The Trane XE 90 furnace has an AFUE rating of more than 90 percent, meaning that 90 percent of the fuel you use is directly turned into heat. This gas furnace has a patented heat exchanger that is designed with a serpentine-shaped channel. When air flows over the heat exchanger, hot gases are pulled through the channel by an induction vent fan, rather than escaping up the flue. According to the manufacturer, then thin exchanger features low air flow resistance, which in turn means that there is less work for the blower motor.
The Trane XE 90 has a self-diagnosis capability that utilizes a controller search system to identify any problems that need to be resolved. When there is a power or fuel interruption, the system is designed to reset automatically.
The unit is available in upflow and downflow models. The hot surface igniter replaces a pilot light. A heavy-duty, fully insulated steel cabinet was designed to reduce noise and further lower heat loss. The manufacturer also notes that the unit’s 40-inch high and 28-inch deep cabinet was designed to fit nearly any space.
