What is Heating Ventilation and Air Conditioning - HVAC

HVAC is a commonly-used acronym that stands for Heating, Ventilation and Air Conditioning. The term encompasses the entire range of interior air quality controls in homes and in corporate buildings. These three closely related systems are important for keeping home and work environments comfortable and healthy.

Heating

Heating is an essential feature of any building in a temperate climate as well as in many subtropical regions. HVAC professionals classify heating systems into two categories: central and local. Central heating options include steam or hot water radiators as well as forced air and radiant heating systems. Local heating options include electric or gas heaters and standalone stoves that burn wood, corn or other fuels. Most modern structures use central heating. This type of heating provides more consistent temperatures throughout a building.

Ventilation

Ventilation systems are much less obvious than heating systems and can often be integrated to use the same ductwork. A home or business's ventilation system includes fans and other devices that move stagnant air out of the home, bringing in fresh air. Good ventilation keeps the interior of the home healthy. It also reduces the risk of mold and mildew growth in hidden spaces, improving air quality. This is especially important for people with respiratory problems like asthma or allergies.

Air Conditioning

Air conditioning systems are found in most climates with hot summers. They may not be required in regions where the summer temperatures never rise to dangerous levels. Like heating, air conditioners can be either local or central. Central air conditioning usually uses the same ductwork and fans required by forced air central heating systems. Local air conditioning involves portable, window or wall units that can cool only one or two rooms at a time.

Maintenance

No HVAC system can run forever by itself. All heating, cooling and air conditioning systems need regular maintenance by trained professionals to work properly. Ducts and fans must be cleaned regularly. Air conditioners need periodic recharging with new coolant to keep the air temperature comfortable. Without this care, dust build-up can reduce system efficiency. Poor maintenance can also encourage mold growth in ductwork and cause parts to fail more readily.

The best way for business and homeowners to keep their HVAC systems in good condition is to hire a qualified professional to perform maintenance at least once a year.
