Car Air-conditioner Test & Inspection Service From $70
If your air-conditioner is not cooling as it should then you most likely have a refrigerant gas leak. The diagram above will give you some idea of the complexity of identifying a leak in so many components with so many hoses, joins, seals and fittings to go wrong.
Rest assured, the specialist technicians at Highway Auto are the best in the business with wide and varied experience in automotive air-conditioning systems. Your vehicle will be checked for leaks first and foremost because its a bit like a punctured tyre, the leak must be repaired before the process of recharging the system so that evaluation can proceed.
Ring Steve now on his direct line (07) 49261303 and make arrangements to have your car or 4X4 air-conditioner performance evaluated.
About your health and vehicle air-conditioning
Due to the very nature of vehicle air-conditioning it is a potential harbour for fungi, mould and various bacteria. The air-conditioner evaporator is where these nasty creatures gather. The damp of the evaporator causes airborne particles to stick and ultimately provide a breeding place for all things smelly and unhealthy. There is a cabin air filter in most modern vehicles but sadly it is mostly overlooked during scheduled servicing. If the filter has been replaced every 12 months then your evaporator may still be okay, otherwise it may be necessary to remove it and physically scrub the rubbish off it and disinfect it.
Car Air-conditioner Cabin Filter
Unfiltered air inside a vehicle contains minuscule pollutants that can aggravate respiratory problems including asthma.
Sufferers of asthma, allergy and other respiratory problems are especially at risk when concentrations of pollutants are elevated inside the vehicle.
Contaminants in the air such as pollen, fungus spores, dirt and dust pass unfiltered into the passenger cabin, along with the air intake and can trigger asthma, allergies, headaches, nausea, fatigue and giddiness. Is your car making you sick...?
Cabin Air Filters, are designed to reduce the amount of harmful contaminants entering into your vehicle via the heating ventilation and air conditioning (HVAC) system, whilst providing a much cleaner breathing environment for you and your passengers.
Replacing Your Cabin Air Filter
Cabin air filters should be changed every 12,000kms or at least once a year. When the cabin air filter clogs up with dirt and other contaminants, the airflow entering the vehicle's interior is significantly reduced. Over time, the clogged filter can lead to musty odours as well as decreasing the HVAC's performance.
(Asthma, Hay fever)
Protects vehicle occupants from allergy causing particles such as pollens, fungus spores, dirt, dust and bacteria.
CLEANER VEHICLE INTERIOR
Filters out dirt and dust, which build up on the vehicle's interior surfaces.
Offers protection from respirable particles that lead to respiratory problems, headaches, nausea, fatigue & giddiness.
ABSORPTION OF GASES & ODOURS
Protects vehicle occupants from harmful gases such as exhaust and ozone. Filters out noxious odours. Applies to Activated Carbon Filters only.
Car Air Conditioner Maintenance
Tips on having trouble free functioning of your car and 4X4 air-conditioning system
Maintaining your vehicle's air-conditioning system means that you will always have cold air and minimise the chance of expensive air-conditioner repairs later on.
Small leaks in the vehicle’s air conditioning system allow the refrigerant to escape and the system can’t cool the air as well or perhaps not at all.
The obvious faults which are associated with an Air Conditioning systems breaking down are:
Anything beyond this visual inspection then requires a full Air Conditioning Service. Only a fully qualified air conditioning technician can carry out this service. Highway Auto is a certified air conditioning repairer and can carry out all necessary repairs to get your air vehicles conditioner working to its optima performance Check out our license at Australian Refrigeration Council
- Poor drive belt tension
- Restricted 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
- Fouled evaporator restricting airflow
Tips For Maintaining A Car Air Conditioner
Running the air conditioner once a week for 10 minutes will maintain the gas pressure. This prevents hardening of the hoses and compressor seals failure. Turn the air conditioner to its coolest 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 dirty wet cloth odour in the system.
Remember your air conditioning system does not only cool your vehicle but in addition one of its primary functions is to remove the humidity from the cabin. So it is good practice to use your air conditioner in winter to keep your windscreen free of fog which impairs your visibility.
By allowing all car windows to remain closed, even on the hottest days, the aerodynamics of the car remain at optimum, keeping fuel consumption low and exterior noise to a minimum, increasing safety to the driver and passengers.
You may not be aware that over 10% of air-con gas permeates from the air-con system every year, which means that it may not work as well as it should. This is why car manufacturers recommend your Air-Con system is recharged with gas and lubricant every 2 years.
It is good practice to get a full air conditioning service at least every two years. Try and do this before the hotter month’s start, as this will ensure that you are not caught out by a sudden heat wave at the start of the season.
This will enable you to keep ahead of any system faults or potential compressor failure.
A poorly maintained system operating on a low amount of oil and gas will reduce your compressors capacity to run efficiently costing you extra in fuel.
