HVAC  Short for heating, ventilating, and air conditioning),the system is used to provide heating and cooling services for residential, commercial or industrial buildings and the people working inside buildings with “conditioned” air so that they will have a comfortable and safe work environment. HVAC systems have become the required industry standard for construction of new buildings.
