AC Is Only Cold When You’re Driving Fast

You may find that your AC blows cool air and only blows cold air when you’re driving on the highway. This odd situation is caused by a problem with your compressor. The compressor is responsible for converting liquid refrigerant back into gas. It also controls the operation of the AC system. If you listen closely, you’ll hear a click now and again as the compressor switches on and off.

Compressors wear out like all other components. If your compressor is old or damaged, it’s probably not running as efficiently as it once did. A worn compressor slows down, which leads to only cool air in your cabin. The compressor speeds up when your drive fast due to the increased airflow into the AC system. We’ll examine your compressor and replace it if it’s wearing out.

Noisy AC

An AC doesn’t make any noise when it works apart from the clicking sound of the compressor clutch. Rustling, clunking, and other odd noises are always a sign of trouble. The problem could be a minor one, for example rustling noises are usually caused by leaves and other debris that blow into the AC system and move around with the airflow.

Clunking and harsher noise usually mean worn or damaged parts. A clunking noise, for example, could mean that one of your compressor’s bearings has failed. A broken or damaged bearing places additional strain on the working bearing. This can cause the healthy bearing to also fail. Our technicians will need to track down the problem in your AC then we’ll fix it.

Bad AC Smell

Musty smells from the AC are a sign that your AC has very unwelcome visitors. Bacteria and mold can easily find a home in the AC ducts due to moisture, darkness, and lack of air movement during the winter. These two organisms will rapidly spread throughout your AC system. They can also block valves, pipes, and other essential AC components.

To get rid of this problem, we pump a strong cleaning solution into the AC system. We also remove and replace the AC air filter. This filter can easily become a breeding ground for bacteria or mold. Once the cleaning solution has done its work, your car’s AC will be as fresh as a daisy.
