Air Conditioning Recharge

The recharge process is quite simple and involves removing any old refrigerant gas and oil from your air-con system before replacing this with the correct amount of new refrigerant and lubricant as per your vehicle manufacturer’s recommendation. A vacuum test is also performed to ensure there are no cracks or damage in your air-conditioning system that could cause the gas to leak out.
Within an hour the whole recharge process is completed and you will once again have refreshing cool air on demand.  Air-con systems that are not recharged regularly will be less effective and have to work harder to produce cool air. This puts more strain on the engine and uses more fuel. If your air-con system has not been recharged in the past two years it will dramatically reduce efficiency.

Air Conditioning Cleaning  

If there are bad odours coming from your air vents when you turn on your air conditioning then your car may also benefit from an air con clean, also known as a debug. Over time bacteria, mould and fungi can build up on the evaporator in your air con system which produces this unpleasant smell when switched on. In some cases this can cause sickness and respiratory problems as bacterial spores are blown into the cabin of the vehicle and breathed in by the passengers. 
We offer an air con clean to decontaminate the system and kill the bacteria within. The process involves setting off a cleaning spray or 'bomb' in the vehicle cabin which is sucked into the air vents and kills off the unwanted bacteria within, leaving your air con system clean and smelling fresh again.
