Nortek Global Hvac FG7SD-108D-T45D2 Gas Upflow Furnace 95 Afue Bargain

The NORTEK GLOBAL HVAC FG7SD-108D-T45D2 is a residential gas upflow furnace rated at 95 AFUE, designed for high-efficiency heating in forced-air systems. This premium-tier unit delivers condensing-class efficiency by extracting heat from combustion gases that standard furnaces exhaust, reducing fuel consumption and operating costs. The upflow configuration directs conditioned air upward through the supply plenum, making it the standard choice for basement, closet, and utility-room installations. Licensed HVAC technicians perform installation and commissioning on this equipment class.

This furnace is intended for residential forced-air heating applications. The upflow cabinet orientation suits installations where the air handler sits below the ductwork, feeding supply air into an overhead distribution system. At 95 AFUE, it meets or exceeds efficiency thresholds required in many regional energy codes, making it appropriate for both new construction and high-efficiency replacement projects in single-family and light multi-family residential settings.
