There’s nothing worse on a hot summer day than realizing your car’s air conditioning is on the fritz. This is especially true if you live in an area where the temperatures reach upwards of 100 degrees Fahrenheit during the summer.

There are many things that can cause a car’s AC unit to stop blowing cold air. It’s important to learn about these reasons and to take your car to a reputable local auto repair shop for repair when necessary. Read on if you’re wondering, “Why is my car’s air conditioner not blowing cold air?”

  • Problems with the condenser: Your AC unit’s condenser is responsible for keeping the refrigerant cool. So, if your air conditioner is blowing out hot air, the problem could be with the condenser. Condensers can sometimes break after a front-end accident. They can also become clogged with debris over time, causing them to malfunction.
  • Fluid leaks: Leaking refrigerant is a common cause of air conditioner problems. This chemical is responsible for cooling the warm air that enters your vehicle’s air conditioning system. Your vehicle requires the right amount of refrigerant for the car AC to operate correctly, so a leak could cause things to heat up really fast. There are many things that could cause a refrigerant leak, including an old hose, punctured evaporator and more. It’s often hard to tell if you have a refrigerant leak, as the liquid evaporates very quickly.
  • Electrical system issue: Most car air conditioning systems feature electrical parts, and an electrical problem with your vehicle could easily affect the air conditioning. These problems are often caused by something like a blown fuse or faulty wiring. Like fluid leaks, diagnosing electrical issues is difficult if you’re not experienced. That’s why it’s always best to ask for a professional’s opinion before trying to replace fuses or wiring on your own.
  • Compressor issues: The compressor is an essential part of your vehicle’s air conditioning system that allows the refrigerant to flow efficiently. A compressor can become blocked by leaves, small sticks and other debris. It’s sometimes easy to spot and remove this debris on your own. However, debris could also puncture your compressor by going through your vehicle’s grill. In this situation, you’d likely need a technician to repair your compressor.
  • Low refrigerant levels: If the refrigerant levels are low in your vehicle, the air conditioning system could need a recharge. Most vehicles will lose some degree of refrigerant over time. Sometimes, this missing refrigerant will cause the air from your air conditioner to feel a bit warmer than usual. If this is the cause with your vehicle, go to an auto shop and ask about an air conditioner recharge. They can easily diagnose and correct the issue.

While proper maintenance can help prevent air conditioner issues, accidents can always happen. It’s important to bring your vehicle to an auto repair shop at the first sign of an issue. Putting off repairs could result in the problem getting much worse.
