Hiring an HVAC Contractor in Colorado
Buildermuse currently lists 10 hvac contractors in Colorado, averaging 5.0 stars across 11,935 verified Google reviews. That is an unusually strong field — when nearly every firm clears 4.8 stars, response time and availability become the real differentiators, so call two or three rather than only the top result. Most of the crews above operate out of Denver, Colorado Springs, and Commerce City.
Colorado does not require a state-level general contractor license. Licensing is handled by individual cities and counties. Denver, Colorado Springs, and Aurora each have their own licensing requirements. State-level licenses exist for electrical and plumbing only. With no statewide license for this work, checking city and county requirements — plus active insurance — falls on you as the hiring party.
Labor is the biggest line item on most bids, and the Colorado market sets the floor: construction workers here average $37.92 an hour — about $78,884 a year — across 189,477 workers statewide, per Bureau of Labor Statistics data. Use that figure as a sanity check when comparing quotes — a bid priced far below market labor rates usually means subcontracted or uninsured crews.
