HVAC/R Commercial Contractors are individuals who start their own business fabricating, installing, maintaining, servicing, and repairing HVAC/R systems in commercial and industrial settings. They work alone or hire employees to help operate the business.
In some states, including California, to become a HVAC/R Commercial Contractor you must obtain a license and proper insurance. Commercial Contractors are considered within a specialized building trade and are required to hold a Class C certificate in at least one of four specialties based on the work they complete. The C-4 Boiler, Hot-Water Heating and Steam Fitting certification is designed for contractors who install, service, and repair power boiler installations, hot-water heating systems, and steam fitting. The C-20 Warm-Air Heating, Ventilating and Air-Conditioning contractor is one that fabricates, installs, maintains, services, and repairs warm-air heating, ventilation, and air-conditioning systems, including those which utilize solar power. The third classification specialty is C-38 Refrigeration. A refrigeration contractor constructs, fabricates, erects, installs, maintains, services, and repairs refrigerators, refrigerated rooms, and systems and thermostatic controls for the control of air, liquid and/or gas temperatures below fifty degrees Fahrenheit. The final classification for HVAC contractors is the C-46 Solar which is a specialty in installing, modifying, maintaining, and repairing thermal and photovoltaic solar energy systems.
