5 Most Common Problems with Car A/C Units
There’s perhaps no more disheartening feeling to discover that your car’s air conditioning isn’t working properly, especially on a hot day stuck in traffic. Overheating in the car can be frustrating, and can even lead to problems like road rage. Especially when you’re on the beltline in Madison, WI.
What’s going on with the a/c unit when it’s acting like this? Below are 5 of the most common things that go wrong with the air conditioning in your car.
1. Blocked or Broken Condenser
The condenser’s job is to use air intake from the front of the car as you’re driving along to re-cool refrigerant after compression. The condenser can get blocked by various buildup and debris, after which it won’t be able to do its job. Clearing it out should fix this problem.
Alternatively, the condenser might actually be broken. If the condenser is impacted particularly hard by a piece of debris, then it can cause a puncture. This kind of physical damage can only be fixed by replacing the condenser.
2. Refrigerant Leak
The refrigerant is the key ingredient that makes the air in your a/c unit cool. It is moved about the a/c system via various hoses, which sometimes corrode or otherwise rupture and cause leaks, especially in the areas where the hoses connect to other parts of the system. This can be fixed using a special sealant, or by replacing the hosing.
3. Electrical Problems
Even for the professionals, electrical problems are where a/c faults get somewhat complex. Of course, an experienced technician at Aeschbach Automotive knows what to look for and what to do about it, but it remains a challenge, especially in diagnosing the exact issue. The a/c unit is fairly complex, and it could be any one of a number of wires that are causing the problems. This is one issue you should always leave to the professionals.
4. Bad Compressor
The compressor is the part of the a/c system that keeps all of the various components moving, especially the refrigerant. It circulates refrigerant, keeping everything running smoothly and the air flowing nice and cold. The compressor can go bad through various technical faults, but also simply through lack of use. If you live somewhere with a very mild climate in which you hardly use your air conditioning system, you might find this happens more frequently.
5. Cooling Fan Faults
Similar to the condenser, the cooling fans can be damaged by the impacts of incoming debris. The fans’ main function is to cool the condenser, so when they are not working, the system ends up more likely only blowing hot air. The fans themselves might not be damaged, but rather one of their fuses is blown or some other electrical problem. You can visually inspect the fans to see what’s what, but we recommend letting a professional handle this one since it pertains once again to the electrics.
