Air conditioning systems operate using R134a refrigerant and lose up to 10% of this over the course of a year. The more you lose, the less efficient your system becomes and more strain is put on the components within the system. Most vehicle manufacturers therefore recommend your air conditioning system is serviced and recharged with refrigerant and lubricant every 18 months.
During the recharging process your air conditioning system is drained, leak checked, cleaned and dried. It is then recharged with refrigerant and lubricant whilst the inside of your vehicle is deodorised, which removes bacteria from the evaporator inside the vehicle and removes any odours from the vehicle.
