How Central Air Conditioning Systems Work

Central air conditioning is a term used to describe the entire home air conditioning system. It sucks warm air inside your living spaces, passing through the evaporator, condenser, compressor, and expansion valve, and with the help of a specialized chemical called “refrigerant,” cold air will be blown back into your living spaces.

During maintenance, or in case your air conditioning system needs repairs, or when parts need to be replaced it’s helpful that you have a basic understanding of how your air conditioning system works.

There are two types of central air conditioners, the split system which has both an indoor and outdoor unit, and the packaged system which is a single outdoor unit recommended for those with limited space.

  1. Split system air conditioning: The outdoor unit contains the condenser coil, compressor, electrical components, and a fan. The evaporator coil is usually installed on top of the gas furnace inside the home. Air conditioning lines/pipes connect the inside and outside units. Refrigerant circulates through the indoor and outdoor units. A thermostat is used to control or set temperature.
  2. The Refrigeration Cycle: Using electricity as its power source, the refrigerant flows through a closed system of refrigerant lines that connect the outdoor unit to the indoor evaporator coil. Warm air and humidity from the inside are pulled into the ductwork. The refrigerant transitions from a low-pressure gas to a high-pressure liquid pumped from the exterior compressor coil to the interior evaporator coil as it absorbs heat and cools it down before pushing it through connecting ducts or vents and back inside your home. This cycle continues until you reach the desired temperature providing a consistent cooling.

Benefits of Central Air Conditioning System

  • Indoor comfort as it helps keep your home cool while reducing humidity levels during the warmer season.
  • Cleaner air – Air filters remove airborne particles such as dust and lint. Modern filters even feature sophisticated attributes that could remove microscopic pollutants
  • Almost noiseless operation – the compressor is typically on the outside unit which lowers the noise level whenever in use.
