If your air conditioning is running but there's no cool air flowing, then you may have a defective expansion valve. The ‘brain’ of automotive air conditioning systems, expansion valves lower the pressure from the refrigerant liquid, allowing it to expand and become refrigerant vapour in the evaporator. Your car's blower circulates air across the cold evaporator and into the cabin with the refrigerant recycled through the air conditioning system. Expansion valves are incredibly important, and a host of expensive problems can occur if they fail or malfunction. Too much of refrigerant entering the evaporator can cause the evaporator to freeze, block up, and potentially burn out the air conditioning fan motor. This can also lead to the AC refrigerant remaining liquid, potentially entering and damaging the compressor. If you’re looking to safeguard your air conditioning and your wallet, take a look at the range above and enjoy fast, free delivery or click and collect from over 200 ECP locations nationwide.
