Called at 9pm when our AC quit in a heat wave. A tech from Air Conditioning Filters Guys was here in under two hours, found a bad capacitor, and we had cold air before midnight. Fair price, no drama.

Whole-home AC installation. Straight answers on sizing, a real load calculation, permits pulled, and the new system is quieter and cheaper to run. Recommended for any San Francisco homeowner.

They fixed the airflow problem three other techs missed - crushed duct in the crawlspace. Upstairs is finally comfortable.

San Francisco HVAC Questions & Answers
Do you offer same day AC repair in San Francisco?
Yes. Same day AC repair in San Francisco 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 Francisco?
Typical arrival for San Francisco and nearby communities such as San Gabriel, San Fernando, San Geronimo, San Dimas, San Gregorio, San Diego 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 Francisco cost?

My AC is not blowing cold air in San Francisco. 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 Francisco. 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 Francisco year-round. If you smell gas, leave the house first, call your gas utility, then call us.
Do you repair heat pumps in San Francisco?
Yes. Heat pump repair in San Francisco 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 Francisco?
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 Francisco?
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 Francisco.
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 Francisco?
