General Electric nf96d090s4c Downflow Gas Furnace 96% Afue

Product Description

The GENERAL ELECTRIC nf96d090s4c is a single-stage downflow gas furnace rated at 90,000 BTU/h with a 96% Annual Fuel Utilization Efficiency (AFUE) rating. Designed for residential forced-air heating systems, this unit delivers consistent heat output through a downflow configuration, meaning conditioned air is discharged from the bottom of the cabinet. At 96% AFUE, nearly all the fuel consumed is converted to usable heat, minimizing waste and reducing operating costs over the life of the system. Licensed HVAC technicians install and commission this furnace as part of a complete ducted heating or heating and cooling system.

This furnace is suited for residential applications where the air handler or furnace must discharge downward into a subfloor duct system or a dedicated plenum beneath the unit. A downflow configuration is common in installations where the ductwork runs beneath the floor, such as homes built on a crawl space or slab. The 4-ton cooling compatibility rating indicates this furnace cabinet and coil section are sized to work alongside a matched 4-ton cooling coil in a split or packaged system configuration. Single-stage operation means the gas valve and burner operate at full capacity whenever the thermostat calls for heat.

Key Features

• 90,000 BTU/h heating capacity for residential forced-air systems
• 96% AFUE rating for high-efficiency fuel utilization
• Single-stage operation with consistent full-capacity heat output
• Downflow discharge configuration for subfloor duct installations
• Sized for use with a 4-ton cooling coil in a split system

Compatibility

Designed as an OEM-style downflow gas furnace for residential forced-air heating systems requiring a high-efficiency single-stage unit with a downflow discharge orientation.

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 instructions. Shut off the gas supply and disconnect electrical power before servicing or connecting any components. Proper flue venting, gas line sizing, and combustion air provisions must be verified before startup. A licensed professional should conduct a full system startup, including gas pressure verification and airflow commissioning, before the system is placed in service.
