AC Short Cycling in San Francisco, CA

AC short cycling in San Francisco, CA means the system turns on, runs a few minutes, shuts off and repeats. It wears out compressors, runs up the power bill and leaves the house sticky, because short run times never pull enough moisture out of the air.

Our crew looks at the causes in order. An oversized system cools the air near the thermostat too fast and shuts off before the rest of the house catches up. A thermostat mounted near a supply register or in direct afternoon sun reads the wrong temperature. A failing thermostat or a loose wire sends broken signals. On the mechanical side, a dirty condenser coil or a failing condenser fan motor lets head pressure spike until a pressure switch trips the unit off. Low refrigerant can trip the low pressure switch the same way, and a frozen coil can cause it too.

We time the cycles, read pressures while it runs, and check the thermostat location and wiring. When the thermostat is the fault, we replace it and set it up to match your equipment. Call (866) 703-1217.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about AC Short Cycling in San Francisco, CA.

Talk to our crew
How often should I get an AC tune up?
Once a year, in spring, before the first long stretch of hot weather. In long cooling season states, some homeowners book a second check in late summer. A yearly AC tune up catches weak capacitors, pitted contactors and clogged drain lines while they are still cheap fixes.
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.
Why is water leaking from my indoor unit?
Most of the time it is a clogged condensate drain line, a cracked or rusted drain pan, or a frozen coil that is melting. Turn the system off to limit water damage and call us. We clear the line, check the pan and test the safety float switch.
