The last thing you want on a hot summer day is your AC not cooling your house. Air conditioners have become an essential part of every household. Apart from shielding us from extreme heat, they also provide other benefits like low humidity, better air quality, and better smell.
When ACs are not working properly, they take away with them not only a better lifestyle but also leave you feeling frustrated and sweaty.
Let’s discuss the reasons why your air conditioner is not working properly and how you can fix them.
Your Thermostat Is Set To “ON”
When you notice your AC is not working, your first step should be to check your thermostat. Sometimes the thermostat is set to “on” only, which makes it run the fan 24/7 without cooling the air. It might blow out cold air sometimes and lukewarm air other times. To fix this problem, make sure the thermostat is set to “Auto” or “Cool.”
If you notice that your air conditioner is still not blowing out cold air from the vent, even after changing the thermostat settings, then the problem might be with your thermostat wiring. Fixing this problem should be left to the professionals.
Your AC’s Air Filters Are Dirty
Dirty air filters are the number one cause of HVAC system failure, and they should be your second stop to see what’s wrong with your AC.
Air filters are important to maintain the flow of the air. Expanded air is brought back to them to be purified. This air is then conditioned and is distributed back. Clogged and dirty filters restrict the circulation of air and reduce the cooling capacity of the system. They put pressure on the motor and also freeze the evaporator coil, which blocks any cool air trying to get out.
Air filters should regularly be cleaned. If the pollutants have damaged them, consider replacing them from a local hardware store.
Your Condenser Coils Are Dirty
Dirt is no friend of air conditioners, and this should be kept in mind while looking for system faults.
Air conditioners work by pulling the hot air from inside, absorbing its heat (through the evaporator), and radiating it out through the condenser. However, if the condenser coils are dirty and clogged with debris, the heat is unable to dissipate outside. This decreases the efficiency of the system and makes it work even harder. If the coils are dirty, the system will never be cold and will not be able to cool the room as well.
Your AC’s Refrigerant Is Leaking
Refrigerants or coolants are essential to cool the air. They are circulating in the evaporator coil and cool the air that’s flowing over it. Usually, the refrigerant levels never drop, but if you hear a hissing noise and you see your conditioner is not cooling properly, then there might be a refrigerant leak. If this is the case, turn your AC off immediately and call a professional to fix it.
Your Compressor Is Not Working
Compressors are the heart of air conditioner machines. They compress the coolant and keep them flowing through the evaporator coil and condenser. If the compressor motor is damaged, the cycle is hindered, which in turn stops the AC from cooling the air. This problem should also be tackled by an expert only.
Air conditioners are essential to keep the air quality indoors fresh and healthy. Any faults in the system can leave you irritated and annoyed, especially when it is 100 degrees outside.
