I am having my 15 year old Rheem unit replaced. TXV gone bad and coils very rusty. The Model number is RPGB036JAS.
The old unit cooled and heated fine, except on the coldest of days when the heat strips would kick in (only a couple times throughout the entire winter).
My installer said he is putting in a 3.5 ton unit.
But isn't this model number for a 3.0 ton unit?
Should I question him on this?
