Goodman GMS 80% Efficient Multi-Speed Gas Furnace
The Goodman® GMS8 80% AFUE Multi-Speed Gas Furnace, provides effective home heating at an affordable price. Energy efficiency is key to controlling the cost of heating your home. This furnace’s 80% AFUE rating means 80 cents of every $1.00 of heating energy expense warms your home. Some older central heating systems rate at 60% AFUE, meaning only 60 cents of the gas burned contributes to your home’s heating. The remaining 40 cents is lost energy – wasteful and expensive. Switching to a Goodman 80% furnace cuts that loss in half.

The Goodman GMS8 Furnace uses a multispeed blower motor and sound-isolated blower assembly to reduce the noise levels common in other furnaces. Add an insulated, heavy-gauge steel cabinet, and the result is…extra-quiet comfort.
The heart of any furnace is the heat exchanger. The TuffTube™ aluminized-steel tubular heat exchanger and stainless-steel recuperative coil used in this furnace, have been tested to the highest industry standards.
For further safety and reliability, the furnace utilizes an energy-saving Hot Surface Ignition system, featuring a Norton Mini-Igniter and a patented Adaptive Learning Routine that helps insure safe start-ups and maximum igniter life.Additionally, the Goodman GMS8 Furnace is designed to minimize NOx emissions, contributing to better air quality inside and outside of your home.
