Compressor Repair in San Francisco, CA

Compressor repair in San Francisco, CA starts with proving the compressor is really the problem. Plenty of units get written off with a dead compressor when the actual fault is a weak capacitor, a burned contactor or a loose wire at the terminal block. We test those first.

To check the compressor itself, our crew measures winding resistance across the common, start and run terminals, checks for a short to ground, and reads amp draw against the rated load amps on the data plate. A compressor that trips its internal overload and then restarts after it cools often has a charge or airflow problem pushing it too hard. A compressor that is locked rotor, drawing high amps and not turning, may respond to a hard start kit if the windings test good.

When the windings are open or shorted to ground, the compressor is done. At that point we give you honest numbers. A compressor swap on a 5 year old system still under parts warranty can make sense. On a 15 year old R-22 system it usually does not.

A correct refrigerant charge keeps compressors alive. Call (866) 703-1217 for a real diagnosis.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about Compressor Repair in San Francisco, CA.

Talk to our crew
Why is my central AC running but not cooling the house?
The usual causes are a clogged filter, a dirty outdoor condenser coil, low refrigerant from a leak, or a failed capacitor that has stopped the outdoor unit while the indoor blower keeps running. Our crew measures the temperature split across the indoor coil to narrow it down before we quote anything.
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.
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.
What should I do before the technician arrives?
Check that the thermostat is set to COOL and below room temperature, check the breaker and the outdoor disconnect, and look at the filter. If there is ice, turn cooling off and run the fan. If there is a burning smell, shut the breaker off and leave it off.
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.
