Product Description

The Trane A801X040BM2SC is a single-stage, 80% AFUE induced-draft gas furnace designed for residential heating applications. It delivers 40,000 BTU/h of heating input capacity and operates on a 24-volt control circuit with 120/1/60 power supply. The cabinet is 17.5 inches wide, making it suitable for installations where space is a consideration. This furnace supports four-way convertible airflow, allowing upflow or horizontal left and right configurations. Licensed HVAC technicians install and commission this unit as part of a split or packaged heating system.

This furnace is intended for residential installations where single-stage heating and 80% AFUE efficiency meet local code requirements. The four-way airflow flexibility accommodates a range of duct configurations, including upflow and horizontal orientations, fitting both new construction and replacement scenarios. At 40,000 BTU/h input, it is sized for smaller to mid-size residential conditioned spaces. The unit uses a conventional thermostat-compatible 24-volt control system, integrating with standard low-voltage wiring setups common in residential HVAC systems.
