Also a cars failing air conditioning system can affect its fuel performance. The reason for this is that when your air conditioning refrigerant is low, it will struggle to cool the air and so this will cause it to work much harder to try and produce cold air. This process causes the car to use more fuel.

Often a poor performing air conditioning system will give out an odour, if you suspect your air conditioning system is not quite right give us a call and we can happily check it out. Other than that it is advised to have it checked every 2 years to make sure it is performing well.
