During the hotter summer months motorists use the Air-Con system more; however your system is also useful in winter. Air-Con systems create dry warm air rather than the normal humid air from outside and this de-mists your car windscreen more quickly.
Many new vehicles sold are fitted with air conditioning and climate control systems as standard. We will use Air-con in our car on both hot and cold days, but not many people are aware that like other parts of your car, the air-conditioning system also needs regular attention to make sure it is working efficiently.
Over 10% of air-con gas permeates from the air-con system every year, which means that it may not work as well as it should. This is why car manufacturers recommend your Air-Con system is recharged with gas and lubricant every 2 years. This service is not part of routine vehicle servicing, so if your vehicle is more than 2 years old it's probably due a recharge.
Air-Con systems not fully recharged will be less effective and have to work harder putting more strain on the engine and using more fuel. If your Air-Con system has not been recharged in 2 years it will dramatically reduce efficiency.
