Nitrogen Leak Testing

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 £10 fee also includes a free check under UV light if the gas escapes, and we only charge a £15 service charge plus gas if your car needs regassing, within 3 months, due to a leak.

 

Important Information.

A nitrogen leak test will identify 90% of leaks. The test will not detect "High-Pressure Porous Leaks"  This is because Nitrogen molecules are 10 times bigger than the refrigerant molecules and  Nitrogen 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 porous leaks, that the nitrogen test cannot detect.
