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

Published on: May 2, 2012

It is wise to learn about the cool part of your air conditioner while everything is working fine. When you need an air conditioner repair, you may be able to troubleshoot what the problem is. Of course, regular maintenance will keep your unit running at peak efficiency and lessen the number of repairs needed.

Your air conditioner cools the air by using coils. The coils are a series of pipes filled with a refrigerant. The refrigerant is stored in the compressor unit outside the house. When it leaves the compressor unit, it is hot. It cools somewhat on the way to the coils, located inside the blower unit. It is compressed by a series of nozzles, which super- cools it. The HVAC system draws in air through a filter. The filter captures debris and dust that would interfere with the coils and need air conditioner repair. The air is passed over the coils and two things happen. The first is condensation from the warm air against the cold pipes. This moisture flows down the drain to the outside of the house. The heat in the air passes into the cold refrigerant. This causes the temperature of the air to drop. This is how your air conditioner cools the air. By maintaining the system, you will not need an air conditioner repair as often as an unmaintained unit.

The heated refrigerant flows to the condenser coils outside. A fan works much the same as a car radiator. It blows air on the condenser coils to cool the refrigerant. Your air conditioner works very hard to cool and dehumidify the air you breathe. The most common complaint for an air conditioner repair is not getting cold air. Understanding and maintaining your coils will keep them working properly.
