AC Blowing Warm Air in San Francisco, CA

AC blowing warm air in San Francisco, CA usually means the indoor blower is running while the outdoor unit is not doing its job. Walk outside and look. If the big fan on top of the condenser is still and the unit hums, the capacitor or the contactor is the likely fault. If the fan spins but the larger copper line going into the house is warm, the compressor may not be pumping.

Our crew tests before we swap anything. We read the capacitor in microfarads against the rating on its label, check the contactor points for pitting, and confirm 240 volts is reaching the unit. A tripped breaker or a blown fuse in the outdoor disconnect causes the same warm air symptom, and that fix costs a lot less than a compressor.

Thermostat settings matter too. A thermostat left on FAN ON pushes room temperature air through the vents between cycles, and on a hot afternoon it feels warm.

If your AC blowing warm air turns out to be a bad capacitor or a condenser fan motor, we carry both on the truck. Call (866) 703-1217.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about AC Blowing Warm Air in San Francisco, CA.

Talk to our crew
Is it worth repairing an older R-22 system?
Sometimes. R-22 has not been produced or imported in the US since 2020, so any recharge uses reclaimed refrigerant at a high price. A small electrical repair on an R-22 unit can still make sense. A major leak or a failed compressor on one usually does not. We'll give you both numbers.
Why is there ice on my AC lines?
Ice forms when the indoor coil gets too cold, usually from low airflow (dirty filter, dirty coil, weak blower) or low refrigerant charge. Turn cooling off and run the fan to thaw it, then call us. Running a frozen system can damage the compressor.
Can you just add refrigerant to my AC?
We can, but it rarely makes sense on its own. A central AC system is sealed, so low refrigerant means a leak. Topping it off without fixing the leak means the charge leaks out again. We find the leak, repair it and weigh in the correct charge.
How long does a central AC system usually last?
Many central air systems run 12 to 15 years with regular maintenance. Units near the coast, where salt air corrodes coils, and units in very long cooling seasons often wear out sooner. Age alone is not a reason to replace, but it factors into repair decisions.
Do you work on heat pumps and furnaces too?
Our focus is central air conditioning: split systems and packaged units, the outdoor condenser and the indoor coil and air handler. Call (866) 703-1217 and tell us what you have, and we'll let you know if it is a job for our crew.
