The following components are tested:

Car Aircon refigerant gas leaks and detection methods

A leakage of refrigerant in an HVAC system is inevitable as there are many imperfect joint fitting hoses or welding points. We know the likely weak points but that is not enough to ensure total leak detection.

Here at Highway Auto Car Air-conditioning, we are fully equipped with the latest state of the art vehicle air conditioning system servicing equipment and our technicians have ongoing specialised training.

Some leak loss situations can be as low as 1 gram every decade and are not critical to the operation of the system. Others may leak more due to harsh temperatures, environment, and vibration that cause these joints to leak. If not rectified, these defects will cause the cooling system to drop in efficiency and eventually stop working.

We will not regas your air-conditioning system knowing you have a leak, as this is illegal and will result in unnecessary future re-gassing along with harm to the environment. Whether this is a small leak or a large leak Highway Auto Air have numerous ways to detect leaks through multiple techniques.

Dry nitrogen pressure testing and Spray on bubble type leak detection

Fluids allow accurate pinpointing of car air con leaks as the user can watch bubbles or foam actively brew at the point of leakage.

Ultrasonic leak detection

Ultrasonic sound is a range of sound (>20kHz) that is above the human hearing capacity. Turbulence created by air or gas forced through a small orifice generates ultrasonic sound. Ultrasonic leak detection is also used to locate leaks in systems pressurized with dry nitrogen.

UV Leak Detection

UV trace detector dye provides safe, fast and precise detection of small refrigerant gas leaks from air conditioning systems. Once uv dye is added to the system the dye will fluoresce under illumination with a UV torch wherever there is a refrigerant leak. This precisely locates the leak resulting in extremely accurate leak detection.

Electronic gas detecting machines

This refrigerant leak detection is the most favorable used device due to its accuracy using an infrared sensor to accurately detect leaks

Recently had my Mazda air con fixed, it cost half the price of what the dealer quoted and was done the same day, same day service was very important as I need my car for my business. Great Customer service and a better price! Got referred by friends and happy I did.

Great Customer service and an even better price!

- Ellen Kawana

Fantastic business and a pleasure to deal with. AC system on my ’08 Golf was failing and after attempts at replacing valves, gaskets and recharges from other workshops, it was still not cooling. Highway Auto identified the problem immediately and quoted me on repairs. Luckily the vehicle was still covered under an extended warranty policy, and Steve (who is knowledgeable, helpful and polite) dealt with the insurance company directly to have the vehicle’s entire AC system replaced.
