Trane A952V120DD5SA Two Stage Variable Speed Gas Furnace 120000 Btu/h 96% Afue Downflow

Product Description

The Trane A952V120DD5SA is a two-stage, variable-speed natural gas furnace rated at 120,000 BTU/h input capacity and 96% AFUE. It is part of the RunTru by Trane RT Series and is designed for downflow applications. The variable-speed ECM blower motor adjusts airflow to match heating demand, improving comfort and reducing energy consumption compared to single-speed units. The two-stage gas valve allows the furnace to run at a lower firing rate during mild conditions, reducing short-cycling and temperature swings. Licensed HVAC technicians install this unit as a primary heating source in ducted forced-air systems.

The A952V120DD5SA is designed for residential downflow installations where the supply air discharges through the bottom of the unit. With a cabinet width of 24.5 inches, it fits standard residential platform or utility room installations. The 24-volt control interface allows integration with standard thermostats and communicating controls. This furnace targets residential applications in climates requiring high heating output, and it is suitable for pairing with a central air conditioning coil in a split system configuration.

Compatibility

Designed for downflow ducted forced-air systems in residential applications. Cabinet width of 24.5 inches and downflow configuration must be confirmed against the installation site before ordering. Consult the unit's installation manual for approved coil and air handler pairings.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with the International Fuel Gas Code (IFGC) and all applicable local codes. Shut off gas supply and disconnect electrical power before beginning any service work. The downflow orientation requires a properly rated floor opening or plenum platform — verify clearances per the manufacturer's installation data sheet before mounting. Never operate the unit without all panels secured and the flue venting fully connected and inspected.
