Built for Fontana's heat

Fontana runs hotter and longer than most of Southern California. Systems here spend months at high duty cycles, and attic-mounted equipment and ductwork bake at temperatures far above the outdoor reading.

That means sizing and duct condition matter more here than in milder coastal cities. We measure the home, check return-air capacity and duct integrity, and specify equipment that can actually hold setpoint in August — not just on paper.

Replacement done properly

A correct changeout includes right-sized equipment, a matched indoor coil, a clean line set or new one where needed, verified refrigerant charge, adequate return air, sealed and supported ductwork, proper electrical and disconnect, and permitting where required.

Skip any of those and the system underperforms and dies early — regardless of what brand is on the box.

Repairs when repair makes sense

Capacitors, contactors, blower motors, control boards, condensate drains, refrigerant leaks and thermostat faults are routine work. We diagnose before quoting so you pay for the failure you actually have.

If the system is 15+ years old, running R-22, or facing a compressor failure, we'll show you the repair-versus-replace math rather than defaulting to the bigger sale.

Fair pricing across the Inland Empire

Complete HVAC replacement options run up to $9,995 depending on size, efficiency, ductwork, electrical, permitting and complexity. Estimates are free and carry no obligation.

If you already have a quote from another contractor, bring it — we'll tell you honestly whether the scope and price are reasonable.
