HVAC Residential Contractors are individuals who start their own business fabricating, installing, maintaining, servicing, and repairing warm air heating systems, heat pumps, ventilating systems, and air conditioning systems. Contractors can work alone or hire employees to help operate the business.
In some states, including California, to become an HVAC Residential Contractor you must obtain a license and proper insurance. For HVAC Residential Contractors, the licensing classification is "C20 - Warm-Air Heating, Ventilating and Air-Conditioning Contractor." A warm-air heating, ventilating and air-conditioning contractor fabricates, installs, maintains, services and repairs warm-air heating systems and water heating heat pumps, complete with warm-air appliances; ventilating systems complete with blowers and plenum chambers; air-conditioning systems complete with air-conditioning unit; and the ducts, registers, flues, humidity and thermostatic controls, and air filters connected with any of these systems. This classification includes warm-air heating, ventilating and air-conditioning systems which utilize solar energy.
