Looking for leaks an HVAC tech can spend hours on. Sometimes even with the most expensive electronic testers may not find the leak. We also have many bubble solutions to choose from to find the leaks. They are not all equal and some are better than others. Here I am checking a few leak bubble solutions out. They all worked on bubbling up on this leak. I even show how a cleaning product Windex performs on this refrigerant leak. I use Big Blue, Cal-Blue, Diversitec Pro Bubble, and Windex. You can decide which is the best one in this video.
