Signs you need AC repair

- Ice on the indoor coil or on the refrigerant lines outside.
- The outdoor unit hums, but the fan does not spin.
- Water leaking around the indoor unit or furnace.
- The system turns on and off every few minutes.
- The breaker trips when the AC starts.
What to expect from an AC repair visit
We test the thermostat, filter, airflow, coil, refrigerant charge, capacitor and electrical parts to find the real cause. You get a clear explanation and the price before any work starts.
We repair central AC, heat pumps and ductless mini splits. If your system is older and repairs no longer make sense, we show you replacement options, including heat pumps that also heat in winter, with financing available on new systems. For a full check before summer, book our $49 HVAC diagnostic and maintenance visit.

AC repair questions
Why is my AC running but not cooling?
The most common causes are a dirty filter, a frozen coil, low refrigerant or a failed capacitor. Replace the filter and check the thermostat first. If it still does not cool, call for a diagnosis.
Why is my AC freezing up?
Ice usually means low airflow or low refrigerant. A dirty filter, a blocked return or a weak blower can starve the coil of air, and low refrigerant usually means a leak that needs to be found and fixed. Turn the AC off and let the ice melt before it runs again.
Is it worth repairing an older AC?
If the system is in good shape and the repair is small, yes. If it is 15 years or older or needs a major part like a compressor, replacing it with a heat pump is often the better value.
What should I check before calling for AC repair?
Make sure the thermostat is set to Cool and below room temperature, replace a dirty filter, and check that the breaker for the outdoor unit is on. If the AC still will not cool, call 425-201-1998.
