No. Heating, ventilation and air conditioning (HVAC) is decidedly not the same as plumbing, which deals with delivery of potable water into and waste water and effluent away from a building or home, among other tasks. There is some overlapping of skills and equipment.

What Does HVAC Stand For? HVAC stands for heating, ventilation, and air conditioning. It refers to the systems that regulate and move heated and cooled air throughout residential and commercial buildings, from homes to offices to indoor stadiums.

HVAC Working Principles Air is forced through that heat and redistributed throughout the building to increase the ambient temperature. When cooling is necessary, warm air is forced over the cooling system's refrigerant coil. Heat is naturally absorbed by the refrigerant, leaving behind cold air.

The main purposes of a Heating, Ventilation and Air-Conditioning (HVAC) system are to help maintain good indoor air quality (IAQ) through adequate ventilation with filtration and provide thermal comfort. HVAC systems are among the largest energy consumers in schools.
