The GMSS92 single-stage, multi-speed furnace uses a pair of steel heat exchangers to convert 92% of the energy used into comfort. It is equipped with a four-speed blower motor, which provides your home with comfortable circulation through a wide variety of conditions. The GMSS921005CN was designed with multiple options for the unit's gas, electric, and venting connections and orientation, ensuring a painless and quick installation. It even features a self-diagnosing control board that makes maintenance a breeze. If you're looking for reliable comfort and excellent energy efficiency from a single-stage furnace, it's tough to beat Goodman's GMSS92.

Advanced Heat Exchanger Design

  • The GMSS92 furnace employs a reliable dual-diameter tubular heat exchanger design. Aluminized steel is used for incredibly efficient heat transfer, and a wrinkle-bend is applied to the tubes to enhance the heat exchanger's dependability and longevity.

Secondary Heat Exchanger

  • This furnace produces addition heat by directing combustion gases through a secondary heat exchanger before they are vented. The secondary heat exchanger is made of corrosion-resistant stainless steel and it is sloped to prevent condensate build-up.

Quiet Comfort

  • The blower and gas valve of the GMSS921005CN were selected for their incredibly low sound levels.

Venting Options

  • The GMSS921005CN offers several venting options to streamline installation in a variety of applications. It can be used in either a two-pipe direct vent setup or a single-pipe configuration with combustion air.

Secure Cabinet

  • All GMSS92 furnaces are protected by a durable steel cabinet rated for less than 2% air leakage. The heat exchanger section is lined with foil-insulation to prevent heat loss and the return side of the cabinet is solid and airtight.

Extended Warranty

  • Goodman offers a 10-year limited parts warranty when you register your product online within 60 days of installation. An unregistered product has the standard 5-year warranty. See warranty sheet under the "Manuals" tab for more information.
