HVAC stands for Heating, Ventilation, and Air Conditioning. HVAC refers to the different systems used for moving air between indoor and outdoor areas, along with heating and cooling both residential and commercial buildings.

HVAC basics

The main purposes of a Heating, Ventilation and Air-Conditioning (HVAC) system are to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort.

First, there is a source of fresh air intake from the outside or from within the home. This process is called ventilation, and it happens in two different ways. Natural ventilation is present in most homes and refers to the way air typically moves in and out through windows, doors, vents, and other openings. This exchange of air is necessary to replenish oxygen, and to remove odors, carbon dioxide, and excessive moisture.

Mechanical ventilation uses a mechanical system ‐ the V in HVAC ‐ to move air in and out. In the past, there was plenty of natural ventilation in most homes from gaps and cracks in the construction along with opening and closing of doors. However, modern construction is creating homes that are far more tightly sealed so ventilation is becoming an increasingly important component in home HVAC systems. Once the air is brought in, it is drawn into an air handling unit where the work begins. Here, air is drawn through filters to remove dirt, dust, allergens, and other particles.

Next up, is comfort. Air is either sent to be heated or sent to be cooled and have excess humidity removed. Once the air is clean, fresh, and at a comfortable temperature, it is directed into the home. For central systems, this means moving through a network of ducts and registers to different rooms. For other systems, this usually means being directed right into the space.
