On a hot day, there is nothing more frustrating than your a/c system refusing to cool. Whether your air conditioner is produced by Trane manufacturer or another well-known brand, an a/c maintenance service can help you to identify the problem with the unit and get it repaired or replaced. Here are several common a/c problems that lead to a lack of cooling in Edwardsville, IL.

Blocked Air Filters

The filters in an air conditioning unit remove dirt, dust, pollen, hair, and other indoor air pollutants from the air. Over time, these filters can become blocked with all the substances they filter out, leading to a lack of airflow through the system. Replacing the filters is one of the most common a/c repairs carried out by HVAC professionals.

Unclean Coils

If filters are not able to do their job properly, the condenser coils of an air conditioning unit can become dirty. When this occurs, the condenser cannot easily dissipate heat to the outside of your property, leading to a lack of cooling.

Not Enough Coolant

Coolant is the liquid that circulates through the coils of the evaporator, cooling the air that flows over it. Every so often, coolant levels need to be replenished. Leaks can cause coolant to disappear more quickly, which means it is always worth getting an HVAC professional to refill the coolant so they can check for leaks.

Defective Compressor

The compressor is the core part of an air conditioning system. It changes the volume of air, affecting its capacity to store heat, as part of the cooling process. Problems with the compressor can lead to your a/c not cooling, even when all the other parts are working well.

Thermostat Errors

The thermostat is the part of your air conditioning system that measures the temperature in the room. If the thermostat is faulty, the unit will stop producing cool air because it is getting a signal to say that the room is already cool enough. Electrical faults can cause thermostats to fail.

Underpowered Air Conditioner

Sometimes, the problem with your air conditioner is that it is simply too small and underpowered to cope with extremely high temperatures. This is most likely to be the case if you are using a small unit to cool a large home, or if the unit is very old. In this case, you will need to replace the a/c unit with one that is more appropriate for the space you need to cool.
