Gas Duct Furnaces
Common in large commercial and industrial spaces with a central blower, gas duct furnaces are versatile, with models for both indoor and outdoor use. With gravity vented, power vented, and separated combustion designs using natural gas or propane, you'll be able to find a gas-fired duct furnace that works for you. Gravity-vented units are available in a variety of sizes, and designed to be used in your building's heating/cooling system with a natural draft. Power vented units may be a better choice for horizontal vent systems or when there's negative pressure around the unit.
Our experienced customer service team is prepared to help you choose the one that's right for your application. Browse our selection of gas duct furnaces, all of which qualify for fast, free shipping in the lower 48 states.
