Trane A952V120DU5SB Gas Furnace 120000 Btu/h 96% Afue Two Stage Variable Speed Upflow Horizontal

Product Description

The Trane A952V120DU5SB is a two-stage, variable speed, condensing gas furnace rated at 120,000 BTU/h input and 96% AFUE. It is designed for residential heating applications in upflow or convertible horizontal installations. The variable speed ECM blower motor adjusts airflow continuously to match system demand, improving comfort and reducing energy use compared to single-speed alternatives. Two-stage heating allows the unit to run at a reduced first-stage capacity under moderate load conditions, reserving full second-stage output for the coldest days. Licensed HVAC technicians install and commission this furnace as part of a split or packaged residential system.

The A952V120DU5SB installs in upflow orientation and converts to horizontal left or horizontal right configurations, making it adaptable to a range of residential mechanical room and attic layouts. The 24.5-inch wide cabinet fits standard D-size furnace openings. It operates on 24-volt control wiring and delivers a nominal airflow of 2,000 CFM, suiting it for larger residential applications in the 2,000 to 3,000 square foot range. First-stage input capacity is 78,000 BTU/h, with full second-stage input at 120,000 BTU/h. The unit accepts both natural gas and propane fuel and carries ENERGY STAR certification.
