Air conditioning systems on vehicles are designed to provide the driver and the passengers some relief from hot weather conditions. It was made to make a trip more comfortable during uncomfortably warm, humid or hot trips. Vehicles in hot climate are often installed with an air conditioning system. However, like all other car parts, it wears off and eventually needs to be repaired.

Air conditioners were basically created to remove hot air and replace it with cooler air. The principle that air conditioners apply is conduction and convection. Basically, the evaporator of the air conditioner removes the heat from the air when it passes through it until it is forced through the vents by the blower meter. The different parts of the air conditioning system may suffer from wear and tear caused by a number of factors, and in order for it to operate properly, it has to be repaired.

Many car repair shops in Australia provide air conditioning repair or replacement. Usually, the mechanic will give the customer a quote of the price before or after the analysis of the unit. The repair of the air conditioning system takes a few hours to a few days depending on the condition of the unit and the demands of the customer. Usually, faulty air conditioning systems are replaced with new ones to avoid inconveniences on the part of the owner especially when he or she does not have the time.

The Australian Automotive Aftermarket Association (AAAA) is concerned with the manufacturing, re-manufacturing, wholesaling, distribution and retailing of all vehicle parts, accessories, tools, equipment and services including that of four-wheel drive vehicles.
There has been some criticism about the use of air conditioners on cars and its effects on the depletion of the ozone layer. Chloroflourocarbon, an organic compound that causes the depletion of the ozone layer, is usually emitted by air conditioners.

But technology has improved over the years and an environmentally friendly air conditioner has been developed that emits very little to no dangerous pollutants at all. Most cars today use a new refrigerant called R-134A, which contains no chlorine.
Air conditioners today have an automatic temperature control set-up system which makes it more dependable than the previous vacuum and thermostatic creations. Computers ensure the comfort of the car's occupants by maintaining the right temperature inside the car.

The two main organizations that represent the interests of the air conditioning and heating industries to all levels of government in Australia are: the Australian Institute of Refrigeration, Airconditioning and Heating (AIRAH); and the Airconditioning and Mechanical Contractors Association of Australia (AMCA).
