    Vehicle Air Conditioning Maintenance Tips

    How to ensure an extended, trouble-free operation of your car’s air conditioning system

    Vehicle Air Conditioning Maintenance Tips

    Maintaining your vehicles air conditioning system means that you always have enough refrigerant to do the job properly.

    Small leaks in the vehicle’s air conditioning system allow the refrigerant to escape and the system cannot cool the air as well.


    Keepin Cool recommends that you regularly check your vehicles air conditioner system.


    The apparent faults, which are associated with an Air Conditioning systems breaking down, are:

    • The drive belt tension
    • Blocked air flow through the Condenser and Radiator
    • Visible signs of Refrigerant oil stain at the compressor, hoses, pipes or fittings
    • Loose or faulty compressor mounting brackets
    • Service port caps missing


    Anything beyond this visual inspection then requires a full Air Conditioning Service.  Only a fully qualified air conditioning technician can carry out this service. Keepin’ Cool is a certified air conditioning repairer and can carry out all necessary repairs to get your vehicles air conditioner working to its optimal performance.

    Tips For Maintaining A Car Air Conditioner

    Running the vehicles air conditioner once a week for 10 minutes will maintain the gas pressure. This prevents hardening of the hoses and compressor seals to leak. Turn the air conditioner to its coldest setting and highest fan speed. Run the ‘defrost’ mode for five to ten minutes to clean out accumulated moisture. This prevents mildew and prevents that nasty wet cloth odour in the system.


    Remember your air conditioning system does not only cool your vehicle but also, one of its primary functions is to remove the humidity from the cabin. Therefore, it is good practice to use your air conditioner in winter to keep your windscreen free of fog that impairs your visibility.


    By allowing all car windows to remain closed, even on the hottest days, the aerodynamics of the car continues at optimum, keeping fuel consumption low and exterior noise to a minimum, increasing safety to the driver and passengers.

    You may not know that over 10% of air-con gas permeates from the air-con system every year, so it may not work and it should. Therefore, car manufacturers recommend your Air-Con system recharged with gas and lubricant every two years.


    It is excellent practice to get a full air conditioning service at least every two years. Try to do this before the hotter month’s start, as this will ensure that it does not catch you out by a sudden heat wave at the beginning of the season.


    This will enable you to keep ahead of any system faults or potential compressor failures.


    A poorly maintained air conditioner system, operating on a paltry amount of oil and gas, will reduce your compressors capacity to run efficiently costing you extra in fuel.

    Maintaining A Healthy State For Your Car Air-Conditioning

    A car air-conditioning system can be a breeding ground for harmful bacteria and fungus. This is particularly important for sufferers of asthma or allergies.


    At Keepin’ Cool, we have the latest Ozone machine to carry out this service. We can treat the cooling evaporator also the cabin air filter and the entire car interior, killing all the bugs, leaving your car air conditioning smelling fresh.


    This treatment is designed to protect you and your passengers from the musty odour that can occur from the air conditioner vents. For more information click here

    Protecting The Environment

    Refrigerant gas like R12 and R134a are incredibly damaging to the ozone layer, and any gas that is irresponsibly released into the atmosphere by owner’s or backyard mechanics can harm the environment and contribute to global warming.

    Keepin Cool offer’s a CAR REFRIGERATION RECOVERY SERVICE for those who are doing their air conditioning repairs.

    Releasing Refrigerant gases into the Atmosphere is illegal. The penalty for this runs into several Thousand Dollars.


    By law, refrigerant gas R12 and R134a must be reclaimed and sent to bodies such as Refrigerant Reclaim Australia to be destruction by particular methods saving our ozone.


    It is now by Law that anyone that works on Automotive Air Conditioning systems throughout all States and Territories of Australia must have a Refrigerant Handling Licence.


    As a result, a Licenced Automotive Air Conditioning Workshop must display their Trading Authorisation and Refrigerant Handling Licences at all times. See Australian Refrigeration Council for more information.
