Trane A952V080BD4SB Gas Furnace 80000 Btu 96% Afue Variable Speed Two Stage Downflow 17.5 Inches

Product Description

The Trane A952V080BD4SB is a two-stage, variable-speed natural gas furnace rated at 80,000 BTU input and 96% AFUE. It is engineered for downflow installation and carries the RunTru by Trane designation, placing it in Trane's value-tier residential lineup. The variable-speed blower motor modulates airflow to match heating demand, which reduces temperature swings and lowers operating noise compared to single-speed units. Two-stage gas valve operation allows the furnace to run at a lower firing rate during mild weather, improving comfort and efficiency. Licensed HVAC technicians handle installation and commissioning of this unit.

The A952V080BD4SB is designed for residential downflow applications where supply air is discharged downward into the duct system, a configuration commonly required in homes with crawl-space or slab ductwork. At 17.5 inches wide, the cabinet fits standard residential furnace alcoves sized for mid-width equipment. The 96% AFUE rating makes it compliant with northern-region minimum efficiency standards in the United States, and the unit is fueled by natural gas. It is suited for replacement installs or new construction where a downflow, high-efficiency gas furnace is specified.

Compatibility

Designed as an OEM-style downflow residential gas furnace. The A952V080BD4SB has been listed as a component in 3.5-ton, 14.3 SEER2 matched system configurations. Verify system compatibility with Trane engineering literature and local code requirements before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with the National Fuel Gas Code (NFPA 54 / ANSI Z223.1) and all applicable local codes. Shut off gas supply and disconnect electrical power at the disconnect box before servicing or connecting the unit. Downflow furnaces require a properly sized supply plenum and a non-combustible floor base when installed on combustible flooring. Do not fire the furnace until venting, gas piping, and electrical connections have been inspected and verified by a qualified technician.
