Car Air Conditioning Service No Gas in System.

Important:- Nitrogen Leak testing will show 90% of leaks, but in 10% of cars with no gas present at the time of service it is virtually impossible to detect a porous leak, as nitrogen molecules are 10 times larger than the refrigerant. This is why we put UV dye in cars with no gas, so if in the rare circumstance your car loses all the gas, we can locate the source of the leak. As we use OFN Nitrogen to pressure test cars we can diagnose most leaks, unlike most garages that do not offer this service. It is industry standard that porous leaks can not be detected.


If we find a leak and are not able to re-gas your car we will only charge £15 for our time and nitrogen gas.


When testing your vehicle and we find there is no gas present at all in your system, and it passes the nitrogen leak test. We recommend putting in Extreme Leak Seal to prevent your system from leaking in the future and to cure any porous leaks that may be present that caused you to lose gas in the first instance. Please look at the video below for more information on how it works



When we test your car and find you have no gas in the system we charge £10 for a Nitrogen test leak and spray a bubble solution on the condenser and pipes to highlight any potential leaks in your system. We also add UV dye to show future leaks. 

The test will not detect rare "High-Pressure Porous Leaks"  This is because Nitrogen molecules are 10 times bigger than the refrigerant molecules and the Nitrogen test can only pressurize to 150psi. On a hot day, your car reaches pressures of over 300psi, which can cause the refrigerant to leak, due to potential high-pressure that the nitrogen test cannot detect.


Adding an Extreme leak sealer will rectify 80% of leaks, but when the AC system reaches high pressures, holes can then expand above 0.3mm which the sealer may not repair. We can only check the visible components of the AC system.


We believe the customer must be informed of the above information before deciding whether to have a regas or adding Extreme Leak Sealer. We only charge £15 if you decide not to have your car regassed and we will tell you what part needs replacing to rectify the problem.

Coronavirus update: We are still trading, but we ask customers to either stay in their car or stand at the rear of their car. You may pay by cash or use our contactless payment system, which will be cleaned after each use.
