Frequently asked questions about car AC repair

Why is my car's air conditioning not blowing cold air?

There are several potential reasons why your car's air conditioning is not blowing cold air. Here are some common causes to consider, if you’re wondering why you need car AC repair:


  • Low Refrigerant Levels: Insufficient refrigerant, often due to a leak, is a frequent cause of AC problems. When refrigerant levels are low, the AC system cannot produce cold air effectively.

  • Faulty Compressor: The AC compressor is responsible for compressing and circulating refrigerant. If the compressor is malfunctioning or not engaging properly, it can result in warm or no cold air.
