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.

Installed 3 years ago. Changing the filter is a total pain in the ass. Three holes in the lower door, which is the contact, must line up with three holes in the upper door. Then you need a magnetic hex screwdriver to insert three screws if you have three hands: One hand to force the lower door down, one hand to keep the upper door firmly locked in place, one hand to insert the Hex screws. I checked- no other manufacturer has such an owner-unfriendly setup. Most have a simple hinged door, open lift out a filter, insert new.

Total garbage. 5 years old and won't ignite. 4 Goodman plumbers can't get it fixed.

Simple to install. Just a little noisy. Fine if it's in the basement.

"Goodman contractor review"

Very Satisfied

HVAC contractor of 32 years. Several brands in my tenure and the last 6 years went with Goodman and can honestly say, it is a very well built unit. Many models and have very, very little failure within these 6 years, less than any other brand I have sold! I was not too much of a fan before they started to produce the quality units I sell now. Excellent factory support also. Anybody that is giving Goodman a bad review was just not given the correct installation and professional job they should have gotten.

I am a heating contractor. Installed new line off Armstrong air furnace because Goodman furnace is big garbage. It's not honoring warranty, not labor warranty, not paying contractor work. Do not deal with Goodman anymore. It is the biggest garbage equipment on the market.
