Following are some of the common reasons behind the problem for which you are here; read all of them and troubleshoot accordingly.
Air Conditioner Clogged Filter
Filters that are unclean or clogged are another prevalent issue with AC systems. Throughout the year, these filters trap hair, lint, dust, and pollen.
If they are not replaced on a regular basis, they do not take long to refill. In this instance, the air cannot flow correctly into the house, and your air conditioner may be shut off due to a lack of air.
The internal temperature rises when the air conditioning fails to function properly.
Clogged filters can also cause parts to wear out faster than they should if they are left for an extended period.
It can also erode the evaporator coil and condenser, causing a much worse issue.
The filters should be replaced every three months, in addition to periodic cleaning. If you have pets, you may need to replace them more frequently.
You should be able to replace the room air filter on your own. However, if you are confused about which filter to use, an AC professional can assist you.
Air Conditioner Faulty Condenser or Evaporator Coil
The above filters do their best to keep the coils clean and functioning properly, but the coils do wear down with time.
Because of the persistent humidity, your indoor evaporator may be susceptible to mold and mildew.
Coils can also freeze if the system’s refrigerant level is low.
Problems with the coils will result in major air conditioning failures and should be investigated as soon as possible by a plumbing professional. Here is a guide on Cleaning air conditioner coils with vinegar.
Over time, the capacitor may also wear out. Check your air conditioner as well if it is not blowing cold air for any other reason.
Air Conditioner Thermostat
If the power supply is working properly but the air conditioner is still not blowing cold air, the thermostat on the unit may not be set to the proper temperature.
Turn the knob all the way down or move the buttons all the way to the bottom to see if the unit works.
If possible, double-check that all thermostat cables and, if required, batteries are correctly attached.
Leakage of Refrigerant
Between the exterior and inside air conditioning units, the refrigerant is cycled, compressed, and expanded. It will never run out, therefore there is no need to refill or top it up.
However, if a refrigerant leak happens, it will not be enough to absorb the heat properly. As a result, you will notice a decrease in the amount of chilly air.
If you hear a hissing hiss while using the air conditioner or if it freezes, this is a sign of a problem.
