If your vehicle's air conditioning system is not performing correctly, there may be several reasons why. The AC in your automobile is comprised of several components, each of which play a significant role in cooling. For instance, parts such as the air compressor or expansion valve may be faulty and require replacement, or perhaps the AC has spring a leak. Here is a look at some of the more common issues that could could your car's air conditioner to fail:
1. The Air Compressor Is Faulty
Your car's AC air conditioner has an important job to do. This moving part is responsible for pumping the refrigerant through the entire system. If the AC is not cooling properly or fails to cool at all, a technician will check the clutch, examine the air compressor for leakage and listen for noises while the AC is in operation. He or she will also check for debris or oil that could be clogging the part. In the case of an older car with a lot of mileage, the air compressor may need to be replaced. Once thr air compressor has been replaced, refrigerant and oil will be added.
2. The Expansion Valve Has Become Clogged
One of the major signs of an expansion valve clog or breakdown is frost coming from the auto's vents. Another sign to look for is an air compressor that is constantly running. The expansion valve is located at the evaporator inlet, and its job is to regulate refrigerant in your car's air conditioning system. If the expansion valve is faulty or defective, it may affect the AC system. Preventing it from cooling properly. The system may not produce cold air, or blow warm air through the vents. If cleaning does not solve the clog, the expansion valve may need to be replaced.
3. A Leaking Condenser
If the air conditioning condenser has sprung a leak, any heat that passes through the refrigerant may not dissipate as it should. This may be causing poor performance of the AC system. If there is no leak from the condenser, the component may be blocked with debris. In any case, it is probably best to have the condenser replaced over time, especially in older cars.
4. A Worn or Blocked Air Conditioner Hose
Your vehicle's air conditioner hose may become worn down over time or clogged. A clog or worn out hose will restrict the flow of refrigerant, causing the system to fail or not cool properly. In such a case, a replacement hose is the solution.
While any of the above mentioned scenarios may cause an issue with your automobile's AC system, it's best to have a mechanic or technician perform an inspection and evaluation. Professionals like Jason's Auto Repair have the equipment and know-how to correct the problem in an efficient manner.Share
