Question re: Lineset
I have been reading on these boards that it may be necessary to change the lineset when you are changing out your HVAC system. I have a proposal from a dealer to replace the HVAC system and in the proposal it says they will "replace existing refrigerant piping between the evaporator and outside unit". They are also going to install a new condensate drain line. Is one of these a lineset?
Also, I have been told I need a 2 1/2 ton system (after the dealer did a Manual J) and that I cannot get the Infinity 2 stage outside AC because they only come in even sizes (2 or 3). If I get the Infinity variable speed furnace, am I getting an inferior system by only having a performance 2 1/2 ton outside unit? As I said, I wanted the 2 stage infinity AC because the price wasn't much different with the rebate, but I was told that due to the duct size etc. 3 ton would be too big.
