Common problems we fix

AC systems commonly run into weak airflow, refrigerant leaks, or units that won’t cool or respond to the thermostat, often from a failing compressor or frozen coil.

We diagnose the real cause first, including on multi-zone systems.

Common signs and causes

  • If your air conditioner won’t start at all, the issue may be a tripped circuit breaker, a blown fuse, a faulty thermostat, or a failed capacitor.
  • An AC that turns on and off too often is commonly caused by a dirty air filter, low refrigerant, an oversized unit or a faulty thermostat.
  • We also fix units that aren't cooling, weak airflow, refrigerant leaks, thermostat issues and general performance problems.
  • Central air problems are usually felt before they are seen: warm air from the vents, a system that runs constantly, ice on the lines or an outdoor unit that will not start.
  • The fix depends on whether the fault is electrical, airflow related or in the refrigerant circuit.

AC repair questions

Why is my AC running but not cooling the house?

Low refrigerant from a leak, dirty coils and a failing compressor are the usual reasons. Restricted airflow, often from a clogged filter, can cause the same thing.

Do you repair multi-zone systems?

Yes. Zoned systems add dampers and extra thermostats, which we check along with the main equipment.

What should I check before calling?

Confirm the system is in cooling mode and that the outdoor unit's breaker has not tripped. A very dirty filter is also worth swapping, since it can choke the airflow.
