Built for properties with substantial heating needs, this high-efficiency furnace combines two-stage heat with a variable-speed blower. Its wide airflow range also supports larger cooling systems.
The Goodman GRVT961205DN gas furnace provides up to 120,000 BTU of heating input and approximately 115,320 BTU of high-stage output.
The Goodman 120000 BTU gas furnace uses a 24.5-inch D-width cabinet and supports upflow or horizontal positioning.
With a 96.1% efficiency rating, the Goodman 96 AFUE furnace converts most of the fuel it consumes into usable indoor heat.
Goodman GRVT961205DN Overview
The Goodman GRVT961205DN gas furnace operates at two heating levels. Its lower stage uses 84,000 BTU of input and produces approximately 80,724 BTU of output. Full capacity is available when the heating demand rises.
A Goodman variable-speed ECM furnace can adjust blower output in smaller steps than a fixed-speed unit. This produces a gentler stream of conditioned air and supports steadier temperatures from room to room.
The Goodman two-stage gas furnace normally starts at its lower heating level. Longer low-stage cycles can reduce abrupt temperature changes while keeping full heating output ready for colder conditions.
The Goodman 120000 BTU gas furnace can support cooling airflow for systems ranging from approximately 2 to 5 tons. Maximum selectable cooling airflow reaches about 2,200 CFM.
Key Features of Goodman 120K BTU Gas Furnace
The Goodman GRVT961205DN gas furnace pairs substantial heating capacity with ComfortBridge controls. The system manages communication and airflow from the furnace control board, so it can work with a compatible conventional thermostat.
