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 GDH8 two-stage, multi-speed furnace utilizes Goodman's superior heat exchanger design to provide efficient, reliable heating to your home. This furnace also excels at providing comfortable circulation in a variety of conditions thanks to its four-speed blower motor. Designed for ease of installation, the GDH8 furnace has multiple options for gas, electrical, and return air connections. Maintenance is just as easy thanks to the unit's self-diagnosing control board. Backed by Goodman's generous warranty, the GDH8 provides comfort and peace of mind to homeowners.
Advanced Heat Exchanger Design
The GDH8 furnace employs a reliable dual-diameter tubular heat exchanger design. Aluminized steel is used in construction for incredibly efficient heat transfer, and a wrinkle-bend is applied to the tubes to enhance the heat exchanger's dependability and longevity.
Dual$aver Technology allows GDH8 furnaces to begin operating at the lower stage for ideal efficiency. The control board of the furnace then uses historical data about the rate of temperature change in your home to make an intelligent decision about whether the higher stage of heating will be necessary.
Goodman takes great pride in producing equipment that doesn't disrupt your home. The blower, motor, and gas valve of the GDH80804BX were selected for their incredibly low sound levels.
All GDH8 furnaces are protected by a durable steel cabinet with a long-lasting powder paint finish. The heat exchanger section of the cabinet is lined with foil-insulation to prevent heat loss.
The GDH80804BX 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.
