A car AC that blows warm air or won't cool below 60F needs diagnosis, not just a recharge. For Alderwood Manor drivers near the Alderwood Mall corridor and I-405, Tom's B&M Auto diagnoses AC systems properly — pressure readings, leak detection, and component testing — before recommending any repair. We stock R-134a and R-1234yf refrigerant and handle everything from a simple recharge to compressor replacement.
We measure vent outlet temperature, take high and low side pressure readings, and inspect the compressor clutch engagement, condenser, and hoses. Electronic leak detection used to find slow leaks UV dye misses.
We identify the root cause before recharging. A system that's low on refrigerant has a leak — recharging without finding and fixing the leak wastes your money. We quote the repair, not just the recharge.
Post-repair vent temperature and pressure check before return. AC service typically completed same day. System performance verified at operating temperature.
We don't just recharge leaking systems. A refrigerant recharge on a leaking system lasts 1-2 seasons before the same symptom returns. We find the leak source — O-ring fittings, service ports, hose connections, or compressor shaft seal — and repair it before recharging.
We service both R-134a systems (pre-2017 most vehicles) and R-1234yf systems (2017 and newer most vehicles). R-1234yf requires different equipment and refrigerant — shops without the right equipment can't legally service these systems. We have both.
We locate and repair the leak source before adding refrigerant.
Correct refrigerant for your vehicle year. Proper equipment for both systems.
Most AC repairs completed same day. Free vent temp test with every AC repair.
AC repair includes vent temperature measurement, high/low side pressure readings, electronic leak detection, compressor clutch inspection, and condenser visual inspection. We repair the leak source before recharging. Refrigerant type matched to your vehicle.
