Goodman Furnace Overview

Goodman makes eleven types of gas furnaces, which the company separates into a ‘standard-efficiency’ class and a ‘high-efficiency’ class. Efficiency is measured in AFUE, which stands for ‘annual fuel utilization efficiency.’ The AFUE number reflects the percentage of heating energy that gets converted to thermal energy for a house.

Most of Goodman’s furnaces use heated aluminum coils; some have secondary heat exchanges made from stainless steel. They are all gray in appearance and have highly durable finishes to protect their exterior.

Standard Efficiency Furnaces

All of Goodman’s standard furnace models list AFUE of up to 80%. The standard efficiency models include:

There are several features distributed among these models, in various combinations.

Multi-Speed. Multi-speed heaters can save energy because they can operate at various different levels depending on the amount of work that needs to be done. Goodman’s multi-speed heaters have four different operations.

Variable Speed. Variable speed furnaces operate according to a similar principle, but have the capacity to vary their speed across a continuous range, instead of providing discrete options.

Multi-Position. “Multi-Position” furnaces can be installed in different positions. This might be useful to homeowners who need to fit a furnace into an unconventional location.

Silicon Nitride Igniter. Electric igniters can increase energy efficiency because they don’t require gas.

ComfortNet Compatibility. Some of the furnaces are compatible with Goodman’s ComfortNet, a system that monitors temperatures in order to create efficient and rapid responses from the heating system. The system includes a thermostat display and can be connected with four wires to the main unit.

Goodman’s High Efficiency models include:

  • GMVC95
  • GCV95/9
  • GMH95
  • GCH95/9
  • GKS9

These heaters range in efficiency from 92% AFUE to 95% AFUE. Some of this efficiency is due to better insulation; some is due to more sensitive control over the heating function. Many of the same combinations of features as above are available.

Some of the efficient furnaces have two stages, which means that in addition to operating at multiple or variable speeds, they engage a separate component for heavy-duty heating. This process is relatively energy efficient. Two of these models (GCVC95 and GCH95) are downflow furnaces, which means that cool air enters at the top and is heated by rising warmth from the bottom. This is an efficient model because the heat was going to rise anyway.

The ‘top model’ of this bunch is the GMVC95, which has a 95% AFUE, two stages, and variable speed. It has a dehumidification element and an electronic control board that allows individualized control over its various elements.

Care and Maintenance

Goodman recommends homeowners work with a professional contractor for maintenance purposes, and that they schedule annual tune-ups for their home’s central heating system.

Many homeowners change out the filters in their furnaces. We have covered common Goodman filter replacement questions, here.


Most of these models come with ten-year limited warranties for their parts. The top models also come with lifetime warranties on their heat exchangers . The promise of additional maintenance can be purchased through the GoodCare program.

Replaced our almost 30 year old unit in September 2013, which was not a Goodman, with this brand big mistake,they may offer a 10 year warranty, but have seen the repairman in July for air conditioner blower went out, in December for flame sensor issue and 2 months later in February 2017 for igniter, flame sensor and some switch, not to mention the previous years issues. Do not purchase they will dollar you to death with service calls and sensor cleaning needs to be in the junk metal scrap pile.

My furnace and ac system were installed in 2006 and I have done some basic cleaning and changed filters so far and have never even had a serviceman do his recommended maintenance thing or had a problem until the fall of 2016. It has always worked great until this fall when it did not perform consistently. No internal parts have even been cleaned or replaced until this problem occurred. It had failed to start after its 3 initial attempts. I then replaced the circuit board which appeared to clear the intermittent problem for a while but the problem still did not disappear entirely until I replaced the thermostat with a different make and model. Apparently it was no longer working in a compatible and reliable manner with the furnace board and had me fooled into thinking it was the furnace acting up. I will eventually reinstall the original board again just to test it to see if it needs to be discarded or still kept as a spare part now that it is running great again. While doing this I had discovered it also was acting as if the air intake pipe was restricted since it was running good with the door panel loosened a little so it would pass a little air through it. I increased the pipe size to 3 inch which is optional but preferred depending on the pipe length and number of bends. It was installed with a permit by a furnace contractor and did pass inspection by the city inspector with the smaller size pipe. This still did not help correct things so I inspected the inducer blower. I removed it to inspect and run it and determined it was still working fine but noticed the pressure port barely had a clear passage through it to the blower wheel from when it was plastic molded. I drilled out the excess plastic molding flash and it is now running good at 100% again with a tightly sealed door panel. The small restricted passage was more prone to a clog but it had still performed great for over ten years. For those who say their Goodman is junk — Improper installation as well as a service person who cannot instantly diagnose a simple but uncommon problem can make someone refer to something as junk when nothing but dirt is the only problem and no parts are even needed. It sometimes just takes time to figure out an unusual problem that is intermittent and hard to diagnose that may not even require anything more than a persons time and patience to eventually correct.
