Stainless steel tubing for AC lines?
Wading a bit out of my knowledge zone here. I recently acquired a lot of stainless steel tubing. Like miles of it lol. 1/4"-1" in various wall thicknesses but for example I have a 2200' of 3/8" 0.035" 316/316L Sandvik instrument tubing with lots of accompanying Swagelok fittings.
My thought is that it is completely overkill for the application of plumbing a split AC system I have in a guest house, but suffice to say it was almost free.
I'm not a HVAC expert, nor licensed to perform AC activities. But I am fairly well versed in mechanical things and running, bending, flaring and hooking up lines is well within my wheelhouse. And I like to do things myself.
The AC condenser at this guest house/barn has been in place since the 70's and I would like to retire it. It may run a few weeks in the summer and that's it, I close the place down in the winter.
Good or bad idea?
