What's included

The Goodman GKS9 Series High-Efficiency Gas Furnace is a great system for homeowners who want a dependable heating system that operates both safely and energy efficiently. Sporting a heavy-duty tubular heat exchanger and hot-surface igniter, every GKS9 furnace is also built standard with a stainless-steel secondary heat exchanger, self-diagnostic control board, multi-speed blower motor, 10-Year Parts Limited Warranty, and a Lifetime Heat Exchanger Limited Warranty.

Whether your home is large or small, Goodman has a gas furnace to meet your unique needs! At 92% AFUE, the GKS90 is highly efficient and works hard to keep your monthly energy bills (and noise levels!) low.

Did you know that furnaces made in past decades often were only about 65% efficient? This is a huge upgrade from past models! The higher the efficiency number, the more heat the furnace can fuel from each therm of gas. With this efficiency, you will rest assured that your home will be warm and cozy!

This cabinet is 21” in size and a good fit for many homes. It’s important to know what size cabinet will best fit your home because a furnace that is too small will not keep your home properly warm. On the flip side, you don’t need to overspend for a furnace that is too large because bigger is not necessarily better.

The 90k BTU 92% AFUE Multi Speed Goodman Gas Furnace - Upflow - 21" Cabinet works hard to channel heat to your home with a top-of-the-line blower, igniter and motor. Unlike past furnace models, this furnace will channel exhaust through a stainless steel heat exchanger to pump additional heat, so you are wasting very little heat. With this gas furnace from Goodman, you are making a sound choice in heating your home!
