An air conditioning recharge, or regas, is a process which involves removing any old refrigerant gas and oil from your air conditioning system. This will allow the air to start blowing cold again, as the correct amount of new refrigerant and lubricant is replaced into your air conditioning system.
Vehicle owners may not realise that air conditioning gas leaks and wears out with use. Around 20% of the gas over a year is naturally lost due to the porous components in the system. A drop in gas pressure means a drop in air-cooling ability, which will make your engine work harder – therefore, your vehicle uses more fuel. If you allow the system to run low, the compressor has to work twice as hard and will then wear out in half the time due to lack of lubrication.
