MAHLE Aftermarket is highlighting the importance of reminding customers to have an A/C service. According to the company, the following article offers a convincing argument, particularly if the last service was two or more years ago.
Even if it is a closed system, the HVAC system loses around 10 to 15% of its refrigerant per year – particularly through the hoses and the many gaskets.
If there is too little refrigerant in the system, hardly any oil mist reaches the gaskets and hoses, and they become brittle – eventually casuing leakages.
If there is too little refrigerant in the system, the compressor also suffers. In this case, the compressor has to work at full load, but won’t be able to achieve the necessary pressure and therefore the desired temperature in the vehicle.
Overheating = expense
When the compressor is overworked, it becomes overheated. This leads to the refrigerant oil being damaged and coked, with its lubricity considerably reduced. That’s the end of the compressor: metallic abrasions and chips from the compressor contaminate the entire system. The HVAC system has to be completely flushed, and some components will need to be replaced, costing time and money.
Keep customers in the know
Your customers won’t be able to check for themselves whether their vehicle has too little refrigerant. Yet the A/C service is often not a prescribed part of regular maintenance, so, it’s a good idea to use a tyre change appointment to offer your customers an A/C service.
