18 AC Installation Contractors in Pomona, CA

Pomona sits deep in the Inland Empire, far enough from the coast to miss the Pacific cooling effect that moderates Los Angeles and Orange County. Summer highs regularly push toward 97 F, with more than 85 days above 90 F and at least 20 days surpassing 100 F. The dry desert air, hovering around 28% humidity in summer, makes cooling systems work efficiently but places real demands on equipment capacity. Winters stay mild, dipping to around 37 F, which keeps heating relevant from November through February. Five licensed contractors serve the Pomona area, earning an average rating of 3.9 across 45 reviews, with only one offering round-the-clock service. That gap between demand and availability shapes every conversation about AC installation in Pomona.

Pricing reflects both system type and installation complexity. A window unit runs $162 to $756, while a ductless mini-split for a single zone costs $2,160 to $8,640. Central AC replacement using existing ductwork ranges from $3,780 to $12,960. California law requires HVAC contractors to hold a C-20 Warm-Air Heating, Ventilating, and Air-Conditioning Contractor license from the Contractors State License Board, a credential that verifies they meet baseline competency for safely installing and servicing cooling equipment in this demanding climate.
