Year-Round A/C Repair You Can Count On - The air conditioner is often the first thing you adjust when you start your vehicle — especially on a hot day. The cabin temperature can be up to 30 degrees hotter than outside, making a working A/C not just a comfort, but a necessity.

A/C Air Conditioning Performance Check

At Sergeant Clutch Certified Auto Repair Shop, our Certified A/C Mechanics will perform a comprehensive Air Conditioning System Evaluation to properly diagnose any cooling problems your car or truck may have.

A malfunctioning A/C system doesn’t always mean you need a full repair — sometimes a simple diagnostic or recharge can restore full performance. That’s why we offer a detailed A/C Performance Check to pinpoint the issue and get your system blowing cold again.

If you’re experiencing warm air from your vents, unusual noises, or inconsistent cooling, it’s time to get your A/C system checked by the experts at Sergeant Clutch. Schedule your A/C Diagnostic Service today at our San Antonio location!
