If you feel that your car doesn't feel as cold as it used too, or if it hasn't been serviced within the last two years then your car Air Conditioning may need servicing. The air conditioning system in your vehicle is not covered by any manufacturer's service schedules and the refrigerant gas that is used to operate the system depletes over time. On average most cars lose up to 15% per annum, even more if a leak exists resulting in gradual deterioration in system performance until finally on a stinking hot day the system will not function at all.
Just as the other systems of your car need servicing on a regular basis, the same is true for the car air conditioning system. If not maintained, the performance of your car's air conditioning will deteriorate and will cease working entirely (probably when you need most). Regular servicing of your car's air conditioning system will keep it operating year round in peak performance guaranteeing your comfort, even in the hottest months.
