Seasonal Tune-Ups
Skipped tune-ups are the number one cause of mid-season failures. A Fontana seasonal tune-up catches worn capacitors, dirty coils, and weak igniters before the weather tests them. Plans available — call (877) 317-0473.

A seasonal tune-up catches the $150 problem before it becomes the $1,500 breakdown. Our Fontana maintenance visits cover cleaning, refrigerant and electrical checks, airflow testing, and safety controls — for AC in spring and furnaces in fall.
Heat Pump Installation & Repair
Is your heat pump running constantly, icing up, or blowing lukewarm air? Our Fontana heat pump techs diagnose refrigerant, reversing valve, defrost control, and airflow issues — then fix them right.
Thermostat Installation & Repair
Upgrading to a smart thermostat in Fontana? We match the thermostat to your system type and Wi-Fi setup, wire it cleanly, and configure staging and recovery so comfort does not suffer. Call (877) 317-0473.

Built for Fontana climate
California HVAC is a two-front battle: relentless summer heat that runs air conditioners for months, and wildfire smoke season that turns indoor air quality into a health issue. In Fontana, our network sizes AC systems for real peak loads — not averages — and pairs them with high-filtration options and sealed ductwork so smoke stays outside where it belongs. Heat plus smoke is the local reality; your system should be built for both.
The cheapest quote is rarely the cheapest system. In Fontana, proper installation — real load calculation, correct refrigerant charge, sealed ductwork — is what delivers the full 12–15 year equipment lifespan. 2026 ranges: repairs from $350–$800 for AC; replacements $3,500–$12,000.
