Trane A952V080CU5SB Variable Speed Two Stage Gas Furnace 80000 Btu/h 96% Afue Upflow

Product Description

The Trane A952V080CU5SB is a condensing natural gas furnace in the RunTru by Trane RT Series, rated at 80,000 BTU/h input and 96% AFUE efficiency. The unit delivers approximately 76,000 BTU/h of usable heat output, making efficient use of fuel across the heating season. A variable speed ECM blower motor and two-stage gas valve work together to modulate heating output and airflow, reducing short-cycling and improving comfort distribution. The cabinet is 21 inches wide and is designed for upflow or horizontal installation. Licensed HVAC technicians install and commission this unit in residential forced-air heating systems.

The A952V080CU5SB is suited for residential upflow or horizontal duct configurations where high-efficiency condensing operation is required. The 96% AFUE rating places it in the condensing category, requiring a PVC flue and condensate drain line as part of the installation. This furnace pairs with a central air conditioning system and indoor coil in a split-system configuration. It is appropriate for homes in cold and mixed climates where high seasonal efficiency directly reduces operating costs. System sizing should follow Manual J load calculations to confirm the 80,000 BTU/h input is appropriate for the structure.

Key Features

• 80,000 BTU/h input with approximately 76,000 BTU/h heat output at 96% AFUE
• Two-stage gas valve reduces output at partial load for improved comfort and efficiency
• Variable speed ECM blower motor modulates airflow to match heating and cooling demand
• Condensing design achieves 96% AFUE, qualifying as a high-efficiency unit under current federal minimums in northern climate regions
• 21-inch cabinet width accommodates standard residential equipment closets and utility rooms
• Upflow and horizontal airflow configurations supported from a single cabinet

Compatibility

Designed for use in split-system residential HVAC configurations as the air handler and heating source. Compatible with matched RunTru by Trane condensing coils and outdoor condensing units; consult Trane system matching guides to confirm coil and condenser compatibility before ordering.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with the National Fuel Gas Code (NFPA 54), local mechanical codes, and the manufacturer installation, operation, and maintenance manual. Shut off gas supply and disconnect electrical power at the disconnect switch before any service work. This is a condensing furnace and requires a dedicated PVC vent system and a gravity or pumped condensate drain line routed to an approved drain. Do not reuse existing B-vent or single-wall metal flue pipe with this unit.
