Heating Capacity and Indoor Equipment Setup
This Furnace & Coil System is perfect for 600-1,000 sq. ft. homes in various climates when properly sized and installed. The system is built around a Goodman gas furnace and cased evaporator coil, with the coil selected for a compatible indoor equipment setup. Proper furnace sizing should always be confirmed through a professional load calculation based on home size, climate, insulation, windows, ceiling height, layout, air leakage, and other home-specific factors.
Efficient Everyday Furnace Performance
A 96% AFUE furnace provides high-efficiency gas heating designed to convert more of the fuel consumed into usable heat for your home. For example, a 40,000 BTU input rating at 96% AFUE provides approximately 38,400 BTUs of usable heating output, while a smaller portion is lost during the combustion process and exits through the venting. Because this is a 96% AFUE furnace, it uses plastic or PVC venting instead of the metal flue venting required for 80% AFUE furnaces.
Designed for Compatible Condenser Matching
The indoor coil works with a compatible condenser as part of a split HVAC setup. The system must be paired with a condenser using the same refrigerant type, and condenser tonnage cannot exceed the tonnage of the coil. If you are not sure whether this Furnace & Coil System will work with your condenser, please call us before purchasing.
Flush-Fit Coil for a Cleaner Indoor Setup
The included cased coil is selected to match the furnace cabinet width, creating a cleaner fit between the furnace and coil. For this system, the furnace and coil share a 17.5" cabinet width, helping support proper airflow alignment, installation fit, and a more streamlined indoor equipment setup.
Warranty
When installed according to applicable codes and registered online with Goodman, this Furnace & Coil System includes:
- 10-Year Parts Limited Warranty

40,000 BTU
The GR9S960403BU Goodman gas furnace is 40,000 BTU's, which is the smallest Goodman furnace size currently available. This BTU count is a measure of the input of the furnace per hour, while the output of this furnace is 38,400 BTU's (40,000 X 96% AFUE) per hour. In ideal climate conditions, this 40,000 BTU furnace is usually used to heat a small house.
96% Efficiency Rating
The GR9S960403BU Goodman gas furnace is 96% efficient, and the standard furnace efficiency on the market today. This means that 96% of the gas going into the furnace is used to heat your home and the remaining 4% is lost out of the flue venting. Please note that all 96% furnaces must be vented using plastic/PVC flue venting, while anything higher than 90% efficient must be vented using plastic/PVC venting.
Single Stage Furnace
The GR9S960403BU 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.
Natural Gas Furnace
From the factory, the GR9S960403BU, as well as other ultra-low NOx furnaces, runs on natural gas. These types of furnaces are only available in natural gas configurations. If you need a propane furnace, you will need to order a standard NOx furnace and add a propane conversion kit to it.
9-Speed ECM Blower Motor
Instead of the last generation PSC blower motor, the GR9S960403BU 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 GR9S960403BU 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.
Please note that this furnace requires a drain kit if installed horizontally. Upflow configurations do not require the kit.
Customers Say
Reviewers report effective heating, including a 120,000-BTU, 80%-efficiency furnace keeping a 2,100-square-foot house comfortable and another unit heating a 1,320-square-foot home.
