If you’ve noticed that your unit isn’t keeping your home cool enough, or it’s not cooling at all, then you’ve got an issue on your hands. Here are some of the most common AC problems that we encounter, and what you can do to get your system back to its best.
Leaking Refrigerant: Your refrigerant is responsible for pulling heat out of the air as it transitions from a liquid to a gas. If your coils are leaking refrigerant, then your AC unit will lose its cooling power. We’ll identify the source of a refrigerant leak, fix the leak, and top off your refrigerant lines with the appropriate amount of fluid, so that your system is up and running once again.
Failing Electronic Controls/Thermostat: A faulty thermostat can cause your AC unit to work overtime, or it may mean that your unit won’t turn on at all, even when your space is hotter than the trigger point on your thermostat. You may also have an electrical problem that exists between your thermostat and the unit itself — which will likely mean that your unit won’t start at all. We can assess the electrical components of your air conditioner system, and we’ll fix any issues along the line.
Poor AC Unit Drainage: Your AC unit will naturally collect some condensation as it cools the air around the evaporator coils. Fortunately, air conditioner units are built to handle condensation, and they’ll drain condensation appropriately, as long as the coil doesn’t freeze over, and the drainage area remains clean. Unfortunately, your AC unit drain line can become clogged over time which can eventually cause your coils to become dirty and freeze over (which will eventually damage the unit).
Dirty Vent Registers: The vent registers throughout your home can become gunked up with dust and debris, hindering the efficiency of your system. If you have dirty vent registers, then your AC unit may be working overtime without cooling your thermostat enough to shut the system down. Fortunately, this is a pretty simple fix. Just pull off those registers, and make sure they’re clean (a quick vacuuming or rinse should do the trick. Just be sure to dry your registers if you rinse them, since they will rust).
Dirty or Poorly Installed Ductwork: Similarly, your ductwork may be clogged up with debris, dust, or even nests from various pests (it happens!). If this is the case, you’ll have to have your air ducts inspected and cleaned.
You may also have ductwork that is poorly installed, or duct work that has moved, creating gaps between various duct sections. Again, have your air ducts inspected, and be sure to have any gaps resealed.
Broken Fan: Your AC unit relies on fans to blow cool air into your home, while pushing hot air away from the outdoor component of your unit. If either of these fans break, your unit won’t work as it should. Fortunately, a broken fan is fairly simple to replace, and you won’t have to get an entirely new unit. If you notice that your unit is cooling poorly, or not cooling at all, a fan may be to blame.
Frozen Evaporator Coils: As we mentioned, your evaporator coils are liable to freeze over as they cool the air around the coil. When this happens, your refrigerant can back up and create problems for your AC unit. It’s best to avoid frozen evaporator coils if possible. Coils can often freeze over if your AC unit is constantly on (which may be an indication of another problem with the unit). Don’t let your AC unit run if you notice that the coil is frozen over. Instead, schedule an appointment to investigate the problem, before it turns into a costlier issue.
Broken Compressor: Your compressor is responsible for compressing gaseous refrigerant back into a liquid. If you have a broken compressor, you have a serious problem on your hands, and it’s likely that you’ll have to replace the entire AC unit, since compressor repairs are often as expensive as the unit itself. Again, you’ll notice that your AC unit is no longer cooling your spaces if the compressor is down.
Why is my AC unit constantly running?
Your unit may be running constantly for a variety of reasons, and it should be assessed, regardless of the issue at hand. Your unit can work overtime if you have a poorly insulated home, an undersized AC unit, or a unit that isn’t operating as it should. Your unit can also be out of refrigerant, it may have a broken fan, or the compressor may be shot. You may have an issue with your thermostat as well. If you notice that your AC unit won’t shut off, then you should have us over to assess the problem, before your unit’s evaporator coils freeze over, creating more of an issue.
Ideally, how often should my unit run on a hot day?
Ideally speaking, your AC unit should only run two or three times per hour during the heat of the day. Your unit should click on for 10 to 15 minutes, and then it should turn off after the cooling cycle is complete. If your unit is running more often or for longer durations than the aforementioned times, then your unit is inefficient, and you could be wasting precious energy and hard-earned dollars when your energy bill comes in the mail.
How long do air conditioner units last?
While modern air conditioner units are lasting longer and longer, they will eventually fail and need to be replaced. You can expect your unit to last between ten and fifteen years, if it is properly maintained and repaired over its lifetime.
Why isn’t my AC unit cooling my home?
It may be difficult to assess why your AC unit no longer cools your home, since several issues could be the source of this problem. When you call us to check out a poorly operating AC unit, we’ll look for a variety of source issues. You may have a problem with your duct work. You may have an air filter that is gunked up with dust and debris. Your unit may be leaking refrigerant. The thermometer may be inoperational. Your unit’s fan may be broken. The list goes on and on. Again, we’ll take a look at your entire system, and we’ll pinpoint the issue at hand.
My unit tripped the electrical breaker, how do I get it started again?
AC units commonly trip their electrical breakers, especially if they’re constantly working throughout the heat of the summer. Be sure to turn off your unit at your thermostat. Then find the breaker for your unit, and flip it back on. Let the system rest for 30 minutes. Then turn your thermostat to cooling mode once again.
How can I defrost a frozen evaporator coil?
If you have a frozen evaporator coil, its best to turn off your AC unit until the coil is completely defrosted. Simply turn off your system at the thermostat. Wait til your coil is completely defrosted (it could be several hours until your unit is defrosted). Then turn your unit on to cool mode once again. If your evaporator coil continues to freeze over, you may have another problem on your hands.
