Green light for an optimal climate

When the temperature in the cabin is optimal, this is due to a sophisticated piece of technology. The core component of vehicle air conditioning is the air conditioning compressor, which is usually driven by the vehicle engine via a V-ribbed belt. It compresses the gaseous refrigerant and forwards it to the condenser, where the compressed gas loses pressure and cools down.

With our new air conditioning compressors product group, we’re now offering access to top quality.

How to make air conditioning compressors last longer

An air conditioning compressor usually lasts a car’s entire lifetime. Insufficient or incorrect maintenance of the air conditioning circuit, however, can lead to compressor damage. Penetrating moisture or a lack of oil can then result in defects.

Disturbing noises develop and the cooling capacity is reduced. The HVAC system can even break down completely, requiring the air conditioning compressor to be replaced!

Signs that the air conditioning compressor has been damaged or has failed include:

  • Coolant leaking from the compressor
  • Insufficient cooling, or absence of cooling
  • Noise
  • Error messages in the air conditioning control unit or central control unit

Possible causes of compressor failure:

  • Incorrect installation
  • Insufficient compressor oil or refrigerant
  • Leaks in the air conditioning system
  • Damage to individual air conditioning components
  • Solid matter contamination (metal swarf, etc.)
  • Moisture in the air conditioning circuit (due to corrosion, etc.)

MAHLE goes all out for air conditioning

In the long run, even a first-class air conditioning compressor can only perform at its best when it’s part of a good team. Of course, MAHLE has these products in its range, too!
