How does Air Conditioning actually work?

It's that time of year again, when many people are feeling grateful for central air conditioning. It's great to have a cool retreat when it's hot outside, but how does that air conditioner actually work? Today, we'll explore how a typical central air system in a residential home cools the air.

1. The typical central air conditioning system is a split system, with an outdoor component, the compressor bearing unit, and an indoor component, the coil which is usually installed on top of the furnace. 
2. The outdoor compressor pumps refrigerant through the system which gathers heat and humidity from inside the house. 
3. This warm air is blown over the cool indoor coils, cooling the air and transferring the heat to the coils. 
4. The cooled air is pumped back through the home and the heat that has transferred to the coil is pumped outside. 

Did you know...

• In addition to keeping your home cool, this method of air conditioning also removed excess moisture from the air and reduces the humidity in your home? 
• Your air conditioner actually cleans the air in your home? As the air is pulled through the return air ducts, it goes through a filter, which removes dust, lint and microscopic pollutants.
