Here in Wellington, we believe that you should regas and service your car air conditioning system every 18 months or 2 years with new gas and lubricant to keep it running efficiently all year round. Generally, the aircon system will lose 10-15% of its refrigerant gas every year, which will result in a reduced cooling effect and possible shutdown of the system when the gas pressure falls below a certain level.
An aircon regas with Wellington MOT & Service Centre involves removing the old refrigerant gas from your system before replenishing it under vacuum with fresh refrigerant, leak sealing and detection agent and compressor lubricating oil. This method ensures no air is injected into the system which can cause problems later on
