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.

"Excellent Furnace"

5.0 rating
Very Satisfied

If your furnace is installed by a quality tech, you likely won't have any problems. I've had mine running for 5 years, in Canada, so it works hard year round. No issues at all, in fact I thought it had started to fail, but it was just a sticker from the inside of the service panel that had fallen onto the fan motor. 5 second fix. People that are having problems should seriously look at the quality of the tech that is doing the installing/repairing.

"Goodman Furnace quality"

3.0 rating

I have been in business for 18 years. We mainly sell 90% Trane and Roughly 10% Goodman. Goodman seems to be a lot better quality than they used to be 20 years ago. If you have a GMX or GMT I'm sorry. But to make a long story short. We sell mostly Trane. But on the shelf, we have mainly Goodman parts. Does that tell you anything? We stock 2 inducers and we can get them replaced the next day. In other words we have had two Goodman inducer failures the same day. Heat Exchangers, we change a few of them every year. And to date, only 1 failure in the Trane, (which the lady refused to change air filiters) Her fault. Now Goodman is getting really proud of their furnaces and the prices are going up, as much as the Trane. So which do you suppose we push more of. It has been suggested by our employee's to push more Goodman for job security, but we prefer sleeping all night long without call outs if we can.



"Service Friendly and Cost Friendly"

The engineers must have been HVAC service technicians. This company is not well known, but it should be. Goodman is a very good manufacturing company. Goodman designs what a furnace and air conditioner is supposed to do, heat and cool. Other manufacturers add all these 'bells and whistles' which makes troubleshooting more difficult and makes home owners upset because of the high repair bill. I highly recommend Goodman.

My 93 year old mothers 4 year old Goodman furnace went out in the middle of the night , on a -30/-35 wind chill night in wi. She called her original installer but he could not come until morning. At 10:30 pm it was already 61 degrees, what would it have been at 10 am with wind chills -30/-35 during the night. We called an emergency service, he had to replace a burned out motor. He used a universal motor as that is what he had. Now Goodman will not cover the warranty as it was not a Goodman motor. I was even told by one customer service person that the work was not done during the day to it is not covered. It makes me sad that a company can be set on specific time , place, item that they are willing to let a 93 year old lady freeze. Very disappointed they will not stand by their product in the middle for the night. I am telling everyone I know they do not stand by their product.

This furnace is garbage and it is not even worthy of being given away as a gift .This was really a bad investment I wish I had never purchased it.I Have only had it for a few months and I have endured nothing but expenses and headaches.The manufacture know they took advantage of the people on selling this mess.They can blame the hvac techs but they messed up .
