The Goodman GMVM97 is a two-stage-modulating gas furnace rated at 97% AFUE, with a variable-speed blower and 100,000 BTU input. The modulating gas valve and variable-speed motor let it run at low, steady output instead of cycling on and off, which keeps temperature swings small and airflow quiet. It suits homeowners replacing an older single-stage furnace in a cold climate, especially paired with a matching coil and thermostat. Against premium modulating furnaces from Carrier, Trane and Lennox, it offers the same core efficiency and comfort features with fewer dealer-network extras and a shorter standard parts warranty.

Owners and installers describe the GMVM97 as a solid value modulating furnace that heats evenly and runs quietly on low fire. Complaints center on the need for a matching thermostat and on installation and condensate details rather than the furnace itself.
This is a 100,000 BTU natural gas furnace with a 97% AFUE efficiency rating. It is part of Goodman's top-tier furnace series, model GRVM971005CN. It has a modulating gas valve and a variable-speed blower motor.
The furnace has an input of 100,000 BTU and an output of 97,000 BTU. It is designed to heat a small to medium house in ideal climate conditions. Because it is a condensing furnace, it requires plastic or PVC flue venting.
It can be installed in an upflow or horizontal orientation. It can be converted to propane with an LP conversion kit, which is sold separately. The design is aimed at electrical efficiency, safety and lower sound output.
