Trane A801X080CM5SC Single Stage Gas Furnace 80000 Btu/h 80% Afue Multi Position Upflow Downflow Horizontal

Product Description

The Trane A801X080CM5SC is a single-stage, induced draft gas furnace rated at 80,000 BTU/h input and 64,700 BTU/h output, operating at 80% AFUE. Part of the RunTru by Trane product line, this furnace is designed for residential heating applications where reliable, mid-efficiency performance is required. A 9-speed constant torque blower motor delivers up to 2,000 CFM and adapts automatically between heating and cooling airflow demands. The integrated furnace control board features a digital status display, last-six-error memory, and all Molex connections for straightforward diagnostics and service. Licensed HVAC technicians install and commission this unit.

The A801X080CM5SC is a multi-position furnace approved for upflow, downflow, horizontal left, and horizontal right installations, making it well suited for a range of residential applications including basements, closets, attics, and crawlspace platforms. The cabinet width is 21 inches, an industry-standard dimension that simplifies coil and accessory pairing. The open vestibule design provides a full 34 inches of clearance for ease of installation and service access. The cabinet meets ASHRAE 193 air-tightness requirements at 1.4% or less air leakage, reducing uncontrolled airflow losses in the distribution system.
