UV Leak Detection: Finding Your Car's Aircon Leaks

Refrigerant gas is invisible, which makes finding a leak a significant challenge. Simply refilling a leaking system is a waste of money and harmful to the environment. At AC Regas, we don't guess—we use a proven, scientific method called UV Leak Detection to find the exact source of the problem.

How UV Leak Detection Works

The process is simple but incredibly effective:

1. Dye Injection: We inject a small amount of a highly concentrated, oil-soluble fluorescent dye into the AC system along with the refrigerant gas and oil. This dye is completely safe for all AC components.
2. Circulation: You drive your car as normal for a day or two. As the refrigerant circulates, the dye mixes with the oil and escapes from the same tiny crack, hole, or failing seal that the gas is leaking from.
3. Inspection: You bring the car back to our workshop. In a dark bay, we use a powerful UV (ultraviolet) blacklight to inspect every component of the AC system—pipes, hoses, the compressor, and the condenser.
4. Pinpoint Accuracy: The escaped dye reacts to the UV light and glows a brilliant, unmistakable fluorescent green. This allows us to see the exact location of the leak, whether it's a pinhole in a pipe or a worn-out O-ring, and quote you accurately for the repair.

This method removes all guesswork and ensures we fix the problem correctly the first time.
