Fuel Efficient Design
The S9X2 is rated at 96% gas efficiency (AFUE), and the Vortica™ II blower is one of the most efficient in the industry, providing energy savings in both winter AND summer.

Comfortable, even heating
With stainless steel primary and secondary heat exchangers, and the ultra-efficient Vortica™ II variable speed blower, you can count on a consistent flow of warm, comfortable air with quiet operation.

Get the best of both worlds with a hybrid system
Pair your gas furnace with a heat pump to enjoy the benefits of a hybrid system. Your heat pump primarily heats your home and your furnace steps in when the weather gets too cold. Together, they offer you reliable comfort that could lower your energy costs.
