Air conditioning, heating, indoor air quality, duct services, commercial HVAC, and electrical trusted experts serving Fontana homeowners and businesses since 1949.

Sitting along the I 10 and I 15 corridors, Fontana sees plenty of heat and plenty of dust kicked up by heavy truck traffic, and your HVAC system feels both.

Sanborn's licensed electricians handle everything from panel upgrades to whole home rewiring for Fontana homeowners. Whether you need a new EV charger, a safety inspection, or an emergency repair, our team responds quickly and works to code across both Fontana's older neighborhoods and its rapidly growing newer subdivisions.
From retail space along Sierra Avenue to the warehouse and distribution facilities that have come to define much of Fontana's economy, Sanborn's delivers the HVAC reliability Fontana businesses depend on. We work around your schedule to minimize downtime and keep your team and customers comfortable all year.
Leaky or dirty ducts force your HVAC system to work harder, and Fontana's heavy truck traffic and ongoing construction mean more airborne dust finds its way into ductwork than in quieter parts of the Inland Empire. Sanborn's duct specialists locate and fix leaks, clear buildup, and restore airflow so your whole system performs the way it should.
Fontana residents deal with seasonal allergens, wildfire smoke, and a higher than average amount of particulate pollution thanks to the dense truck traffic moving through the area's logistics corridors. Most homes just recirculate that same air, complete with dust, pet dander, mold spores, and VOCs. Sanborn's indoor air quality solutions target these issues at the source.
Fontana winters are mild, but older homes built during the city's steel mill era often have outdated heating systems that haven't been touched in decades. Sanborn's technicians respond fast to heating emergencies and diagnose the exact issue before quoting any work.
Fontana summers run hot, often among the warmer spots in the Inland Empire, and a failed AC during a heat wave isn't something to put off. Sanborn's same day service gets you back to cool fast, and we carry parts for all major brands on our trucks so most repairs are finished on the first visit.
Serving the Inland Empire since 1949 over 75 years as a locally rooted, family-run business that treats every customer like a neighbor.
Every technician carries NATE certification the gold standard for HVAC competency plus ongoing manufacturer training on the latest systems.
