43 HVAC Service Contractors in San Leandro, CA

San Leandro sits along the East Bay shoreline where marine breezes from the Pacific keep summer temperatures mild compared to inland areas, with average July highs around 73 F. However, the 2021 heat dome proved that even coastal communities can spike past 100 F, and inland neighborhoods regularly hit the upper 90s during heat events. With 65 contractors serving the area and an average rating of 3.6 stars across more than 10,000 reviews, HVAC service in San Leandro has become essential as homeowners replace gas furnaces with heat pumps driven by California decarbonization policy, install mini-splits in older homes never originally ducted for cooling, and address indoor air quality during wildfire season.

California requires HVAC contractors to hold a C-20 Warm-Air Heating, Ventilating, and Air-Conditioning Contractor license from the CSLB, ensuring baseline competency across the market. Homeowners in San Leandro can expect to pay between $71 and $190 for a service call or diagnostic, between $67 and $190 for a routine tune-up on a single system, and between $143 and $1,140 for standard repairs, with final costs depending on system age, complexity, and parts needed.
