Chicago area winters can be brutal – no doubt about it. When the lazy days of summer finally arrive, we’re ready to turn off the heater and drive with the windows down. But, as we all know, our car air conditioner is eventually needed for those steamy summer days with high temperatures and high humidity.
We turn on the A/C and wait for the big cool down. What if your auto’s A/C is blowing hot air, even after a few minutes of waiting? Does it mean you’re headed for a melt down? Don’t lose your cool yet! There can be one or more reasons your auto air conditioning is blowing hot air. Many people assume their A/C system just needs a recharge, and then everything should be good to go. Not so fast. There are several other issues that could be in play.
COMMON CAR A/C REPAIR ISSUES
Leaking Refrigerant – When a car’s air conditioner gradually loses its cool, one of the most common reasons is a leak in the system. In some cases, an additive combined with the freon will take care of the problem. If your car is over five years old, brittle or inelastic rubber O-rings used throughout your auto’s A/C system are more likely to blame.
Electrical Issues – Your car’s AC system is a tangle of wires, fuses, switches and relays. A fault with any of these items can cause your auto’s A/C to stop functioning and blow hot air.
Failing Expansion Valve – Is your auto’s A/C alternating between blowing cold then hot air? It could be your expansion valve is corroded or failing. This leads to ineffective refrigerant flow-either too restrictive or not restrictive enough. The result is a constant swing from hot to cold air.
Faulty Cooling Fans – When fans aren’t operating at full strength, your car’s AC will gradually begin blowing hot air. The fans can be damaged by road debris. The issue may also be related to blown fuses or electrical issues.
Blocked or Broken Condenser – An A/C system’s condenser re-cools hot refrigerant once it’s been compressed. The condenser can easily break or become blocked from road debris. That means air isn’t cooled as effectively or not at all.
Compression Issues – The compressor is the main machine of your auto’s air conditioning system. If the compressor malfunctions, coolant can’t circulate through the system. That means no cool air. Lack of use over a long period of time is the most common reason compressors fail.
AUTO A/C SERVICE OR REPAIR
When your car’s air conditioning is not functioning properly, all is not lost. Give Clark’s Car Care a call at 630.345.4178. You can also schedule a service appointment online. When you come in, it’s helpful to know how your auto’s AC has been performing. How long has your air conditioning been blowing hot air? Was it a sudden or gradual loss? Is the car making any noises after turning on the A/C? Are there any other symptoms you’ve noticed? This provides us additional information to help pinpoint the issue.
While a full freon charge may fix the problem, we can also perform a comprehensive inspection to ensure no other issues are present. This inspection includes a cooling system performance test, inspection of hoses, and a test for leaks. We also provide FREE tips for preventive maintenance to help extend the life of your air conditioner and prevent costly repairs in the future. That means more money in your pocket in the future!
