Air Conditioning - Climate Control

Midas has developed a multi-point diagnostic test for A/C systems. If your A/C system is not cooling properly, there could be a number of reasons for this. Select stores are equipped to check for leaks and repair A/C systems from all major manufacturers.

How it Works

Your automobile's air conditioning (A/C) system is divided into two sides, known as the high side and the low side. The compressor, beginning at the high side, functions like a pump, moving refrigerant through the system. The expansion valve, which begins at the low side, restricts refrigerant flow, lowering the pressure and the temperature of the refrigerant.

What to Watch for

Your air conditioning system has parts that require lubrication to avoid cracking, which can lead to system leaks. Running your air conditioner regularly - even during winter months - helps lubricate these components and is recommended for many vehicles. However, some new models eliminate the need for this. Midas recommends that you consult your owner's manual or visit our expert mechanics to get the right information for your vehicle.
