Ok, got it now.
Good on ya for giving a Vet a break.
I haven't done HVAC work in years, but I was digging in the shed the other day and found a brand new, unopened 30 lb of R-22 I didn't even know I had.
I just paid close to $800.00 for another jug yesterday,atleast the price has come back down a little.
I remember bitching when the price went up to like $50.00 a jug from $25.00 years ago,I kicked and hitched and moaned back then.
If only I had known!
It's funny how jobs done in different locations than someone nornally works can look "wrong". Even though that's an upflow furnace with the coil on the positive pressure side of the blower, it would fail around here without a condensate P-trap and the proper PTFE joint tape.
