Goodman 96% AFUE 40k BTU Two-Stage Gas Furnace GC9C960403BN

Benefits of the Goodman 96% AFUE 40k BTU Two-Stage Gas Furnace GC9C960403BN

The Goodman brand consistently brings efficiency and other cost-saving benefits and technology to their furnace. The GC9C960403BN gas furnace is no exception to Goodman’s ingenuity in design, bringing you comfort at high efficiency for any downflow or horizontal application.

Features of Goodman 96% AFUE 40k BTU Two-Stage Gas Furnace

  • This furnace is ideal to heat a smaller house (depending on the climate)
  • 40,000 BTU 96% AFUE natural gas furnace
  • Requires plastic/PVC flue venting
  • Can be used in the downflow 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

Heating up to a smaller house in average environmental conditions, the GC9C960403BN Goodman furnace has an input of 40,000 BTUs and an output of 38,400 BTUs (input X efficiency rating = output).

The GC9C960403BN gas furnace is 96% efficient. This efficiency means that 4% of the fuel going into the furnace is lost out of the flue venting, 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 are looking for a furnace that requires metal flue venting, you would need an 80% efficient furnace.

With a two-stage burner, the GC9C960403BN provides two heating outputs: one at a 60% heating output for warmer days and one at a 100% output for when you need the furnace most. The furnace also has a 9-speed ECM motor instead of an inefficient PSC motor. Both of these upgrades provide better efficiency with a more stable output to better heat your home through all seasons of use.

With an installation that follows your state and local codes, the GC9C960403BN gas furnace comes with a 10-year parts and lifetime heat exchanger warranty when registered online through Goodman.

The outer casing on the GC9C960403BN gas furnace is heavy-gauge steel with enhanced insulation for better protection and lower air leakage and sound output, providing more comfort to your home. The new hot surface ignitor replaces the standing pilot light for a more efficient startup.

The cost-saving benefits of the Goodman brand don’t stop at efficiency. The GC9C960403BN Goodman furnace can be installed in either the downflow or horizontal orientation, making this furnace an ideal choice for multiple installation applications. Naturally, the GC9C960403BN comes with natural gas valves built-in. However, increasing its installation potential, the GCEC960403BN can be field converted with the LP conversion kit (found here, for an extra fee) if you need it to be propane. 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 self-diagnostic control board alerts you and your serviceman what is wrong with the unit for most basic issues for a faster solution to almost any problem.
