Do you know that your car's air conditioning needs to be
serviced at least every 15 months? This means that the gas and
filter should be renewed. Lack of regular service can lead to
expensive air conditioning repairs.
You should run your air con for at least 10 minutes a week
all year round. The gas carries oil that keeps the sealing O
rings in good order. Failure to run the air conditioning
regularly can cause the O rings to dry out and let gas escape.
You can use the air con on any temperature.
Running a vehicle's air conditioning system on insufficient
gas can cause a multitude of problems leading to expensive
repairs.
Never get a car's air conditioning system topped up.
If you have a leaking system GET IT FIXED. Knowingly leaking
gas into the environment is illegal and very bad for the
environment.
Did you know that the old R12 gas (pre 1994 vehicles) is
approx 8000 times more damaging to the ozone than CO2? The
current gas R134a does not harm the ozone but adds greatly to
global warming.
Never try to release gas from a car's air conditioning
system. It's dangerous! It freeze burns on contact and disperses
oxygen and is heavier than air. It boils at approximately minus
30 degrees. Licensed technicians are trained how to handle it.
Do not fit used auto air conditioning parts such as condensers or
filters. Systems that have been used before and the internals
left in contact with air will form acid and corrode from the
inside making them weak.
A car's air con system must be moisture free, hence
the filter has a desiccant inside to absorb moisture. The amount
it can absorb is 20 ppm (parts per million) - equivalent to a
tear drop.
Retro fitting a pre 1994 car to the current gas is more
involved than just changing the charging ports.
