Product Description

The Trane A951X100CD5SA is a dedicated downflow, single-stage condensing gas furnace rated at 100,000 BTU/h input with a 95% AFUE efficiency rating. It uses an ECM blower motor with multiple speed settings to deliver consistent airflow while reducing energy consumption during blower operation. This furnace is designed for residential heating applications and is compatible with both natural gas and propane. Licensed HVAC technicians install and commission this unit as part of a forced-air heating system or matched split system. The ENERGY STAR certification confirms the unit meets federal efficiency criteria for condensing gas furnaces.

The A951X100CD5SA is engineered for downflow-only installations, meaning the supply air discharges from the bottom of the cabinet. This configuration is common in homes where the ductwork runs beneath the unit, such as installations in closets over a crawl space or on a main floor above a basement supply plenum. The unit belongs to the RunTru by Trane A951X furnace family and carries an ENERGY STAR certification dated for market availability beginning July 2019. It is suited for residential single-phase electrical service.
