What does 96% AFUE mean?

It means 96% of the gas burned becomes usable heat, with the rest lost mainly through the flue. That puts it in the condensing, high-efficiency class.

Does it need special venting?

Yes. As a condensing furnace it vents through PVC pipe, usually out a side wall, and needs a condensate drain. It cannot use a standard metal flue.

What is the difference between two-stage and single-stage?

Two-stage runs at a lower output most of the time and steps to full output only when needed. That gives longer, gentler cycles and quieter operation than a single-stage furnace.

What size home is 80,000 BTU for?

It typically suits homes in the roughly 2,000 to 2,800 square foot range in moderate climates, less in very cold regions. A load calculation from your contractor is the reliable way to size it.

Can I add a humidifier or air cleaner?

Yes. The cabinet is set up to accept electronic air cleaners and humidifiers.

Can I install it myself?

No. Gas piping, venting, electrical and combustion air all require a licensed HVAC contractor and usually a permit.

About the Goodman 80,000 BTU Gas Furnace 96% AFUE Two-Stage

The Goodman GR9T960803BN is an 80,000 BTU two-stage gas furnace with a 96% AFUE rating. It is built for upflow or horizontal installation and has a 17.5-inch-wide cabinet. The high efficiency means minimal energy waste, and the furnace qualifies for tax incentives due to its high energy efficiency.

The cabinet is heavy-gauge steel with a fully insulated heat exchanger and blower section. It supports upflow, horizontal, or side return air setups. Gas and electrical connections can be made on the left or right, and the furnace is certified for single-pipe or dual-pipe venting.

A self-diagnostic control board helps with troubleshooting. The furnace has a durable igniter and a condensate management design that drains faster to help prevent water leakage. It runs quietly and has low NOx emissions. It also integrates with electronic air cleaners and humidifiers.
