Trane A952V100CD5SA Two Stage Variable Speed Gas Furnace 100000 Btu 96 Percent Afue Dedicated Downflow 21 Inches Wide

Product Description

The Trane A952V100CD5SA is a two-stage, variable-speed condensing gas furnace engineered for dedicated downflow installations. Rated at 100,000 BTU input capacity with a 96 percent AFUE efficiency rating, this unit delivers approximately 96,000 BTU of usable heat output per operating cycle. The variable-speed ECM blower motor modulates airflow to match heating demand, reducing temperature swings and operating noise compared to single-speed units. Two-stage gas valve operation allows the furnace to run at a reduced firing rate during mild conditions, improving comfort and fuel efficiency. It operates on 120 volt, single-phase, 60 Hz power with 24-volt low-voltage control wiring. Licensed HVAC technicians handle installation and commissioning of this equipment.

The A952V100CD5SA is designed for residential downflow applications where the supply air discharges through the bottom of the unit into a floor-level plenum or crawlspace duct system. Its dedicated downflow configuration makes it well suited for homes with basement-free layouts or installations over conditioned crawlspaces. The 21-inch width cabinet and 28.75-inch depth allow it to fit standard residential alcove or closet installations. This unit has been paired in system configurations with Trane and RunTru by Trane air conditioner and heat pump components, including the A4AC3048D1 and A4AC4042D1 outdoor units with compatible air handlers.

Key Features

• 96 percent AFUE two-stage condensing operation reduces fuel consumption during partial-load conditions
• Variable-speed ECM blower delivers precise airflow control and quieter operation versus single-speed alternatives
• Dedicated downflow cabinet orientation for floor-discharge duct systems
• 24-volt low-voltage control interface compatible with standard residential thermostats
• 120/1/60 electrical supply — standard residential single-phase power
• 21-inch wide cabinet fits common residential closet and alcove furnace spaces

Compatibility

The A952V100CD5SA has been used in system configurations with the A4AC3048D1 and A4AC4042D1 outdoor units paired with compatible Trane and RunTru by Trane air handler coil assemblies in downflow arrangements. Verify coil, thermostat, and venting compatibility with current Trane engineering documentation before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with the current edition of the IFGC, NFPA 54, and all applicable local codes. Shut off gas supply and disconnect electrical power before servicing or connecting the unit. This is a condensing furnace requiring a dedicated direct-vent flue system — do not connect to a B-vent or common-vent chimney. Verify that the downflow duct system, supply plenum, and floor opening are sized to the unit's airflow requirements before startup.
