How do you find freon leaks in ac system?

To find freon leaks in an AC system, you can use a few methods. A common approach involves applying a soapy water solution to potential leak points, such as joints and connections; bubbles will form if there’s a leak. Another effective method is using an electronic leak detector, which can sense refrigerant gases in the air. Additionally, UV dye can be added to the system; a UV light will reveal the dye at the leak site.
