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
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 to 3 years depending on usage.
Are there any stickers under the bonnet,giving you dates 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,
