How to Quickly and Easily Find AC Leaks Under Vacuum: A Step-by-Step Guide
To find an AC leak under vacuum, you need to follow a few steps. First, attach a vacuum pump to the AC service port and evacuate the system. Next, turn off the pump and observe the gauges to see if the system holds the vacuum. If not, there may be a leak. Then, introduce a fluorescent dye into the system and run the AC for a while. Finally, use a black light to inspect the AC system for leaks. The dye will glow, indicating the location of the leak.
