Use That Air-Con!


When proper air-conditioning arrived in cars it was like a sort of heaven. No more having to open windows only to find that the air outside was as hot as the air inside; no more getting blown to bits by the wind and no more encounters with massive, dangerous insects, like wasps.

Air-conditioning is great, but there’s a problem. Because of the expense of fuel and the fact that we are told – and it’s true – that cars use more juice when the air-con’s on, we have taken to minimising the use of that chilly blaster, especially in the winter when we don’t use it at all.

This is a bad thing for air-conditioner units. The system uses a refrigerant fluid that is compressed and decompressed within a sealed system, changing it from a liquid to a gas and back again. This process absorbs heat from the air, thus cooling the cabin. Loss of fluid means the system won’t work.

If the air-con remains unused for long periods the pipes and seals can begin to dry out and start to leak. Because many people never read their car handbooks they miss the manufacturers advice to run the air-conditioning system at least once or twice a week  for between ten and fifteen minutes – regardless of the weather.

If the system stops working because it has lost fluid for the above reason – and this happens a lot to bemused drivers, especially of older cars – the car manufacturer will probably deem this to be a consumable and therefore not covered by any warranty. It will be your fault and there’s nothing you can do about it except reach for the credit card and have the system re-gassed.

On a new or nearly new car this fault shouldn’t happen. If something does go wrong then it’s probably a real fault and will be covered at the manufacturers effect.

Solution? Always run your air-con regularly, all year round. You don’t have to suffer an icy blast because you’ll have the heater on. If fact, running the air-con will help freshen the air inside a heated muggy car. Also, always ensure the system is checked – and re-gassed if necessary – at every service. That way the air-conditioner will always be tip-top and ready for work.
