HVAC stands for Heating, Ventilation, and Air Conditioning. It refers to the systems and technology used to regulate temperature, humidity, and air quality in buildings. HVAC systems are responsible for maintaining a comfortable indoor environment, providing clean air and controlling temperature and humidity to ensure the health and well-being of occupants. HVAC technicians install, repair, and maintain these systems, ensuring they are operating effectively and efficiently. The field of HVAC covers a wide range of products and technologies, including heating systems, air conditioning units, ventilation systems, and refrigeration systems.

HVAC (heating, ventilating, and air conditioning; also heating, ventilation, and air conditioning) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, (heating,ventilating and air-conditioning & Refrigeration) or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).
HVAC is important in the design of medium to large industrial and office buildings such as skyscrapers, onboard vessels, and in marine environments such as aquariums, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.
