Do HVAC contractors need a license in Nevada?
Yes. In Nevada, anyone acting as a contractor for refrigeration or air-conditioning work needs an active Nevada contractor’s license in that specialty, and a general building contractor may not do refrigeration and air-conditioning specialty work without it. The State Contractors’ Board’s regulation designates refrigeration and air-conditioning as classification C-21; heating, evaporative cooling and air circulation without refrigeration is subclassification C-1f. Small repair or maintenance work under $1,000 is exempt from the contractors’ law, but not if it is the type of work a refrigeration, heating or air-conditioning contractor performs. This is NRS 624.700, 624.215, 624.031; NAC 624.380.
