Symptoms of A/C System Failure

Is Your Air Conditioner Failing?

In San Antonio, a weak A/C is often caused by a refrigerant leak or a clogged expansion valve. If your vents are blowing warm air or you hear a rattling noise when the air engages, you likely have a worn compressor clutch. We provide professional A/C diagnostic estimates to pinpoint the leak before it leads to total system failure.

Cooling & Quality Warning Signs

  • Fluctuating Temps: Intermittent cooling or warm air at idle.
  • Musty Smells: Signaling evaporator core contamination.
  • Low Airflow: Indicating a blocked cabin air filter or blower motor failure.

Mechanical Red Flags

  • Noises: Grinding or squealing from the A/C compressor.
  • Fluid Leaks: Pooling refrigerant or UV dye traces.
  • Idle Issues: System fails to cool unless the vehicle is moving.

Yes. We specialize in heavy-duty A/C repair for commercial fleets. We service the high-capacity systems found in tractors and vocational trucks, ensuring your drivers stay cool and compliant during the long-haul South Texas heat.
How does UV dye help find A/C leaks?
