Warm air and weak airflow
An AC that runs but does not cool usually has a refrigerant, coil or airflow problem behind it. We measure temperatures and pressures, find the actual fault and fix that, not the symptom.

What our ac repair covers
AC will not turn on
A silent system is often a failed capacitor, contactor, breaker or thermostat call that never arrives. We test the electrical path step by step and show you the failed part before replacing it.
Frozen coils and ice on the lines
Ice on the refrigerant lines means airflow or charge is off, and running the system frozen can kill the compressor. We thaw it safely, find why it froze and correct the cause.

Get an Honest QuoteQuestions callers ask about ac repair
How fast can you come out?
Call as early in the day as you can. No-heat and no-cooling emergencies are placed first, and we give you a straight arrival window on the call, not a vague promise.
Do you charge for the visit?
Estimates on new systems are free. For repairs, any diagnostic charge is explained on the call before anyone is dispatched, and the repair itself is priced in writing before it starts, so there are no surprises.
What should I do before you arrive?
Check the thermostat is set right and the filter is not clogged solid, both save real visits. If you smell burning, hear loud electrical buzzing or your CO alarm sounds, switch the system off and call us from a safe spot.
My AC is blowing warm air. Is it always the refrigerant?
No. Low refrigerant is one cause, but dirty coils, a failing blower, a bad capacitor or a refrigerant leak behind the low charge are just as common. Adding refrigerant without finding the leak only buys a few weeks, so we test first and show you the readings.
