QUICK FACTS

• This furnace is ideal to heat a smaller house (depending on climate)
• 40,000 BTU 96% AFUE natural gas furnace
• Requires plastic/PVC flue venting
• Can be used in the upflow or horizontal orientation
• Can be converted to an LP furnace with an optional conversion kit (sold separately)
• Innovative design for electrical efficiency, safety, and lower sound output

40,000 BTU

Heating up to a smaller house in normal conditions, the GMEC960403AN Goodman gas furnace has an input of 40,000 BTU™s and an output of 38,400 BTU™s. The output in this case is determined by taking the input times the efficiency rating.

96% AFUE

The GM9C960403AN Goodman gas furnace is a 96% efficient furnace, making it a condensing setup. This efficiency means that only 4% of the fuel going into the furnace is used up in furnace operations, while 96% of the fuel is used to heat your home. As a condensing furnace, this furnace will need to be vented with plastic or PVC flue venting. If you need to use metal flue venting, you would need an 80% efficient furnace.

Two Stage 9-Speed Furnace

With a two stage burner, the GM9C960403AN provides two heating outputs: one at a 60% heating output and one at a 100% output. The furnace also has a 9 speed ECM motor instead of the last-generation inefficient PSC motor. Both of these built-in upgrades allow for your furnace to adjust the heating output and airflow more precisely to better suit your home™s comfort needs and provide a slightly higher efficiency.

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.

Durability and Reliability

The exterior casing on the GM9C960403AN is heavy-gauge steel that is insulated for enhanced protection and to lower air leakage and sound output from normal furnace operation. The hot surface ignitor is more efficient than earlier models and standing pilot lights thanks to its revolutionary new technology. Both of these end up saving you money on installation, maintenance, and bills.

Installation and Maintenance

The cost-saving benefits of the Goodman brand doesn™t stop at efficiency. The GM9C960403AN Goodman furnace can be upflow or horizontal, increasing the number of ways that your installer can install the system. The low-voltage terminals that are color-coded, the installation is faster and easier over standard non-colored systems. Straight from the factory, the GM9C960403AN comes with natural gas valves. However, increasing its versatility in installation, Goodman offers an LP conversion kit (found here at an additional cost) if you need it to be propane instead of natural gas. Not only does the Goodman brand save you money on installation costs, but also with maintenance and warranty work. In the event of a rare warranty issue, the on board self-diagnostic control board alerts you and your serviceman what is wrong with the unit for most basic issues for a faster solution.

Please note that this furnace requires a drain kit if installed horizontally. Upflow configurations do not require the kit.
