Only to a small extent. Up to approximately ten years ago only top of the range models had air-conditioning. The list included some Lorries, Tractors and Combine Harvesters. All over the world, all the above vehicles and including domestic appliances such as fridges, freezers, aerosol cans etc., all used R12 (a refrigerant) or 'CFCs'. These all belong to the same family. Up until the 80's it was maintained that R12 was safe to release into the atmosphere. This refrigerant R12 is only found in cars manufactured until approx '1993'. There are other types of refrigerant to replace R12 but these are slightly more expensive. Nearly all modern cars use R134a, a refrigerant which is Ozone friendly. R134a can affect global warming if released into the atmosphere, which is why a safe handling licence is required to use this refrigerant.
Why should I have my air-conditioning serviced if it's working ok?
air-conditioning system needs
servicing the same as your car
engine. It needs oil for the
compressor or it will seize up.
There is a filter that collects
debris and moisture from the
coolant, eventually the filter gets
blocked, this will lessen the
performance of the system and
consequently the unit will stop
working. You can guarantee it will
be at the hottest time of the year.
maintenance and Regular servicing
How do I know when its time for my air conditioning to be charged?
Questions to ask yourself
How old is my car?
Normally you would not need to recharge your system for approximately 4 years from new. After that, every 2 to3 years depending on usage.
Are there any stickers under the bonnet,giving you dats of when it was last recharged? If you cannot see anyit is better to have it checkedout. It will save you money in the long run especially if you have just purchased the vehicle, Better to be safe than sorry,
