Central Air Conditioning
Central AC is a cooling system that uses a refrigerant to absorb heat, making an area cooler. The central air conditioning unit cools and dehumidifies air before pushing it through a home's ductwork with a series of fans. These cooling units are typically combined with a furnace system.
- The ductwork system used by a central air conditioning unit can also distribute heat from a furnace.
- Works quickly to spread cool air through an entire home.
- The filter used in a central AC system can remove pollutants and allergens from the air.
Air conditioners manufactured in the 1970's use 30-50% more energy than today's models. Efficiency of AC units is measured in SEER (seasonal energy efficiency ratio). Older systems typically have ratings of 6 SEER or less, while central air conditioning units made today must have a minimum of 13 SEER. The higher SEER rating, the more energy savings an AC unit will provide over the course of its lifetime.
