Our furnace was short cycling all night. They showed me the cracked ignitor and gave me the price before touching anything. Best AC and heating repair guys in San Dimas, hands down.

Great tune-up. They caught a rusted-out drain pan before it flooded my hallway. Twenty minutes of prevention saved me a ceiling.

San Dimas HVAC Questions & Answers

Do you offer same day AC repair in San Dimas?
Yes. Same day AC repair in San Dimas is available most days, and emergency AC repair is dispatched 24/7 including nights, weekends and holidays. Call (888) 380-4427 for the next open window.
How fast can a technician reach San Dimas?
Typical arrival for San Dimas and nearby communities such as San Fernando, San Diego, San Francisco, San Clemente, San Gabriel, San Carlos is 2 to 4 hours for emergencies, and a same-day or next-day window for standard AC service and heating repair.
How much does AC repair in San Dimas cost?
Common repairs in San Dimas such as a capacitor, contactor, ignitor, flame sensor or thermostat usually run $150 to $450 installed. Blower motors, evaporator coils and AC compressor repair cost more. You approve a flat-rate price before we start.
My AC is not blowing cold air in San Dimas. What should I check first?
Check three things: the air filter, since a clogged filter chokes airflow; the outdoor unit, clearing debris and confirming the fan spins; and the breaker. If the indoor coil is iced over, set the system to FAN ONLY for one to two hours to thaw, then call us, because ice means low refrigerant or restricted airflow.
I have no heat in San Dimas. Is that an emergency?
If indoor temperatures are falling below the mid 50s Fahrenheit, or there are infants, seniors or anyone with a medical condition in the home, treat it as an emergency. We run 24 hour heating repair in San Dimas year-round. If you smell gas, leave the house first, call your gas utility, then call us.
Do you repair heat pumps in San Dimas?
Yes. Heat pump repair in San Dimas covers reversing valves, defrost boards, low charge, auxiliary heat strips, inverter mini-splits and cold-climate heat pumps.
Why is my furnace short cycling in San Dimas?
The most common causes are a dirty filter, a failing flame sensor, a blocked flue or a limit switch tripping from overheating. Short cycling wastes energy and can crack a heat exchanger, so it should be diagnosed quickly.
Do you offer AC tune-ups and furnace tune-ups in San Dimas?
Yes. Seasonal maintenance is the cheapest HVAC you will ever buy. An AC tune-up in spring and a furnace tune-up in fall prevents the majority of emergency breakdowns we see in San Dimas.
Are you licensed and insured?
Yes. Licensed, insured, EPA 608 certified and background-checked, with permits pulled where required.
Which brands do you service in San Dimas?
All major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, American Standard, Bryant, Amana, Daikin, Mitsubishi, Fujitsu, Payne, Ruud, Heil, Tempstar and Coleman.
