Trane

Footprint (in inches): 40 (h) by 17.5 to 24.5 (w) by 28.5 (d).

Serviceability features: Integrated furnace control monitors system status and has self-diagnostic capability with built-in LED fault code display. Variable-speed blower cfm LED provides visual confirmation of selected heating, cooling, and cfm settings. Components and controls positioned for easy installation, access, and service.

Technical support: All Trane distributors have a dedicated field service rep who provides local technical support and training.

Noise-reduction features: The soft-start feature of the variable-speed blower motor keeps audible startup noise to a minimum. The overall operating sound level remains extremely low during first-stage operation due to the reduced firing rate and lower operating speeds of the induced-draft and variable-speed blower motors. The fully insulated furnace cabinet also plays a key role in minimizing operating noise. The addition of automotive-grade gaskets to the blower compartment doors reduces the infiltration of unconditioned air.

Humidity-control features: Comfort-R cooling mode allows the evaporator to rapidly cool down by staging airflow during the cooling cycle, resulting in increased moisture removal. The XV90 is factory wired for optional humidifiers and electronic air cleaners. Field connection leads are labeled for easy identification.

Additional features: The furnace has a new hinging blower door with easy-opening, quarter-turn latches. The hinged door keeps the homeowner from installing the doors incorrectly. The hinge design allows quick removal of the blower door for service without the use of any tools. A new, internally mounted, spring-loaded filter rack can be installed for either bottom or side return air applications and automatically adjusts to accept off-the-shell filters. The furnace control uses silicon nitride hot surface igniter with adaptive heat up, increasing the life of the igniter by constantly monitoring and adjusting the voltage to the igniter, ensuring that it does not overheat. The capability to adjust the voltage to the igniter also means that the furnace has improved chances of operating during low voltage or “brown out” conditions.
