The Basics of HVAC

HVAC stands for heating, ventilation, and air conditioning. It’s the system of outdoor and indoor units, ducts, furnaces, and more that work to provide your home with a comfortable temperature and high air quality. This video explains the basics of how the air conditioning part of HVAC systems work.

Air conditioning systems are made up of many parts, but the main ones are the evaporator and the condenser. The evaporator sits on the inside of the property and the condenser is on the outside. They are both heat exchangers that remove heat from the air or expel it into the outdoor air.

The compressor is another key element that circulates refrigerant throughout the AC system. Refrigerant is a substance that can change from a liquid to a gas very easily, making it easy to move between the pipes of the air conditioner.

Warm air is blown over the refrigerant-filled pipes, causing the refrigerant to turn into gas. The evaporated (gas) refrigerant carries heat out of the home. Once the refrigerant is carried out of the home, it goes through the compressor and then into the condenser, where it is cooled back into a liquid. The process starts all over.
