Trane XL90 Furnace Overview

Trane’s XL90 is a two-stage gas furnace with a 92%+ AFUE rating. Two-stage heating lets consumers choose different settings depending on whether the temp is just a little nippy or well below zero. Other features on the XL90 include Trane CleanEffects™ which takes care of air filtration along with the heating. This model comes with a four-speed blower, a self-diagnostic microelectronic controller, and an adaptive silicon nitride igniter.

The Trane XL90 gas furnace comes in a convenient pre-painted galvanized steel cabinet of 40″ by 28″ dimensions. In addition to the usual vertical positioning, it can also be installed horizontally. Other features include a washable filter, one-piece heat exchanger that requires no welding, electro-deposition paint, and an enclosed burner box.
