Keeping cool isnt just good for you and your passengers, it also benefits your wallet! When your air conditioner refrigerant is low, the air-con system struggles to cool air efficiently and so begins to work harder, consequently using more fuel.
Failing to keep the refridgerant topped up can also lead to more costly repairs down the road as it also serves to keep the air con compressor cool. A lack of refrigerant can contribute to the compressor failing due to overheating.
Air conditioning even has its uses on cold winter days. As well as it helping demist your windows, it also enures effective working of the system when the outside temperature starts to get nice and warm again.
