80,000 BTU 80% AFUE Single Stage Ultra-Low NOx Goodman Gas Furnace | 21" Width | Upflow / Horizontal
OVERVIEW
The GR9S800805CU Goodman gas furnace features high-quality construction and efficient operation at a great value. The GR9S800805CU single-stage, multi-speed furnace utilizes Goodman's superior heat exchanger design to provide efficient, reliable heating to your home. If you're looking to cut your energy bills and improve your comfort without breaking the bank, your search stops with the Goodman GR9S800805CU.
QUICK FACTS
- This furnace is ideal to heat a medium-sized house (depending on climate)
- 80,000 BTU 80% efficient natural gas furnace
- Requires metal flue venting
- Can be used in the upflow or horizontal orientation
- Ultra-Low NOx Compliant for California
- Innovative design for electrical efficiency, safety, and lower sound output
80,000 BTU
The GR9S800805CU Goodman gas furnace is 80,000 BTU’s. This BTU count is a measure of the input of the furnace per hour, while the output of this furnace is 64,000 BTU’s (80,000 X 80% AFUE) per hour. In ideal climate conditions, this 80,000 BTU furnace is usually used to heat a small house.
80% Efficiency Rating
The GR9S800805CU Goodman gas furnace is 80% efficient, and the standard furnace efficiency on the market today. This means that 80% of the gas going into the furnace is used to heat your home and the remaining 20% is lost out of the flue venting. Please note that all 80% furnaces must be vented using metal flue venting, while anything higher than 90% efficient must be vented using plastic/pvc venting.
Single Stage Furnace
The GR9S800805CU Goodman gas furnace is a single stage furnace has only one heat output. Regardless of the indoor temperature, this furnace will burn at 100% output whenever the thermostat calls for it. Like a light switch, this furnace’s burner will either be on or off and nothing in between. A single stage furnace is the standard efficient furnace since every time your furnace turns on the furnace uses the same amount of energy.
Multi-Speed ECM Blower Motor
Instead of the last generation PSC blower motor, the GR9S800805CU utilizes a 9-speed ECM motor, which uses less power and provides smarter air circulation. All of this causes an overall increase in the electrical efficiency of your furnace, which saves you money.
Warranty
With installation that follows your state and local codes and with online registration, all Goodman furnaces come with a 10-year parts and lifetime heat exchanger warranty through the manufacturer.
Durable Hot Surface Igniter
The hot surface igniter on modern Goodman furnaces are more durable than previous designs, decreasing related issues and lowering maintenance costs. These hot surface ignitors are also more efficient than standing pilot and older HSI designs, saving you even more money.
Self-Diagnostic Control Board
The Goodman brand has improved technology from years of production experience, allowing for a long-lasting product that rarely has any issues. However, if something does go wrong on the furnace, the control board has a set of sensors that allow it to diagnose basic issues, allowing for easy troubleshooting and to notify the owner if basic maintenance or warranty work is recommended. This increases the overall safety of the unit, for the furnace itself and the occupants of the home where it is installed.
Heavy Gauge Steel Cabinet
The heavy-gauge steel cabinet on new Goodman furnaces provide adequate protection to the internal mechanisms of the unit. The cabinet is also more air-tight than previous models, allowing for a quiet, more economical unit due to losing less heat and preventing more sound from exiting the unit.
Ease of Installation
The value of modern Goodman furnaces doesn't end at efficiency. Today’s Goodman furnaces feature many different connection options to reduce installation. The GR9S800805CU model has a more universal design, which consists of its ability to be installed in both an upflow or horizontal configuration. This allows for an easier installation in more locations, from your attic to your basement. The furnace also comes with color-coded low-voltage terminals that allow for a shorter and easier installation time, which decreases installation costs.
Customers Say
Across multiple purchases, buyers report fast shipping—often within days or even 27 hours—and straightforward installation, with models like the Goodman 80% AFUE units in 60k, 80k, and 120,000 BTU sizes heating spaces up to 2,100 sq ft and a 1,320 sq ft home effectively and quietly. Owners cite replacements lasting 17 to 30 years, note easy DIY installs sometimes verified by licensed techs, and mention minor issues such as missing instructions, occasional shipping damage or wrong units, basic construction, and warranty requirements for certified troubleshooting.

- Great OptionI will say that HVAC direct provides a great service in not having to jump through hoops in order for a home owner to buy a furnace. The furnace is built pretty basic and that is what I wanted. Just keep in mind that if you are a homeowner installing the unit on your own and you have an issue with the furnace, you must have a certified tech troubleshoot and give you a report to forward to Goodman in order to use the warranty. HVAC direct ships fast as lightning. Don't be afraid, buy the equipment and save thousands.

- My experienceI only bought a lower end furnace; but that's not to say it's not a good furnace. For the cost I'm 'very' happy. I expect that as time goes on parts will never be an issue. Nothing fancy here, just a good basic gas furnace. I have experience so I installed it myself, which makes the experience super affordable. Shipment was lightning fast. I live within one state of their West Coast Distribution Center, so I had my furnace in 27 hours from order placement. I would highly recommend HVAV Direct. While I didn't need it, I understand from friends who have; they have great sales support too.
