Auto Air Conditioning
Frequently Asked Questions

It is a good idea to have the a/c serviced regularly. Annual services are recommended. This will mean fewer breakdowns and should give your system a longer working life.The receiver drier, which is the filter of the a/c system, should be replaced every two years (in accordance with the manufacturers’ specifications) or if the system has been opened for some reason. 

No. Our team is trained to complete regassing and other services safely and competently. Not only is the refrigerant in your A/C system a hazard, but a certain level of skill is necessary for navigating the electrical systems inside your vehicle. 

There are several key steps you can take to keep your air conditioning working well between services. This includes running it regularly to keep the system fresh, cleaning the filters to prevent germ build-up and keeping windows closed when you use the air conditioning, so it doesn’t work overtime.  

The system is tested for leaks. If no leaks are found, the old gas is evacuated and regassed with 134A gas. The receiver drier may be changed, depending on how old it is and whether the system has been open.  

This varies according to the type of car and the position of the leak. Some leaks are easily detected, while others take a while to find. As a result, it is best to leave the car for at least half a day, if possible, especially during busy periods. 

In hot climates like Australia’s, it’s important to always keep your vehicle air conditioning in good working order. During long drives in summer, heat can build up inside your vehicle and cause the interior of your car to become uncomfortably warm, and this can also dry the air out inside your car. If you ever drive elderly people or children, they are also much more vulnerable to the effects of dehydration or even heat stroke.

If your air conditioning isn’t working as it should, it’s important to see a professional auto air conditioning engineer as soon as possible to prevent the risk of accidents during your next long drive. 

If your car air conditioning isn’t working at all, it’s clear that you need to contact a specialist for repairs. But there are also other signs that your air conditioning isn’t working properly and could stop working altogether soon. Some of the most common signs that your vehicle’s air conditioning needs repairs include:

  • Car A/C is blowing warm or only slightly cool air.
  • The airflow coming from the A/C is weak.
  • A/C starts blowing cool air but gradually gets warmer.


There are various issues that can cause all these faults, including problems with your compressor, hose, or expansion valve, and these issues can also be caused by blockages somewhere within the car’s A/C system.

The first clue that your air conditioner needs to be re-gassed is that the air coming out of the vents isn’t as cool as it used to be. Foul smells and strange noises from the system are also notable warning signs. 

The most common reason for an air conditioner not getting cold enough is that it has run out of Freon and must be refilled. If you have re-gassed your air conditioner in the recent past and the issue persists, there might be a leak that needs to be taken care of. 

While applying DIY repairs to a faulty car air conditioner is possible, it only provides a temporary solution to the issue. Our team of experts can diagnose your faulty car AC and repair it to continue providing comfort in the long term.
