Keep the car’s AC system running optimally to ensure your commutes are comfortable year-round. However, a vehicle cooling system is complicated, and it can be challenging to know when it needs to be serviced by an auto repair mechanic. Here are a few warning signs to keep on your radar.

Which AC Issues Require Auto Repair?

1. Warm Air

Your car’s AC cools the air before the vents circulate it around the cabin. If you notice the AC is blowing warm air or isn’t responding when you change the temperature, the condenser may be broken. This component is supposed to collect heat from the vehicle’s interior and release it outside via gas or liquid refrigerant.

2. Electrical Issues

The AC should immediately respond when you adjust the temperature setting. You likely need professional auto repairs if the system works intermittently or doesn’t turn on. These problems indicate an electrical issue, and the car may need new sensors or signal wires to restore function.

3. High Humidity

The AC may be dirty if the car still feels humid when the windows are up and the cooling system is running. Debris and moisture can accumulate in the system and lower the air quality in the cabin, making it smell musty. Have an auto repair technician clean out the ventilation components to restore comfort.

4. Odd Sounds

You should hear a quiet whooshing noise when the AC kicks on. If the system exhibits any other sound, the vehicle needs attention. Rattling often indicates a failing compressor, while an issue with the compressor pulley can cause grinding.
