Over two-thirds of modern vehicles in the UK are fitted with air conditioning and climate control systems as standard. Many people use air conditioning regularly in their vehicles so as to be more comfortable in hot weather and also to help de-mist their windscreen in cold weather.
You may not, however, be aware that a percentage of refrigerant is lost from your vehicle’s air conditioning system each year. This then allows a build-up of fungus and bacteria. You may notice a peculiar smell coming through the vehicle’s air vents and that can sometimes lead (in extreme cases) to an allergic reaction.
Systems that are not fully re-charged put more strain on the engine, which consequently uses more fuel whilst running. Car manufacturers recommend your air conditioning system is re-charged with gas and lubricant every 2 years in order to keep it running efficiently and economically.
