Air conditioning is not just for staying cool in the summer, it also plays a major part in helping to quickly demist your vehicle in winter.
It is important to get your vehicle's air conditioning system checked out a least every 2 years to keep it at its most optimal efficiency as at least 10% of the refrigerant gas is lost each year.
Keeping the air conditioning system in good running order prevents any build up of bacteria that gives off an unpleasant odour and the system from becoming ineffective.
