A/C Services by Minsky Mercedes and BMW

Home / A/C Services by Minsky Mercedes and BMW

At Minsky Mercedes and BMW, we specialize in providing comprehensive air conditioner (A/C) services to ensure your vehicle’s A/C system is functioning optimally. Our skilled technicians are well-versed in diagnosing and repairing common A/C issues, ensuring you stay cool and comfortable on the road. We provide A/C services for a wide range of luxury and premium brands, including Audi, BMW, Mini Cooper, Porsche, Land Rover, Volvo, Lexus, Mercedes-Benz, Volkswagen, and more. Below is an overview of the A/C system components, common issues, and the services we offer.

Common A/C System Components and Their Issues


Function: The compressor is the heart of the A/C system, responsible for compressing the refrigerant and circulating it through the system. It converts low-pressure gas into high-pressure gas, enabling the refrigerant to flow through the condenser.

Common Issues:

  • Leaks: Refrigerant leaks can occur due to worn seals or damaged hoses.
  • Clutch Failure: The compressor clutch may fail to engage, preventing the compressor from operating.
  • Bearing Wear: Bearings inside the compressor can wear out, causing noise and reducing efficiency.


Function: The condenser is located at the front of the vehicle and is responsible for dissipating heat from the refrigerant. As high-pressure gas passes through the condenser, it cools and converts into a high-pressure liquid.

Common Issues:

  • Clogging: Debris can clog the condenser, reducing airflow and cooling efficiency.
  • Leaks: Physical damage can cause leaks, resulting in refrigerant loss.
  • Corrosion: Over time, the condenser can corrode, leading to reduced performance.

Expansion Valve

Function: The expansion valve regulates the flow of refrigerant into the evaporator. It reduces the pressure of the high-pressure liquid refrigerant, allowing it to expand and cool before entering the evaporator.

Common Issues:

  • Blockages: Dirt or debris can block the valve, preventing proper refrigerant flow.
  • Malfunction: A faulty expansion valve can cause inconsistent cooling performance.

Evaporator Core

Function: Located inside the vehicle, the evaporator core absorbs heat from the cabin air. As low-pressure refrigerant flows through the evaporator, it evaporates and absorbs heat, cooling the air that is then blown into the cabin.

Common Issues:

  • Leaks: Corrosion or physical damage can cause leaks in the evaporator core.
  • Clogging: Debris and moisture can clog the evaporator, reducing cooling efficiency.
  • Mold and Mildew: Moisture accumulation can lead to mold and mildew growth, causing unpleasant odors.

Refrigerant Types: R-134a vs. R-1234yf


  • Common Use: Widely used in vehicles manufactured before 2014.
  • Environmental Impact: Higher global warming potential (GWP) compared to R-1234yf.
  • Cost: Generally less expensive than R-1234yf.


  • Common Use: Standard in vehicles manufactured from 2014 onwards.
  • Environmental Impact: Lower GWP, making it more environmentally friendly.
  • Cost: More expensive due to its lower environmental impact and newer technology.

A/C Service Diagnostics and Costs

A/C Service Diagnostic

Service Includes:

  • Recover: Removing the existing refrigerant from the A/C system.
  • Vacuum: Creating a vacuum in the system to remove moisture and check for leaks.
  • Recharge: Recharging the system with the appropriate refrigerant (R-134a or R-1234yf).
  • Check for Leaks: Using dye and electronic leak detectors to ensure there are no leaks in the system.

Cost: The approximate cost for an A/C service diagnostic, including recovery, vacuum, recharge, and leak check, varies:

  • Freon Service (R-134a): $160 on average.
  • Optiom (R-1234yf): $430 on average.
