Is the air-conditioning in cars responsible for the hole in the Ozone?

 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. All vehicles with air conditioning manufactured since 1st January 2017 include the new R1234YF air con gas which is more environmentally friendly. Bolams have the latest equipment to recharge systems using this type of gas.

 Why should I have my air-conditioning serviced if it's working ok?

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. Preventative maintenance and Regular servicing will:
