I found out where my AC unit is losing R-22. There is a tiny pinhole leak at a coupling on the low side copper pipe, about 8" from the compressor.
What's the best way to fix this? Is brazing the only option? The hole is so small that a full charge on the unit lasts about a month.
I'd like to get a pro to perform the repair, but i dont want to be taken for a ride. I had already called someone in a few years ago, and of course "i need a new system". Tired of the "pros" trying to take advantage of people. This time around I am going to tell THEM what I want done and ask for a quote.
I suspect I need them to braze that hole, but would they first need to recover the refrigerant, fill the line with nitrogen, braze, then vacuum out the nitrogen and refill the *****? Is there any other way around this? (i.e. would a drop of solder do the trick on this very tiny hole)
