Best Garage in Royal Palm Beach for Your Audi’s Air Conditioning Compressor Repair

The air conditioning compressor of an Audi works by compressing the refrigerant gas that is driven by the engine belt. It increases the temperature and pressure before circulating it through the air conditioning system to take away the heat inside the vehicle. This process cools the air inside the vehicle.

The AC compressor acts as the heart of the system and maintains the consistent refrigerant flow through the entire cycle. A faulty compressor will not regulate the flow of refrigerant correctly. This can cause the air conditioning to not cool the air properly. At Milestone Motors, our mechanics specialize in service and repairs on Audi.

Common issues we see with Audi AC compressors are refrigerant leaks, low lubrication, dirty condensers, faulty compressor clutches, or physical damage to the actual compressor. All of those issues can cause signs such as warm air blowing from vents, unusual noises, reduced airflow, cycling issues, and increased engine load. This task requires an Audi expert to repair it. Let our mechanics, with years of experience, fix your air conditioning compressor.

Our technicians will diagnose and repair your Audi’s AC compressor by checking for leaks, high and low side pressures of the system, and potentially replacing the air conditioning compressor. We strongly suggest you regularly maintain your AC compressor so that it will not have to be replaced prematurely.

Audi AC System Cycle

The AC system cycle in your Audi involves its compressor turning on to flow refrigerant through the system. This cools the air by taking in the heat from the evaporator. That heat is then released outside of the vehicle through the condenser. The cooled air is allowed to be blown through the vents then and cycles until the desired temperature is met. The process is repeated as necessary to maintain the temperature.

• Low-pressure refrigerant
  • From the evaporator, a low-pressure refrigerant gas will enter the compressor.
• Compression
  • The AC compressor will compress the refrigerant and raise its temperature and pressure.
• Condenser
  • Once the hot, high-pressure refrigerant moves to the condenser, the condenser will release the heat to the air outside. This will transform the refrigerant into a high-pressure liquid.
• Expansion valve
  • The temperature and pressure of the liquid refrigerant will reduce once it passes through the expansion valve.
• Evaporator
  • The refrigerant, which is now cool and low-pressure, will enter the evaporator. Then it will absorb the heat of the air inside the vehicle. This will cool the air inside the cabin down.
• Return to compressor
  • The cycle will start again when the now low-pressure and warm refrigerant returns to the compressor.

Key Problems With an Audi’s Air Conditioning Compressor

At Milestone Motors, these are the most common problems we see with faulty air conditioning compressors.

• Refrigerant leaks
  • Caused by damaged seals or worn hoses, the refrigerant will leak under the vehicle in puddles and possibly leave a stain once it evaporates. This is one of the most common signs of compressor failure.
• Low lubrication
  • Low oil in the system will lead to premature failure of the compressor through wear and tear on the components of the AC compressor.
• Dirty condenser
  • A dirty condenser will hinder heat dissipation and cause the compressor to become overheated.
• Faulty compressor clutch
  • A faulty compressor clutch will not allow the compressor to turn on properly and lead to weak cooling.
• Physical damage
  • Impact directly on the compressor can cause damage to the compressor housing or internal components. A collision from an accident will do the same.

Signs That Your Air Conditioning Compressor Needs to Be Replaced

If you think your AC compressor needs to be replaced, look for these common signs and bring your Audi to our shop in Royal Palm Beach.

• Warm air blowing from vents
  • When warm air is blowing from the vents, this is the most apparent sign that the car’s AC compressor is failing.
• Unusual noises
  • There are odd noises when you turn the AC on. Sounds will range from grinding, rattling, and clicking.
• Reduced airflow
  • The cooling seems to be weaker than normal inside the cabin.
• Cycling issues
  • The Audi’s compressor is frequently turning on and off.
• Increased engine load
  • Extra strain will be put on the engine if your compressor is failing.
