Overview of 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.

The heater was purchased in 2008 and already has carbon monoxide fumes coming
out. I need a new heater.

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.

Anyone know of a class action suit?
Paid for high quality and got expensive problems. Blower motor is out
and am looking at $1000.00 to replace.

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;

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 protected]

Goodman funaces suck!
I bought a new supposed 95% efficientcy furnace and have only had it
operational for one winter, well, kind of, it hasnt operated for more
than a week! The Model number is gmh950453bx. 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?!
Other GMH9 Reviews
A homeowner, who owns a Goodman GMH furnace, writes on diychatroom.com about a noise his unit is making. An expert answers that it sounds like the motor mounting may be loose, especially if the furnace was installed horizontally. The homeowner seems to agree that this could be the problem; it is not considered a major repair job.
A potential GMH customer asks for advice on hvac-talk.com. The post states that a contractor wants to install a Goodman GMH furnace in the customer's 1,200-square-foot home. One expert responds that the particular model the customer is mentioning would probably be too large for that size home.
Another potential customer asks for advice about the Goodman GMH furnace on hvac-talk.com. The online experts answer that these furnaces provide comfortable heat for an affordable price. They do mention that the two-stage heating cannot be controlled by the thermostat, so the run cycles for the heat are not very long.
The GMH9 is available in different models which vary in efficiency and capacity.
