Auto A/C & Heating Repair in Fullerton

Warm air on a hot Fullerton afternoon? We diagnose leaks, compressors and controls.

Quick answer

If your car's A/C blows warm, cycles on and off or makes noise, the cause is usually low refrigerant from a leak, a failing compressor or clutch, or an electrical or blend-door problem. Cedillo's in Fullerton diagnoses the cause before recharging so the fix lasts.

Recharging a leaking system just buys a few weeks. We find the leak or failed part first, repair it, then charge the system to spec.

We also repair heater cores, blower motors and climate controls.
