Key Features

♨ 96% AFUE Efficiency

• 96% Annual Fuel Utilization Efficiency (AFUE) — very high efficiency that reduces heating costs and meets current energy standards for residential furnaces.

• Helps lower annual operating costs over lower-efficiency units. Oxbox HVAC Shop

Two-Stage Heating

• Two-stage gas valve provides two levels of heat output:

  • Low stage for mild weather (longer run times, quieter, more even temperatures)

  • High stage for very cold conditions.

• Provides more consistent comfort and fewer temperature swings than single-stage units. Trane Technologies

Cabinet & Installation

• D-cabinet width (~24.5″) — wider cabinet for higher airflow capacity and easier integration with larger duct systems.

• U in the model code indicates Upflow / horizontal installation capability (both right and left airflow options).

• Designed for flexible installation in attics, basements, closets, or utility rooms where space and duct layout demand versatile configuration. Trane Technologies
