Top-rated independent heating and cooling across California's Central Valley and the Sierra foothills
AC Compressor Repair
We repair and replace failed AC compressors in homes across California and Nevada, on both split systems and attic or rooftop package units. You likely need this work if your outdoor unit hums but never starts, the breaker trips when cooling kicks on, or air from the vents is only slightly cool on a hot afternoon. Turn the system off at the thermostat so it stops trying to restart, then call us. We will come out, test the unit under load, and tell you plainly what failed.

What AC compressor repair actually involves
The compressor is the pump that moves refrigerant through the system, and it lives inside the sealed outdoor unit or the package unit on your roof. Most of the time the compressor itself is fine and the parts feeding it are not, so we start there. We test the run capacitor, contactor, wiring and incoming voltage, then check pressures and amp draw while the system runs. If the motor windings are shorted or the unit is locked up mechanically, we talk about replacement rather than parts.
What we check and what we replace
We check capacitor readings against the rating, look at contactor points for pitting, and measure how much current the compressor pulls on startup. A hard start kit sometimes brings back a tired unit that struggles to get moving in high heat. We also clear the condenser coil, because ag dust and cottonwood pack those fins tight and force the compressor to work against pressure it was never built for. Refrigerant charge gets verified, since a low or overcharged system kills compressors slowly.
How we decide repair or replacement
A compressor that tests open, shorted to ground, or seized is not repairable in place, so the choice becomes a new compressor or a new condensing unit. We weigh the age of the system, the condition of the coil, and whether the refrigerant it uses is still practical to source. If the rest of the equipment is sound, swapping the compressor makes sense. If the coil is corroded and the unit is well into its second decade, we say so and price out both paths.

Can a compressor be repaired, or does it always need replacing?
Often the failure is a capacitor, contactor or wiring problem feeding the compressor, and those are straightforward repairs. A compressor with failed windings or mechanical seizure has to be replaced, and we confirm that with electrical testing before recommending it.
Why does my breaker trip when the AC starts?
A compressor drawing too much current on startup will trip the breaker, usually from a weak capacitor, a dirty condenser coil, or failing windings. Leave the breaker off and call us. Repeated resets can damage the unit further.
How long does compressor replacement take?
Most compressor changeouts are a full day of work, including recovering refrigerant, brazing in the new unit, pulling a vacuum and recharging. Part availability can add time on older systems or less common refrigerants.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form. We ask what changed, when it started, and what the thermostat reads. That tells us whether to bring parts for a cooling fault or a heating fault.
- Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, airflow through the filter and coil, refrigerant pressures, and the outdoor unit. You get told what failed and why, in plain words, before anything is replaced.
- Step 3
Repair and verify
We make the repair, then run the system and measure the results at the vents. If a part needs ordering, we say so and give you a realistic window instead of a vague promise.

Why homeowners call us
- Built for real valley heatWe work in areas where afternoons sit above 110 degrees and systems run for months without a break. That shapes how we size repairs, check capacitors and contactors, and judge whether a compressor is genuinely done.
- Attic and package unitsPlenty of homes across the region run attic air handlers or rooftop package units instead of a garage furnace and a side-yard condenser. We are used to the access, the duct runs, and the drain issues those setups bring.
- Dust and debris we expectAg dust, cottonwood fluff and grass clippings pack condenser coils and starve a system of airflow. We clean what we find and show you the difference, rather than adding refrigerant to a unit that just could not breathe.
- Heating too, not only ACFurnace repair, heat pump faults and no-heat calls get the same attention as summer work. Ignition problems, cracked or failing components and short cycling all get diagnosed before we recommend anything larger.
