The A/C has to work harder to compensate for any lack of refrigerant, this can lead to premature failures in compressors, relays and fans. Our A/C service will test your system pressures, cooling efficiency, fan operation, belt and hose conditions and mode functions. We will fill your system to capacity and add a fluorescent dye for future leak detection. We do complete A/C repairs with a full 12 month 12,000 mile warranty.
