Air conditioning repair

Not cooling, short-cycling, leaking or making noise. We find the fault, quote it in writing and fix it.

Most AC failures come down to a handful of parts: a weak capacitor, a dirty coil, a clogged drain, a low refrigerant charge or a failing fan motor. The work is finding which one it is before anything gets replaced.

A technician tests the system, shows you what failed and gives you the price in writing. You decide from there. If the unit is not worth repairing, we say so and show you why.

The two summer failures we see most are a run capacitor that has drifted below its rating and an outdoor coil matted with dust and debris. Both are cheap to catch on a maintenance visit and expensive to discover on the hottest afternoon of the year, when every shop is busy.

What to expect

How an AC repair visit goes

An owner answers the phone, 6am to 10pm, seven days, and we usually get to you within a few hours. Tell us what the system is doing and where it is. If it is not safe to run, we say so before anyone drives out.

On arrival the technician puts instruments on the system, not just eyes: refrigerant pressures, the capacitor and contactor, airflow, the temperature split across the coil, both coils and the drain. That takes a while, and it is the part a driveway diagnosis skips. When the fault is found, you see what failed and why.

Before any work starts you see a written price. Go ahead and the $69 diagnostic is credited toward it. Our labor carries a one-year warranty on top of the manufacturer's. Many repairs are finished on the same visit. If a part has to be ordered, you hear how long it will take before you decide.

Good to know

Before you call

  • Turn it off if it is icing or leaking

    A frozen indoor coil keeps making water as it thaws, and a compressor pushing against ice is working against itself. Switch the system off at the thermostat and let it thaw before the visit. The tech needs it thawed to test it anyway. Read more

  • One breaker reset, then stop

    A single trip on a very hot afternoon can be a fluke. Repeated trips mean the compressor is drawing too much current, usually from a dirty coil or a weak start component, and the breaker is protecting it. Leave it off after the second trip. Read more

  • Warm air has three usual causes

    A tripped breaker or a thermostat set to fan, a dirty filter starving the airflow, or an outdoor unit that has stopped. Check the first two yourself. If the outdoor fan is not spinning while the indoor blower runs, that is the call. Read more

  • Age changes the math

    Central air conditioners typically last roughly 12 to 17 years, and long cooling seasons in hot attics push toward the lower end. Past that range, a repair buys fewer summers, and we say so before you spend on it. Read more

  • A backordered part does not have to mean a wait

    Condenser fan motors and control boards are the two parts suppliers run out of first. We keep tested, Boost Certified ones on our own shelves. Read more
