Our take on the Goodman GMVC801005CN Gas Furnace

The Goodman GMVC801005CN is an 80% AFUE gas furnace with a 100,000 BTU input and 80,000 BTU output. Its two-stage burner and variable-speed ECM blower run at lower output in mild weather and ramp up in deep cold, which smooths temperature swings and quiets operation. It fits upflow or horizontal installs and pairs with 2 to 5 tons of cooling. Against single-stage 80% furnaces it offers steadier comfort and quieter ramping; against 90%+ condensing models it gives up efficiency and needs a standard 4-inch vent rather than PVC. Owners of the GMVC line generally report reliable, comfortable heat, with the usual caveats about installer quality and parts availability.

  • ReliabilityPraisedMany owners report several seasons of service with no major breakdowns.
  • Repair costCriticisedWhen the control board or ECM blower fails, owners say the parts are expensive.

About the Goodman GMVC801005CN Gas Furnace

It has a two-stage gas burner and a variable-speed ECM blower motor. The two stages let the furnace run at lower output in mild weather and at full output in colder weather. The blower adjusts its speed to heating demand, which reduces noise.

Questions and answers

Is the GMVC801005CN worth it over a single-stage furnace?
Yes if you want steadier temperatures and quieter airflow. The two-stage burner and variable-speed blower cost more up front but improve comfort over a basic single-stage unit.
How efficient is it compared with 90%+ furnaces?
It is rated 80% AFUE, so about 20% of the gas input leaves as exhaust. A condensing furnace captures more heat but needs PVC venting and a drain, which this unit does not.
What size home does 100,000 BTU input suit?
The 80,000 BTU output suits medium to large homes in cold climates. Sizing should follow a load calculation, not square footage alone.
Can it be installed horizontally?
Yes. It is configured for upflow or horizontal flow, so it fits basements, closets and attic layouts where a vertical upflow won't work.
What cooling size does it pair with?
It is rated for 2 to 5 nominal tons, so it can carry a matched evaporator coil for a central AC or heat pump add-on.
What venting does it need?
It uses a standard 4-inch vent and is not a condensing furnace, so it does not require PVC pipe or a condensate drain.
Where is the Goodman GMVC801005CN Gas Furnace cheapest?
At acunitsforless.com, for $1,991.00, as of our latest check.
