When most homeowners need HVAC repair services in Suffolk County NY, they find a local company with good reviews, BBB ratings, and ask friends and family for referrals. This is a good way to get a dependable and honest service. However, if you want to take better care of your air conditioning, it is a good idea to understand how it works. Here is basic information on how cooling systems operate.

Heat Removal

Explainthatstuff.com offers a good description about air conditioning principles. For example, cold air is not produced. Instead, a typical air conditioning system (installed by your local HVAC repair company) removes warm air from inside your home and places it outdoors. Why does this cool?

In reality, cold does not exist. It is just a comparison of heat levels. For instance, the less heat you have in an area, the colder it feels to you. Cold is better explained as “absence of heat.”

Evaporating Gas Cools

Stick your hand under some running water. Now wave it in the air or stand in a breeze. Your hand feels cool because the water turns into a gas as it evaporates on your hand and this removes the heat. An AC unit removes heat with a special liquid (which has a low boiling point) called a refrigerant.

A common AC unit has a compressor, evaporator coils, condenser coils, and tubing. The compressor compresses and pumps refrigerant to the evaporator coils, where it boils and turns into a gas. The gas leaves the evaporator coils and goes to the condenser coils. A fan blows the heat from the condenser coils condensing the gas back into a liquid, and the cycle repeats over and over.

Lessons to Learn

Once you understand how your ac works, you know the importance of cleaning coils and changing filters. This can help you avoid many HVAC repair bills in Suffolk County NY.
