Without a working air conditioner, a car can feel like a hot oven on a sweltering summer day. If your AC isn’t working, you’ll need an auto mechanic’s help to fix it; however, knowing the cause of the issue can help the repair team resolve the issue quickly. Below are a few common signs that a car needs AC repair.

4 Signs Your Car’s AC Needs Repair 

1. Foul Odor

If you haven’t used the AC in a while, it may emanate an odd odor when you turn it on for the first time. Because of the lack of air circulation, moisture may have built up in the engine, which creates a breeding ground for bacteria and mold. If you notice a damp, musty smell when turning on the AC for the first time in spring, take your vehicle to an auto mechanic. Inhaling bacteria and mold spores can trigger allergy symptoms or other respiratory issues. 

2. Lack of Cooling

Note whether or not there is airflow, and pay attention if it is warm. Warm air likely indicates a compressor or refrigerant problem, as these components are responsible for cooling air. 

3. Strange Noises

With vehicles, strange noises are typically one of the first warning signs of trouble. Some sounds you may hear with a malfunctioning AC are rattling, clanking, and grinding. These may indicate a loose component or misaligned fan. There may also be debris caught in the system. 

4. Low Pressure

The air conditioner uses refrigerant stored in its coils to cool hot air. When there is a leak in the system, the liquid escapes, creating low pressure. Some refrigerant may escape gradually over time, or it may go bad. When the refrigerant is low or ineffective, you’ll notice less fresh air. Have an auto mechanic test the pressure and refrigerant levels. Keep in mind that refrigerant is highly toxic, and a leak should be fixed immediately to prevent hazards.
