Your car’s AC was blowing cold air yesterday. Today it’s pushing out warm, stale air like a hair dryer. Something in the system has failed, and until you know what it is, you can’t fix it. This guide walks you through the six most common reasons your car’s air conditioning stops cooling, what each one means, and how Mission Auto Repair in Winchester, VA diagnoses and resolves each one.
Brad Hindman, our ASE Certified Master Technician, sees this pattern every summer. “Refrigerant leaks and compressor issues account for most of what we see once the heat hits,” he says. “The blend door and fan failures come in too, but they’re often misdiagnosed first. That costs the customer more.” That’s exactly why accurate diagnosis matters before any repair work starts.

Noticing a puddle under your car after a summer drive can be alarming, but not every drip means trouble. The A/C system naturally drains condensation as part of normal operation. The real question is knowing the difference between harmless moisture and a refrigerant leak that needs immediate attention.

At Mission Auto Repair in Winchester, VA, we use professional-grade detection methods to find leaks fast. We fix them before they turn into a full system replacement.
