Car Air Conditioning Tips

If you want to avoid sticking to your leather seats in a long hot traffic jam this summer, and demist your windows at the flick of a switch in winter, you'll need to understand how to effectively maintain your car's air conditioning system.

What is Air Conditioning?

A car air conditioning system cools the temperature inside your car and helps to filter out pollen, pollutants and airborne bacteria.

The AC system works like your fridge at home - the air is cooled with a refrigerant gas and then circulates through your car.

How to get the most from your air con?

There are a number ways you can get the most from your air con.

  1. If you are using your air con, close your windows
  2. During hot spells, it's tempting to open your windows for that extra blast of cold air (we've all been there!). However, if your windows are open and your air con is on, you're actually wasting fuel and pumping cooled air outside.

  3. Recharge regularly
  4. As with oil and other liquids in your vehicle, the coolant used by the air con system needs to be regularly refreshed (known as a recharge or re-gas). Periodically, the coolant has to be drained, refilled and key components lubricated to keep them working efficiently. Most manufacturers recommend a recharge every two years, but make sure to check your vehicle's handbook.

    If your coolant levels are reducing faster than expected, this could indicate a leak in your system. It's important to get this checked as the gases (while safer than those used in the early 1990s), are harmful to the environment.

    At Halfords Autocentre, we can recharge your air con and check for leaks as part of the service. Our highly skilled trained technicians will also lubricate all the moving parts to prolong your air con's life span.

  5. Keep your AC clean
  6. Noticing a nasty smell when using your air con? This is a common sign that your air conditioning system needs a good clean.

    Unpleasant odours are caused by a build-up of dust and liquid, creating a breeding ground for bacteria. At Halfords Autocentres, we offer an Antibacterial Clean - eradicating 99% of bacteria and leaving your air con smelling fresh as a daisy!
