Leading independent extended warranty specialist, Warranty Direct, says too many drivers switch off their air con during the winter leaving it prone to failure when the warmer weather returns.
Duncan McClure Fisher of Warranty Direct explains: “Switched off for long periods of time, water or air can get into the system. The moisture will react with the refrigerant to create acid, which then attacks the seals and pipe-work leaving you with a hefty repair bill.”
Data shows that air-conditioning units account for 1 in 20 mechanical failures with an average bill of £583 but as high as £1,661.
Air con is also no longer the luxury it once was. Experts estimate that almost four out of five new cars now come fitted with the cooling system as standard.
As well as regular use throughout the year, Warranty Direct also recommends annual maintenance checks which cost as little as £40 from an independent specialist.
