Air Conditioning and climate control systems work the same as a fridge; the compressor pumps the liquid R134a refrigerant around the system., so much that the liquid heats up, it then passes through the radiator (condenser) at the front of the vehicle to cool it, it then compresses the liquid refrigerant so much that as it is passed through either a fixed orifice tube or THC valve, it turns to gas causing super cooling in the system, this then passes through a small radiator (evaporator) inside the vehicle, the chilled air is then blown through this evaporator up thought the heater ducts in to the vehicle.
The compressor is a vital component which can be very expensive to replace. The pump relies on oil in the system to keep lubricated much the same as an engine does. This is why we recommend an A/C system service every 24,000 miles or 2 years including changing the pollen filter. We also recommend that every 24,000 miles or 2 years you have passenger cabin antibacterial service carried out, this service kills all the harmful bacteria that’s growing in the heater ducts, this bacteria can cause colds, flu or even legionnaires disease.
We use a Bosch ACS650 fully automatic air con machine to re-gas and service the system Nitrogen pressure testing to trace leaks in the system Mastercool & Loktrace tools to offer repair of metal & rubber pipes sometimes in situ instead of removing, purchasing and re-fitting expensive dealer parts.
You can use you’re A/C system on the hot setting to, this helps to de-mist the car much quicker, the evaporator attracts all the moisture in the air in much the same was a cold glass of water does on a summers day. Also using this system briefly every day keeps the seals in the system lubricated not allowing the gas to leak out over the winter.
