Not Cooling
The unit runs but the air isn't cold. We check refrigerant charge, superheat and subcooling, the compressor, and airflow before quoting anything.

AC & HEAT PUMP REPAIR — AUBURN, WA
AC Repair in Auburn
When a heat wave settles over the valley, an AC that won't cool is miserable. We diagnose air conditioners, heat pumps and mini splits, quote the repair upfront, and get your house comfortable again.
Auburn AC Repairs
Refrigerant Leaks
Low charge is a symptom, not the problem. We find and repair the leak instead of just topping it off and sending you a bill every summer.
Frozen Coils
Ice on the indoor coil or line set usually means restricted airflow or low charge. We fix the cause, not just the ice.
Heat Pump Repair
More Auburn homes cool with heat pumps every year. We service reversing valves, defrost boards, inverters and outdoor fan motors.
Mini Split Service
Ductless systems need clean blower wheels and filters to cool properly. We service Mitsubishi, Midea, Daikin and other ductless brands.
Electrical & Controls
Failed capacitors, contactors, thermostats and low-voltage faults — the most common no-cool calls and usually the fastest fixes.
Cooling in the Green River Valley
Auburn's valley location traps summer heat the same way it traps winter cold. When the rest of the Puget Sound region is warm, the valley floor is often a few degrees hotter — and heat waves that used to last two days now stretch for a week. Systems that used to be optional are now essential.
Because cooling systems here sit idle most of the year, problems hide until the first genuinely hot stretch — then everything breaks at once. Capacitors that weakened over winter, condenser coils packed with cottonwood and grass seed, and slow refrigerant leaks all show up in the same few weeks.
Many Auburn homes also have cooling that was added onto heating-only ductwork years after the house was built. That mismatch is behind a lot of the 'the AC runs but the upstairs is still roasting' calls we get — the fix is often airflow, not refrigerant.
We diagnose the whole system — charge, airflow, electrical and controls — so the repair holds up through the rest of the season instead of failing again in three weeks.
