Nowadays any new car will probably come with air conditioning as standard. We assume that it is only useful to keep us cool on a hot day. So why is it standard here in England; we don’t enjoy the hottest of temperatures do we?

Well air conditioning can help in other ways too. It quickly demists your windscreen, filters out airborne particles (like dust and pollen) to make the air ‘purer’ and, on that elusive hot day, helps to keep the temperature in your car down and the aerodynamics unaffected (which wouldn’t be the case if you had to open your window).

Like everything else under the bonnet, the air conditioning system needs servicing to keep it working effectively and efficiently. Although the technology has come a long way since the original system which was first used in the 1940s, it still needs to be maintained. Air conditioning repairs can be very costly, so having your system serviced regularly can help you avoid large bills later on.

It is a very complicated system with quite a few components: a compressor, condenser, evaporator, orifice tube, expansion valve and accumulator (amongst other things) – so don’t try a DIY service at home!

All air conditioning systems will leak refrigerant over a period of time, and if this is allowed to continue, can seriously affect the compressor (the main and most costly part of your system). If it is not repaired by an expert it could cause further damage and, in extreme cases, lead to your car breaking down.

Despite the lack of hot weather, you should use your air conditioning all year to ensure the refrigerant and oil are circulated round the system; this makes it harder for bacteria to grow and keeps the seals lubricated.  That musty odour you can get is a common complaint – it can smell of anything, from stale air to babies’ nappies. It’s caused by the mould which can build up in the evaporator, a perfect home for bacteria, but can easily be remedied during the air conditioning service.

The John Austin air conditioning service costs £78, but we’ve just launched a new loyalty scheme where you could get this for FREE*. If you’re one of the unlucky few who doesn’t have air conditioning, then you can give it to a friend or relative to use – I’m sure they’ll be pleased to have their system serviced for free.  You can collect your loyalty card from the garage today.
