temperature is
    close to the desired temperature. At 30-40% capacity, the AC provides a slow
    and steady stream of cool air.
    This results in even cooling throughout the entire
    home and indoor temperatures that precisely match the set temperature.

Benefits of a variable-speed AC:

  • More comfort. A variable-speed AC’s longer run times and lower speeds means
    cool air is steadily pushed throughout the whole house to provide even
    temperatures. Longer run times also allow for better dehumidification.
  • Lower electric bills. The ability to ramp down in speed means that your AC
    uses only the lowest amount of electricity needed, meaning lower energy bills
    throughout the year.
  • Quieter operation. Since variable-speed blowers can operate at any capacity
    (not 100% all the time), they have lower decibel levels than other AC units.

The downfall: Variable-speed costs more upfront

The cost to install a variable-speed AC unit is about $4,000–$8,000 more than other
units. The total cost of a variable-speed AC installation is usually around $12,000 to
$16,000.

Fortunately, variable-speed technology isn’t the only factor that can raise the upfront
cost. In fact, the overall cost of an AC installation varies depending on many factors,
including:

  • The size of your unit
  • The efficiency you choose (SEER rating)
  • Features you add (like noise reduction or air quality features)
  • The contractor your choose

Are you on a budget? Try a middle-of-the-road option

If you can’t swing the high upfront cost of a variable-speed AC, but you want more
comfort than a single-stage/single-speed unit. Try considering one of the mid-range unit
options below:

  • Two-stage: If an AC is a “two-stage” unit, it means that the compressor—the
    part in the outdoor unit that pumps refrigerant through your system—has two
    operating capacities
    (high and low).
  • Multi-speed: If an AC is a “multi-speed” unit, it means that the blower—the part
    in your indoor unit that blows cool air throughout your home—has up to five
    preset speeds
    (like a ceiling fan).

Two-stage/multi-speed units keep your home closer to the set temperature than single-
stage/single-speed ones, but still don’t offer as precise temperatures as variable-speed
units

Variable-speed vs. single-stage/single-speed units: How do they work?

Note: To be clear, the terms “single-stage” and “two-stage” refer to AC compressors, while
“single-speed” and “multi-speed” refer to blower motors.

Think of single-stage/single-speed units as operating like a basic light switch: they work at one
level—HIGH, which means when they’re on, they’re going full blast at 100% capacity.
Variable-speed technology works more like a dimmer switch: they can adjust to any operating
capacity needed.
In fact, variable-speed units can operate anywhere between 10% and 150%
capacity
, making them much more efficient at keeping homes cool in the summer.

Benefits of a variable-speed AC:

  • More comfort. A variable-speed AC’s longer run times and lower speeds means cool air
    is steadily pushed throughout the whole house to provide even temperatures. Longer run
    times also allow for better dehumidification.
  • Lower electric bills. The ability to ramp down in speed means that your AC uses only
    the lowest amount of electricity needed, meaning lower energy bills throughout the year.
  • Quieter operation. Since variable-speed blowers can operate at any capacity (not
    100% all the time), they have lower decibel levels than other AC units.

How to Unfreeze Your AC Unit Fast

If you see ice on your indoor or outdoor unit, it is a clear sign that there is something wrong with your AC unit.

The worst part is if you keep running the AC, you risk damaging the compressor— $1,495+ AC repair (more on that later).

With that being said, follow these steps to unfreeze your AC unit quickly:

1- Turn the thermostat from COOL to OFF

2- Turn the fan setting to ON

3 -Check your filter and replace it if needed. If the filter isn’t dirty, call a professional before turning the AC back on.

Note: These instructions will simply help your AC to unthaw but won’t guarantee the prevention of further damage due to falling ice chunks, water on controls, water damage, etc.

In this article, we will explain the rationale behind each of the steps above. We will also provide help tips that will prevent expensive water damage, or a busted AC unit.

Your AC is freezing up for a reason, and simply thawing out the unit won’t fix the root problem. If you want to solve the problem at the core, we can help. Just contact us.

Step 1: Turn the thermostat from COOL to OFF

With ice being on the AC unit this means the refrigerant, the liquid that cools your home’s air, is much colder than it should be. If that cold refrigerant is sent to the outdoor unit, it could kill your compressor. The compressor should only receive refrigerant in the form of a superheated gas – NOT a cold liquid!

Here’s the bottom line: Turning the thermostat from COOL to OFF stops your AC from continuously sending cold refrigerant to your outside unit (where your compressor is located).

During a healthy operation, your compressor should only receive refrigerant in the form of a superheated gas—NOT a cold liquid.

Do you want more in-depth information about why your AC is freezing up in the first place? Come check out our blog, “Why Is My Air Conditioner Refrigerant Line Covered in Ice?”.

Step 2: Turn the fan setting to ON

By turning the fan on it forces your AC’s indoor fan to blow warm air non-stop over your AC’s frozen coils. This will help the ice thaw faster.

Tip: Do not turn your fan setting to AUTO. This setting only runs the blower motor during a cooling cycle. Furthermore, you just turned the thermostat from COOLING to OFF, so your AC won’t be going through any cooling cycles.

Your AC blower motor pulls in warm air from inside your home, and blows it over the refrigerant coils that make up the evaporator.

How long will it take for your AC unit to thaw?

It can take up to an 1 hour or 24 hours to unfreeze your air conditioner. It all depends on the extent of the ice buildup.

As you’re waiting for the unit to thaw, you should keep an eye out for:

An overflowing drain pan. If you can access your indoor AC unit, you may want to put some towels on the floor surrounding the unit. This will help prevent water damage if the melting ice overflows the drain pan and leaks onto the floor.

A clogged condensate drain. As the ice on your evaporator coil thaws, the water will drip into a condensate drain pan, and then flow outside via a condensate drain line (a white PVC pipe). Sometimes dirt picked up along the way can form a clog in that drain line and cause water to backup and overflow. If you think you have a clog, please follow these steps in this blog to clear the condensate drain line.

Step 3: Check your air filter and replace it if needed

The most common culprit behind a frozen AC is a dirty or clogged air filter, so check your air filter as you wait for the unit to thaw out.

Pro tip: Check your filter as soon as you turn the thermostat to OFF. The longer you wait, the more likely the ice will melt onto your air filter and create a dirty puddle.

If your air filter looks identical to the filter below, then change it out for a new filter immediately.

Believe it or not a thin layer of dust or dirt on your air filter can cause major AC problems, so change it out even if the filter isn’t quite as clogged as the one above.

A dirty air filter suffocates your air conditioner. Also when your air conditioner doesn’t get enough warm air flowing over your evaporator coil, the refrigerant inside will colder and colder. Remember: very cold refrigerant coils + moisture in the air = ice.

Do you need help finding your air filter? If so check out our blog, “Where Is My Air Conditioner Filter?”.

You replaced your dirty filter, so now what?

Since you just replaced a dirty filter you will continue to wait until your AC has completely thawed out. Once your AC is unfrozen go ahead and turn the AC back on and run the air normally, but keep a close eye on the unit for the next couple of days.

More than likely, the dirty filter was the problem, but to be sure that there isn’t another issue watch for any ice returning on the AC lines. If you notice any ice forming or notice other AC problems, call a professional to inspect and diagnose your unit.

Step 4: Don’t have a dirty filter? Call a professional right away.

A dirty air filter isn’t the only problem that can cause a frozen AC, but it’s the only problem that you can solve on your own!

If you checked your air filter and it is completely clean, you have a more serious AC problem regarding:

-A refrigerant leak

-Dirt on the evaporator coil

-A weak or bad blower motor

-Stuck or closed expansion valve

-Collapsed duct

Any other number of AC problems you see ice on your indoor or outdoor unit, it’s a clear sign that something’s wrong with your AC unit.

Please do not ignore this problem, or you’ll continuously deal with a frozen AC and you will end up paying over $3,000 for a damaged compressor.
