A dependable air conditioner will make driving a much cooler and more comfortable experience, whether you're going around the block or embarking on a summer road trip. If your AC isn’t working properly, the interior climate of the vehicle can become uncomfortably hot. Fortunately, by looking out for the following signs of problems with the system, you can bring the car to an auto shop to resolve the issue before the AC breaks down.

How to Tell if Your Car AC Needs Repair

1. No Air

A total absence of air from the vents can indicate a few possible issues. The AC controls may be broken, which could be due to a blown fuse in the electrical components, a bad relay, or a damaged fan. A clog in the vents could be preventing the free flow of air.

2. Hot Air

Hot air clearly means that the air conditioner isn't cooling like it should. A common cause of this issue is a lack of refrigerant, which absorbs heat from the air before cooling the air and sending it back into the vehicle. There may not be enough refrigerant in the system, or there could be a leak somewhere in the line.

Hot air can also be a symptom of a broken compressor or condenser, or an electrical problem like a broken fuse or frayed wire. In any case, take your car to an auto shop for a definitive diagnosis.

3. Strange Noises

Other than the comforting swoosh of air and the occasional hiss of the system pressurizing, no other sounds should be audible from the AC. If the pulley inside the compressor wears out, the air conditioner will grind or squeal when turned on.

If the compressor's clutch wears out, the AC will rattle. If mounting bolts have loosened, the AC will click or knock.
