Hey guys,

I am having an old Lennox air conditioner (R22)replaced with an Amana RTG 36. The new heat pump is R410A. Replacing the line set will be very problematic but could be done if necessary.

My question is..........is it necassary?

I have talked to havc guys locally and the answers are all over the map. The guy here doing the work said that he will abide by the consensus of the board.........so have at it.

From reading the board I know that there is lots of opinion out there.......LOL.
