Overview of the GMH9
The Goodman GMH9 furnace series name is discontinued; the unit was replaced in 2007 with the GMH95, which appears to be similar, if not the same, as the GMH9. The GMH9 achieves a 95-percent AFUE rating, and is a multi-speed and multi-position unit. This furnace is a two-stage gas unit, and the installer can turn on the two-stage valve with a switch. The GMH9 furnace comes equipped with a diagnostic control board to assist with maintenance. The unit features an aluminized heat exchanger and a low-speed constant fan.

This is my second Goodman furnace and it hasn't failed me. What's important for readers of review sites like this to remember is that, people offering low ratings of furnaces aren't mentioning that 80% of furnace breakdowns happen due to lack of maintenance on the part of the homeowner. Given that you use your furnace more than you use your car, it makes sense to get your furnace serviced annually. Alas, people never forget to get their car tuned up but they never tune up their furnaces on a regular basis and they don't live in their cars, they live in their houses. Finally, ALL FURNACES ARE THE SAME. If you take the front panel of any brand of furnace, what you will see is a multitude of parts that are made by third party manufacturers like Honeywell, for example. There are no 100% Lennox, Trane, Carrier, Bryant furnaces just like there are no 100% Goodman, Amana, Payne, or Rheem furnaces. They are just boxes that are assembled at a plant in the US. At the end of the day, the most important thing to remember is that furnaces are designed to work. What generally causes problems is the contractor that the homeowner has hired to install the equipment. If you go cheap, you're going to get a cheap installation where they cut corners and where the furnace is doomed from the date of installation.

"Buyer DO NOT BUY"
J & J heating installed furnace in '06, J & J did not install new TSTAT. Next winter, AC is running with furnace, just filled up tank with 500 gal of propane all gone in 1 month. Next fill up was $800.00 dollars! AC still not working right plus fan runs constant and will not shut off. When I complained to Goodman, they don't care furnace has 5 year warranty but only on parts. They won't even send one of their own techs out to make things right. This furnace is not worth the $5000.00 I spent. Sad that this company sucks so bad even reps are rude. Wish I did the research on this company.

"Very Happy With Goodman"
I have rental houses and have been putting in Goodman furnaces and a/c since 2002. I have put in 8 furnaces and 7 a/c's and have only had one service call in all those years. The circuit board was bad. We had several lightning storms that summer and I think it was hit by lightning. Goodman covered the board and I paid for a service call. I have a Goodman in my house also and have saved a fortune on my utility bills. I am very pleased with Goodman and have recommended them to everyone. I have a hard time believing all the negative reviews posted on this site. I'm glad I know from experience that Goodman makes a quality product. If I had read the reviews on this site I probably wouldn't have bought a Goodman but after multiple units and many years of trouble free service Goodman is the brand I will continue to buy.

I had this furnace installed last year and is much better than my carrier system that I had installed just before I sold my old house last summer, I 'm finding out it's all in the contractor installing it most of the parts are the same but the goodman installer and techs were very critical of there workmanship.

"Nothing but problems."
Year 1 needed a new blower. Year 3 needed a new circuit board (old one looks like it caught fire). Never buy Goodman again.

"NO PROBLEM LOVE THIS UNIT"
GMH950904CX: No problems with this unit in 3 years. Gas bills are much cheaper than my old 80% Armstrong that was always needing repairs. I would buy another Goodman furnace. Next purchase is the dsxc18 Air Conditioner: (1) Up to 18 SEER Performance; (2) R-410A Refrigerant; (3) ComfortNet Communication System; Yeah baby!

"Good Product-Be careful of cheap installers"
I had a goodman GMH950703bx installed Oct. 2010. Installed price was $1200. I paid $280 more to have ac coil added. Will have Ac unit next summer. Ran great until weather got real cold. It would run for about 10 minutes then shut down. I figured out that one of the drain lines was installed on the wrong side of the drain pan. It must be installed on the same side as the outside drain trap. It caused the vacuum hose going to one of the saftey switches to be blocked with water and thus disrupting the electrical conection. I corrected it and the furnace has been great ever since. Good product bad install. I also purchased Amana(Goodman) amvc950453bx for another house two weeks later, same installer. Top of the line Goodman. all Stainless heat exchanger and electronic variable speed blower. It works great & very quiet. It has all Emerson electronics, yes made in China. I took a amp reading of the fan motor and it was 52 watts! Bottom line is find a good installer that will give you a deal on a Goodman because it costs him less money. You can email me if you like email@example.com

This funace sucks! I spent about 10,000 dollars putting it in. My dad just replaced his and his was installed in the 1970'S. wtf?!
