Car AC blowing hot air

Quick answer

A car A/C that blows hot air is usually low on refrigerant because of a leak, or has a failed compressor, condenser fan or blend door. A recharge without finding the leak only buys a few weeks.

Common causes

Refrigerant leakThe most common cause. O-rings, hoses and condensers leak with age.

Compressor or clutch failureNo cold air at all, sometimes with a noise when the A/C is switched on.

Condenser fan not runningCold on the highway, warm in traffic.

Blend door actuatorCold on one side, hot on the other, or a clicking behind the dash.

When to get it checked

Book soon. Running a leaking system can damage the compressor and make the repair bigger.

The repairCar A/C Repair →In South Florida a car A/C that blows warm isn't a comfort problem, it's an emergency. A recharge alone rarely fixes it, because refrigerant only goes missing through a leak. We find the leak or the failed part first, then quote the auto A/C repair in writing.
