Hi and welcome to the club :thumbsup:

AIR-CONDITIONING: What do I need to know about servicing it and can you list some specialists?

Switched off for long periods of time, water or air can get into the a/c system. The moisture will react with the refrigerant to create acid, which then attacks the seals and pipe-work leaving you with a hefty repair bill.

With a standard manually controlled a/c system you should leave the a/c on all the time, even if not using it to cool the car. You should also turn the system to full cold for ten minutes once a week – even through the winter if you can – in order to circulate refrigerant which contains lubricants for the system and its seals. Then switch to full heat through the same pipes to thoroughly dry them out. This gets rid of any moisture in the ventilation trunking where mould and bacteria might be accumulating.

Climate control systems, where the temperature is set by the operator should be left on all the time, as the a/c will be required to fine tune a reduction in temperature. The vehicle will decide for itself whether to engage the compressor or open the outside flaps and let in the outside air, which at 0 - 3c Celsius will have no moisture content anyway.

Opinions are divided on servicing. Most manufacturers say 3 years from registration or 30,000, then every two years after that. Chrysler recommends every 12 months for the Voyager, and Volkswagen now says every 24 months. Some manufacturers such as SAAB have suffered spates of compressor failures. Aircon specialists looking for business will tell you it needs servicing, preferably by a visit to an air-conditioning system specialist, every year. That way they can keep a record of how much gas is being lost from the system. But the only way to test the gas is to draw some off and lab-test it.

Re-gassing a typical air-conditioning system costs around £80 + VAT. A service and a new accumulator/dryer costs around £150 + VAT. Some a/c specialists argue that this needs to be done otherwise the silica gel desiccant in the dryer could break up and circulate through the system, severely damaging it. Refrigeration engineer Keith Wood believes that replacing the accumulator is not necessary and could be responsible for introducing harmful dirt or dust to the system. It should only be replaced if the system has lost gas and needs to be re-gassed. In his opinion the only regular checks should be for leaks. A pool of water under the car is, of course, not the result of a leak but of condensation dripping off the condenser and is entirely normal.

The two main causes of failure are lack of gas (via leaks at the system seals) and component breakdown. Low refrigerant means low lubricant, which is contained in the refrigerant, and this can lead to seals drying out, thus losing even more refrigerant and leading to failure of the compressor. Properly repairing a failed system is a four-figure job.
