    Overview for Goodman GMH80403AXUnlike conventional, single-stage furnace technology, Goodman's Dual$aver technology eliminates the temperature swings resulting from abrupt, high-stage stops and starts of the furnace by operating at a low heating state the majority of the time. This gas furnace has an AFUE rating of 80%, which means that 80 cents of every $1.00 of heating energy expense warms your home. The Goodman GME8 Two Stage, Multi-speed, Multi-position ECM Motor Series GMH80403AX Gas Furnace Heaters. The Goodman brand is one of the biggest names in home cooling, heating and energy-efficient home comfort. That
  • Advanced Heat Exchanger Design
  • The GMH8 furnace employs a reliable dual-diameter tubular heat exchanger design. Aluminized steel is used for incredibly efficient heat transfer, and a wrinkle-bend is applied to the tubes to enhance the heat exchanger's dependability and longevity.
  • Dual$aver Technology
  • Dual$aver Technology allows GMH8 furnaces to begin operating at the lower stage for ideal efficiency. The control board uses historical data about the rate of temperature change in your home to decide whether the higher stage of heating is necessary.
  • Quiet Comfort
  • The blower, motor, and gas valve of the GMH80403AX were selected for their incredibly low sound levels.
  • Secure Cabinet
  • All GMH8 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.
  • Easy Integration
  • The GMH80403AX 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.
  • Extended Warranty
  • Goodman offers a 10-year limited unit replacement and parts warranty when you register your product online within 60 days of installation. An unregistered product has the standard 5-year warranty. See the "Manuals" tab for more information.

Good product, fast shipping
By Peter W. 
Viroqua, Wisconsin
Purchased 09/24/2018 | 
Review Posted 10/17/2018 
Goodman has come quite a long way in quality and dependability over the past 10 years or so. This is the 4th Goodman system I have installed in as many houses. All function well, and are still in service.
They are easy to install by the experienced DIY guy. If you get stuck, there are lots of videos on you tube.
eComfort had the best price when you consider shipping costs. They included Free shipping, and Free lift gate service. Unit arrived undamaged in a couple days.
I would definitely purchase another Goodman, and I will continue to use eComfort.

Good Unit
By Kesse H. 
Westminster, California
Purchased 01/16/2018 | 
Review Posted 02/12/2018 
Great support from eComfort. Quick delivery too. Their website seems to provide all the manuals Goodman has to offer for the model (GMH81205DX) I ordered so you do not have to chase all over the internet to find the ones you want.
Goodman furnace design/layout is good it provides easy access to most components if any future repair and trouble-shooting were needed. Good documentations from Goodman too.

I was replacing a 40-year old, 125,000 BTU Payne 80% eff furnace. So I ordered a similar BTU Goodman furnace (120,000 BTU in and 96,000 BTU out) that proved to be more than necessary. The motor is 3/4 hp vs.1/2 hp so mine may be a little noisier.
The only other minor negative is that the two front panels are held by 3 screws into the thin sheet metal cabinet. I suspect it would not last too many on/offs without having to use bigger screws later so I think would be far better if Goodman uses knobs into threaded inserts like what I saw on a few other brands. It will also give the user a quality impression right away....
