    Goodman established itself as the largest HVAC manufacturer in the US by producing high-quality, efficient equipment and providing it to homeowners at a great value. The GDH8 two-stage, multi-speed furnace utilizes Goodman's superior heat exchanger design to provide efficient, reliable heating to your home. This furnace also excels at providing comfortable circulation in a variety of conditions thanks to its four-speed blower motor. Designed for ease of installation, the GDH8 furnace has multiple options for gas, electrical, and return air connections. Maintenance is just as easy thanks to the unit's self-diagnosing control board. Backed by Goodman's generous warranty, the GDH8 provides comfort and peace of mind to homeowners.
  • Advanced Heat Exchanger Design
  • The GDH8 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 GDH8 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 GDH81005CN were selected for their incredibly low sound levels.
  • Secure Cabinet
  • All GDH8 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 GDH81005CN 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.

New furnace install
By Chris W 
Dale City, Virginia
Purchased 07/28/2018 | 
Review Posted 10/02/2018 
The furnace was easy to install, I'm a electrician by trade and although I have never actually installed a furnace, this one was as simple as unhooking the old one and putting the new one right back in its place with no duct work at all . So far the furnace and A/C have both been working fine.

Review Posted 03/30/2018 
This unit is a tight air exchanger. Everything’s works as should. Quieter than the Heil I replaced. I wish the 2 front panels had better attaching screws with threaded inserts. Time will tell.

This furnace replaced the last one which was way too big for the small home I have. Fairly easy install although I did hire a pro to
do it.

After 55 years with an old furnace, this is it !!!
By Beatrice B. 
Venice, California
Purchased 11/06/2017 | 
Review Posted 12/11/2017 
I am very happy with my new furnace. It has made lots of differences in our home since the temperature had gone very low in the mornings and evenings. Our old unit was over 55 years, but now we see overall the difference and specifically the efficiency of the new unit.
It's too early to tell about other qualities since we placed it in service about 5 days ago. So far, so good.
