Understanding some of the most typical AC issues can keep you better prepared when they
eventually strike. In this comprehensive guide, we lay out the 11 most likely offenders for your ac
system not cooling.
The Filters Are Obstructed
Possibly the most typical cause of air conditioner problems is clogged-up filters. Dirt, family pet
hair, pollen, and dust can clog your filters.
When filters get clogged, they start to limit the circulation of air through your a/c. The result is that
the a/c doesn’t cool your indoor air effectively. Blocked filters can likewise disrupt the functioning of
your system’s indoor evaporator coil and outside condenser system.
The very best way to prevent concerns with clogged-up filters is to clean them regularly and alter
them when needed. We advise changing them every 3 months. For those with animals, it might be
essential to change filters more frequently.
The Refrigerant Is Leaking or Low
Air conditioning systems use refrigerant, a chemical that moves heat from the indoor area and
moves it outdoors. There are many types of refrigerants, consisting of Puron and the widely known,
phased-out Freon, that cool the air in your a/c system. When the refrigerant level is low, your air
conditioning may have problems cooling the air in your house.
There are 2 possible reasons your air conditioning’s refrigerant level is too low. It could be that the

important that you look for professional air conditioner repair right away. A refrigerant leak can
trigger refrigerant poisoning, although unusual, and harm the environment.

coil can also experience issues in time. (By the way, setting up a UV light can help in reducing the
gunk that builds up in the indoor evaporator coil. It also enhances air quality.).
Coils tend to get dirty with time because they remain humid and it’s easy for mildew and mold to
build up. This can negatively impact their operations. Coils can also freeze over and stop working,
particularly when there’s not enough refrigerant in the system.

other animals have settled in their attic and harmed the ductwork.

mistakenly damage ductwork in the attic.
These reasons are what a lot frequently trigger air leakages causing a hot home. Air ducts
distribute the conditioned air throughout your house. If they have leakages, it will minimize the
cooling in your home.

refrigerant between the indoor and the outside units. When the compressor gets harmed, the
entire system can’t cool your indoor air successfully.
Other smaller and more economical electrical parts may have spoiled which can appear like a
compressor failure. For instance, you might require to change the capacitor or other hard-start
the device which keeps the compressor going.

your compressor if your condensate drain has actually gotten blocked. This avoids water leaks in
Problems with an AC compressor can best be resolved by replacing it. The greatest problem is
that compressors can be exceptionally pricey. Unless you have a guarantee on this part, you may
want to change the entire outside unit.
Issues with the Outside Fan Motor Could Be the Offender

from your home and releasing it outside.
Unfortunately, the fan can develop issues and cause your air conditioner compressor to get too hot.
The best option for this problem is to get an expert in air conditioning troubleshooting to repair it. If
your fan motor spoils, your fan won’t run and your air conditioning system will overheat and close
down within minutes.
There’s an issue with the Thermostat
Your central air conditioning’s thermostat determines the temperature level of your indoor air and
adjusts it to your preference. When there’s a problem with your thermostat, it can result in problems
with your a/c’s general functioning. Sometimes, thermostats stop working, and replacement is a
