The ‘Cool’ Part of Your AC. The Coils and CondensersPublished on: May 2, 2012
Your air conditioner is a fascinating machine. It heats, cools and dehumidifies the air, keeping you and your family comfortable. During your next air conditioning tune-up, ask the technician to explain how the system works to keep your house cool. To help avoid ac repair, it is important to understand how your coils and condensers work to keep you cool.
The air conditioner draws inside air through a filter and sends it flowing over the evaporator coils. The coils are filled with cold refrigerant. The mixture of hot and cold causes the moisture in the air to condense and form drops. These drops flow into the drain pan and into the drain line. If the line is clogged with algae or mold, it will back up into the house. An ac repair technician will clear the line and advise you to pour a cup of bleach every month into it to keep it clear. Make sure an access port is installed as part of the air conditioning installation.
The cooled and dehumidified air flows into the ducting system to be delivered to the house. The refrigerant in the evaporator coils picks up the heat from the air and carries it to the condenser coils. A fan runs to cool the condenser coils the same way a car radiator fan works. With regular maintenance, an ac repair in the condenser should be minimal. Without regular maintenance of the coils and condenser units, you will need a new air conditioning installation.
A number of products online are touted to clean coils and condensing units to save you money. It is better to have an ac repair company perform the maintenance on a regular basis. The technician can also help you select a high-efficiency unit for your next air conditioning installation.
