Your car’s air conditioning system isn’t just for keeping you cool on bright, sunny days. If anything, it’s just as valuable in winter, helping to demist your windows and windscreen on those cold winter mornings.
Most car manufacturers recommend having your air conditioning system serviced every two years. This is because your aircon system naturally leaks around 10% of its refrigerant gas every year, so even with a service every two years, it could still have lost 20% of its gas to unwanted leakage, causing a loss of efficiency.
