The installation is VERY different. My current furnace is in a 21 inch deep pit in my garage. It sits on the floor, coil above that, supply above that, return above that. No space between any of these.
Contractor A wants to move my furnace over (out from under the supply/return ducts), install a base can to get it up to 18 inches above the main garage floor, then coil, then furnace (Trane XV95). Having the return come over the top with a curved duct. The supply will come out of the bottom and curve around to meet the supply in the wall. Free 10 year parts, 5 year labor warranty.
Contractor B wants to hang the furnace (Bryant Preferred 96t – model 926T) horizontally from the garage rafters near where it currently is. Using curved ducts to reach the current supply / return ducts coming out of my wall. 10 year parts, 1 year labor warranty.
Which do you think is better?
