Helium is best option for testing leaks. If the leak cannot be detected with the air conditioning system switched off, start the engine and operate the system to build up system pressure. If you have a license and certification you can still purchase this, though most people opt to retrofit this system to the newer R-134A refrigerant. The evaporator is located inside the dash of the vehicle and is used to absorb heat from the interior of the car. Observe the gauge on the kit and begin adding the refrigerant whether it be with a button or a trigger on the kit. Ensure that the high and low pressure gauges have equalised. Repairs covered by 12-month/12,000-mile warranty. Typically, all systems today contain R-134A refrigerant. In pressure-testing, you use a moisture-free inert gas to pressurize the A/C system. Shine the ultraviolet lamp around the suspected areas. Step 1: Park your vehicle on a level surface. You can pressurize to well over 100PSI so that the R22 will be forced out of any leak present. Below are the most common causes of poor air conditioning performance and what can be done to get you comfortably back on the road.
