Why Is Your AC Not Cooling After Changing the Filter?

If you’ve just changed your air conditioning filter during ductless air conditioning service in Lawndale, CA, but the AC still isn’t cooling, there are a few things that could be wrong with your system. While there are several reasons why this might happen, a few common causes are worth checking for.

Reasons Behind Your AC Not Cooling:

If, after the successful ductless air conditioning installation in Los Angeles, your unit defies to work properly, there may be some problems that the changing filter couldn’t help. Some of these common reasons are:

Faulty Thermostat

If you’re having trouble cooling your home, it could be because the thermostat is not working correctly. The thermostat is the brain of an AC unit and controls all of its functions. If you have replaced your filter and still cannot get cool air, there may be something wrong with your thermostat.

A Malfunctioning Compressor

Most likely the AC motor is not functioning properly. The compressor, condenser fan motor, and blower may connect to the same circuit board. If any of these components fail, they can cause problems with the other parts on that circuit.

If there seems to be sufficient voltage at each location, then one possible solution would be replacing an old capacitor with a new one from an electronics store.

Low Refrigerant Levels

If your AC is not cooling after changing the filter, it may be due to low refrigerant levels. If the level of refrigerant in the system drops below the minimum amount required, it will not be able to deliver enough cooling to your home or office. This can cause your air conditioner to stop working, leading to high energy bills and uncomfortable indoor temperatures.

If your AC was correctly charged at ductless air conditioning installation in Los Angeles and there has not been a noticeable difference in the power usage since then, low refrigerant levels could be to blame. Lack of refrigerant could also mean something else entirely. It could be a faulty thermostat, a malfunctioning condenser fan motor, or a compressor.

Frozen Evaporator Coil

If your AC is not cooling, this could be due to a frozen evaporator coil. The evaporator coil is the part of your air conditioning system that absorbs heat inside your house and releases it outside. A frozen evaporator coil can cause air conditioning problems such as:

  1. Noisy operation.
  2. The airflow that’s uneven or nonexistent in some rooms.
  3. Low humidity levels with no condensation on windows or walls.

Clogged Condensate Drain

You may have a clogged condensate drain. The condensate drain is a tube that carries water from the air conditioner to the outside. If this tube becomes clogged, water will not flow out of the unit and can cause damage to your compressor and other parts of your AC system designed to remove moisture from the air.
