Product Description
The Trane A952V100CU5SB is a 2-stage, variable speed, condensing natural gas furnace rated at 100,000 BTU input and 96% AFUE. It is part of the RunTru by Trane RT Series and is designed for upflow, horizontal left, and horizontal right installations. The variable speed ECM blower motor adjusts airflow continuously to maintain consistent temperatures and reduce energy consumption at the air distribution level. Nominal airflow capacity is 2,000 CFM. The 24-volt control system is compatible with standard thermostat wiring. Licensed HVAC technicians install this unit in residential forced-air heating systems.
The A952V100CU5SB is suited for residential applications where a high-efficiency, multi-stage gas furnace is required. Its upflow and horizontal orientation flexibility makes it a practical fit for basement, closet, utility room, and attic installations. The 2-stage burner allows the furnace to run at a reduced capacity during milder outdoor conditions, reducing short-cycling and improving comfort consistency. The 21-inch wide cabinet fits standard residential equipment spaces. This unit is intended for direct-vent or non-direct-vent configurations depending on the installation design.
