Trane A952V100CU5SA Two Stage Condensing Gas Furnace 100000 Btu Upflow Horizontal Variable Speed 96 Percent Afue 21 Inch Cabinet

Product Description

The Trane A952V100CU5SA is a two-stage, variable-speed condensing gas furnace rated at 100,000 BTUH input capacity and 96% AFUE. It is designed for upflow installations and is field-convertible to horizontal left or horizontal right airflow configurations. The unit uses a 21-inch wide cabinet and delivers a nominal 2,000 CFM of airflow via an ECM variable-speed blower motor. Control is handled through a 24-volt low-voltage interface with an integrated furnace control board that includes a digital display, last-six-error storage, and diagnostic capability. Licensed HVAC technicians typically handle installation and commissioning of this unit.

The A952V100CU5SA is suited for residential forced-air heating applications where a high-efficiency, multi-position gas furnace is required. The upflow orientation makes it a common fit for basement and utility-room installations, while the convertible horizontal configuration expands placement flexibility in crawlspace or attic settings. The cabinet width of 21 inches is an industry-standard dimension, allowing compatibility with standard evaporator coils and accessories in split-system or dual-fuel heat pump configurations. It has been referenced as a component in 3.5-ton, 15.2 SEER2 dual-fuel systems paired with matching outdoor heat pump and coil components.

Key Features

• 96% AFUE two-stage condensing operation reduces fuel consumption compared to single-stage furnaces
• Variable-speed ECM blower motor supports nominal 2,000 CFM with airflow setup options down to 290 CFM per ton
• Convertible to upflow, horizontal right, or horizontal left orientation without a separate kit
• Integrated furnace control board with digital display, setup and diagnostics, and last-six-error memory — no dip switches required
• Air-tight cabinet with 1.4% or less air leakage per ASHRAE 193
• Open vestibule design provides 34 inches of vertical access height for service and component access

Compatibility

The A952V100CU5SA has been documented as a component in a 3.5-ton, 15.2 SEER2, 96% AFUE upflow gas furnace and heat pump system alongside outdoor unit A4HP5042D1 and indoor coil 4MXCC009AC6HCB. The 21-inch cabinet width is an industry-standard dimension designed to accept standard evaporator coils and accessories.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with the International Fuel Gas Code (IFGC), local mechanical codes, and the manufacturer installation, operation, and maintenance documentation. Shut off gas supply and disconnect electrical power at the breaker before beginning any service or installation work. Vent connections must comply with applicable Category IV venting requirements for condensing appliances, and condensate drainage must be properly routed and trapped per local plumbing code.
