Coils and Condensers are the ‘Cool’ Part of Your AC System

Published on: May 16, 2012

Have you ever wondered how your air conditioning system cools the areas in your home or business? Three major parts of your system do all the work and they are the compressor, evaporator, and condenser. If any one of these components needs air conditioning service, you should make an appointment with a HVAC contractor to complete any air conditioning repairs or maintenance on your system.


An evaporator is the interior unit of your air conditioning system that contains the evaporator coil. Inside the coil, refrigerant flows through, draws the heat from your home, and dehumidifies the cool air. Aluminum fins surround the evaporator coil made of copper for insulation and conduction of the cool air. It is important that air conditioning service and maintenance include cleaning and replacing refrigerant when it is low. If the air conditioning repair includes refilling the refrigerant, be sure the technician uses one without CFCs.


The exterior condenser receives the warm air and removes it from the building. Additionally, the condenser coil and area surrounding it must remain free of dirt and debris. If air cannot flow freely, your system will be inefficient and will work twice as hard. If you want to avoid unnecessary air conditioning repair bills, make sure that it receives yearly tune ups and preventative maintenance.


Refrigerant moves through the evaporator and condenser coils by compressor, which is the pump. Air conditioning services for preventative maintenance on your system include cleaning and yearly tune ups. A dirty compressor wastes energy because your system works harder and inefficiently. Reduce and avoid the necessity for an air conditioning repair with yearly tune ups and maintenance.

Whether you need air conditioning service for a new energy efficient system or air conditioning repair on an existing system, choose a qualified HVAC contractor.
