Can someone tell me the best/easiest way to find leaks on a residential A/C system (R-22). I am sure it is not leaking thru the valves. Thank you
electronic detector! = $$$$$
when calibrated with new sensor, can find equivalent of 1 bubble per 6 months of coil in a bath of water
harvest rainwater,make SHADE,R75/50/30= roof/wall/floor, use HVAC mastic,caulk all wall seams!
Electronic detector, and Big Blue.

How many times must one fix something before it is fixed?
My favorite is the yellow jacket UV light. I've yet to have a leak that I couldn't find with that thing. A lot of guys in our shop hate the thing, but try it if you have access to one.
