Ge NF97D070V4BR 70000 Btu 97% Afue Two-stage Gas Furnace

Product Description

The GENERAL ELECTRIC NF97D070V4BR is a two-stage downflow gas furnace rated at 70,000 BTU/h with a 97% AFUE efficiency rating. It is designed for residential forced-air heating systems where the air handler or coil cabinet is positioned below the furnace in a downflow configuration. The unit supports R454B refrigerant and is rated for up to 4 tons of cooling capacity when paired with a compatible air conditioning or heat pump system. Two-stage operation allows the furnace to run at a lower firing rate during mild conditions, reducing short-cycling and improving comfort. Licensed HVAC technicians perform installation and commissioning.

This furnace is suited for residential applications requiring high-efficiency gas heat in a downflow cabinet orientation. Downflow installations are common in homes where ductwork runs beneath the living space, such as slab-on-grade construction or installations over a crawl space. The 97% AFUE rating qualifies this unit for energy efficiency programs in many jurisdictions. The 4-ton refrigerant circuit compatibility makes it appropriate for matched split systems using R454B refrigerant. Two-stage firing supports better humidity control and more even temperature distribution compared to single-stage units.
