Trane A801X026AM2SA Gas Furnace 26000 Btuh Single Stage Upflow Horizontal

Product Description

The Trane A801X026AM2SA is an 80% AFUE induced draft gas furnace designed for upflow and horizontal installation in residential forced-air heating systems. Carrying a nominal heating input of 26,000 BTUH, this single-stage furnace delivers consistent heat output through a standard induced draft configuration. The A801X026AM2SA is built as an OEM-grade unit intended for professional installation by licensed HVAC technicians. Its compact cabinet design suits tight mechanical spaces while maintaining the performance standards expected from the Trane product line.

This furnace is suited for residential applications where a lower-capacity gas furnace is required. Upflow orientation directs conditioned air upward through the supply plenum, making it a practical fit for basement, closet, and utility room installations where the air handler sits below the duct system. Horizontal orientation capability extends installation flexibility to attic and crawlspace applications. The single-stage heat operation pairs well with standard thermostat controls in straightforward residential retrofit and new-construction scenarios.
