A/C Service & Repair

Common A/C Problems

• Refrigerant Leak - Refrigerant is a truly remarkable compound that is responsible for your A/C working. It moves through the A/C hoses as a low-pressure gas, absorbing excess heat from the engine. Once it's heated, it becomes a high-pressure liquid; this liquid sheds the excess heat, becoming cold. If your system doesn't have enough refrigerant, you may find that warm air blows out of the vents instead of cool. Come to Shrewsbury Volkswagen, and our technicians will inspect the A/C system for leaks and then refill it with new refrigerant.
• A/C Compressor Trouble - The compressor is the part of the A/C system that compresses the cold liquid refrigerant into a gas so it can flow through the hoses. Compressors may become damaged, or they may simply lose their ability to function as time goes by. Whatever the cause, the best solution is to replace the old compressor with a new VW OEM compressor at Shrewsbury Volkswagen.
• Clogged or Damaged A/C Condenser - The condenser is where the liquid refrigerant sheds its heat and turns back into a gas. Over time, this condenser can become clogged and will need to be unblocked. However, the condenser can also wear out or suffer damage like the compressor and will need to be replaced.
• Damaged Cooling Fans - The cooling fans blow the cool air from the A/C system into your vehicle's cabin. If one fan has failed, it likely has physical damage. But if all of the fans stop working, it's likely an electrical issue.
• Clogged Cabin Air Filter - The cabin air filter keeps contaminants from entering your vehicle's cabin, and it will become clogged as time goes by. To keep the cool air flowing, you should have the cabin air filter replaced regularly.
