Is Your AC Losing its Cool?

November 6, 2017

We know air conditioning is one of the most important concepts to your comfort and peace of mind. If your AC is not cooling properly, the reason could be as simple as dirty coils. Clean coils are extremely important for the proper functioning of an air conditioning system. Even if 1/100th of an inch of dust collects on the AC’s condenser coil, it loses 5% of its efficiency. Our St. Louis HVAC technicians explain how dirty coils could be causing your AC to under-perform. The Importance of Air Conditioning Coils There are two AC coils which are very important for the proper operation of the system. The evaporator coil is responsible for absorbing the heat and humidity from the space. The condenser coil releases the heat absorbed from the inner space, outside the building.

This can reduce its capacity to work properly. The Way in Which an Air Conditioner Works In order to understand how dirty coils reduce the cooling ability of the AC, it is advisable to know how an air...
