Goodman established itself as the largest HVAC manufacturer in the US by producing high-quality, efficient equipment and providing it to homeowners at a great value. The GCSS96 multi-speed furnace uses a pair of steel heat exchangers to convert 96% of the energy used into comfort, Goodman's highest mark for a single-stage furnace. It is equipped with a four-speed blower motor, which provides your home with comfortable circulation through a wide variety of conditions. The GCSS960402BN 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. When it comes to high efficiency heating from a single stage furnace, Goodman's GCSS96 sets the standard..

Advanced Heat Exchanger Design
The GCSS96 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 GCSS960402BN were selected for their incredibly low sound levels. Additionally, this unit offers an airflow system and fan speed options that allow it to operate quietly while providing consistent comfort.

Venting Options
The GCSS960402BN 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 GCSS96 furnaces are protected by a durable steel cabinet rated for less than 2% air leakage. The heat exchanger section is insulated to prevent heat loss and the return side of the cabinet is solid and airtight.

Goodman's Auto-Comfort mode is available in applications where the GCSS960402BN is used to distribute cooled air. This mode scales output up to the cooling demand in stages for improved comfort, efficiency, and dehumidification.

Easy Integration
The GCSS960402BN makes it simple to enhance your system with a humidifier and an electronic air cleaner; just wire them directly to the low-voltage terminals on the control board.

Extended Warranty
Goodman offers a 10-year limited unit replacement and parts warranty when you register your product online within 60 days of installation. An unregistered product has the standard 5-year warranty.
