How Central Air Conditioning Systems Work

The typical central air conditioning system is a split system, with an outdoor air conditioning, or “compressor-bearing unit” (commonly known as a condenser) and an indoor coil (also known as an evaporator), which is usually installed on top of the furnace in the home.


Central air conditioning helps keep your home cool and reduces humidity levels.

Cleaner air – As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply duct-work that carries it back to other rooms in the house.

Quieter operation – Because the compressor-bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.

We’ll discuss this type of heat somewhat vaguely, because these systems can vary from one extreme to another. It would take up the size of a large book to describe these types of systems you wanted to get into the finer details. Older systems (50 years old) that use radiators may be hot water or steam. Some people don’t know the difference, and the differences can be huge.
