The Trane is quieter and easier to repair than the Lennox furnace. I work on both furnaces and the Trane is easier to troubleshoot than the Lennox. Yes you can hang furnace from rafters but it is more difficult to hang the Auxilary drain pan under furnace. The 90% is much quieter than the 80% furnace. The burners are enclosed making it quieter.

Train High end 96% Afue furnace has two heat exchangers. That is what I have read. Mine are going to be placed in the attic. So it means they have to have two vent pipes going out through the roof for proper ventilation of the furnace.The furnace by Trane has sealed combustion unit. How does it help? Do you prefer Furnaces to sit on a platform in the attic than hanging through the rafters?. How do installers hang the Auxillary drain pan when they hang it through the rafters.i am comparing Lennix high end SLP98v furnace with the Trane XV95 furnace. Which one is whiter out of the two?.Thanks.

Installers hang the furnaces by metal straps from rafters. I prefer the furnace to set on a platform above drain pan. You only have to have one vent thru ceiling. A concentric vent can be used that has intake and exhaust in same pipe. Lennox has had problems with secondary heat exchangers in the past. Trane 90% and above have not had any problems. From a dealers standpoint the Trane has less problems than the Lennox.
