I have run into a few that will not service systems with puron, said
something about the higher pressures, not that many in our area for them
to
worry about it either ?



Again, my own opinion, but any contractor that refuses to work on them will
run out of work after awhile (when it comes to A/Cs and heatpumps).

Agreed, it is a PITA to have to go out and buy new equipment (just to handle
R410), but Puron is here to stay and they are going to have to work on it
sooner or later......
