Advice from air-conditioning experts: Inspect your air-conditioning unit regularly to prevent "gas guzzlers"

Schwäbisch Hall, May 2011. People who look for short-term savings often pay more in the long-run. Regular inspection and servicing of air-conditioning units – experts recommend checking utility vehicles every six months – not only saves on costs and time-consuming repairs, but also reduces idle times and downtimes. Regular servicing also reduces the consumption of the air-conditioning unit.

According to thermal management experts Behr Hella Service, air-conditioning units which are not serviced properly, or not at all, are veritable "gas guzzlers". In a model analysis, experts found out that an air-conditioning unit consumed around 0.6 litres more per 100 kilometres if not serviced regularly. A vehicle that drives 125,000 kilometres each year and uses the air-conditioning unit 60 per cent of the time on average consumes up to 450 litres more fuel each year. Regular servicing not only helps reduce running costs; it also prevents high repair costs and the need for expensive spare parts if the air-conditioning system breaks down prematurely or suffers serious damage. For example, the oil circulating with the refrigerant lubricates the air-conditioning compressor. Every year, up to 10 per cent of this refrigerant escapes through natural evaporation, which can cause compressor failure due to lack of lubrication.

The evaporator can also become the cause of many problems given that it is a significant part of the air-conditioning unit. Condensation forms in its fins. Over time, bacteria, fungi and microorganisms accumulate and can endanger the driver's health. The evaporator must therefore be disinfected regularly. A functioning air-conditioning unit keeps drivers more relaxed and safer in their cars; they are more concentrated and their reflexes are better, which effectively reduces the risk of accidents.
