Overview of the GMH95
The Goodman GMH95 is a two-stage, high efficiency gas furnace with an efficiency of up to 96% AFUE. This Energy Star approved unit uses a four-speed direct-drive circulator motor that consistently operates on a lower function to save energy. When the system detects a change in temperature, the motor automatically transfers to a higher heating stage. The multi-speed motor, along with an insulated cabinet, contribute to quiet operation.
Other features of the GMH95 include a silicon nitride ignitor, an aluminized-steel tubular heat exchanger, an electronic control board with self-diagnostics, and an auto-comfort mode that aids increased air quality and dehumidification.

"I couldn't recommend a better furnace."
My wife and I purchased our Goodman furnace two years ago, after our old one failed after 30+ years. Knowing that our prior unit was a Lennox we were reluctant to switch brands to one we had never heard of before. But, I'm very happy we did. The newer unit is smaller and more compact and installation of the unit was quick and painless for the contractor we hired to install it. The efficiency of the unit was immediately noticeable in our gas bills, and the house stayed nice and toasty warm during the winter. The best part is how quiet that the unit is. We have a "man cave" in an adjacent room and the old unit was loud and obnoxious. The Goodman is much quieter than the older unit and that means I can watch my TV in peace. The unit also came with a great manufacturer's warranty in case something did happen to go wrong, but up to this point it's ran perfect and we've only had one visit for general maintenance. I've recommended this particular furnace to many friends of mine and I would definitely recommend it to you too.

"Five years; 2 Goodmans; no problems"
As an electrical engineer I have self-installed three furnaces successfully over the years in two homes. In 2009 I replaced a 25+ year old 60,000 BTU gas furnace in our vacation home with a 96% efficiency, 46,000 BTU Goodman, carefully following all instructions. It required doubling to tripling capacities of hot and cold ductwork to correct longstanding cold areas and keep temperature rise to the lower end of the desired range. Gas manifold pressure had to be reduced somewhat to reduce input heat to the rated level, based on gas meter/time readings. I accepted the fact that my internet purchase and self install would invalidate any warranty and disallow any utility rebate, but cost savings were so great that even having to quickly replace the whole thing would still be less expensive than hiring a "professional". I was also disturbed by the inept/poor quality of the original installation in that home and in neighbor's homes from the same era by so called "professionals". My installation went so well and the furnace worked so well that I also decided to replace my old oversized 100,000 BTU principal home furnace with the same much smaller unit. It runs only 12 hours on the coldest days, showing the effects of added attic insulation over the years and more reasonable furnace sizing. Ductwork for an old 100,000 BTU furnace is about right for a modern high efficiency furnace of half that size. It does take 2-3 hours to reheat the houses to 70 degrees from an overnight 64 degree setting, but that is easily done by two 3-degree jumps in the programmed thermostat setting beginning 3 and 1 1/2 hours before you want it warm. Both furnaces have worked flawlessly for over 5 years, with only the purchase of as yet unused spare igniters. One has run several times for up to a week on a 1500 watt generator when power failed. The furnace control board does require that the neutral and ground connections be bonded together at the generator or it fails with an error code. Note that it is highly desirable to use a high efficiency air filter to keep the furnace clean. I currently use a MERV 13 filter with substantial air resistance that greatly reduces air flow and increases temperature rise across the furnace. Contrary to popular belief, the reduced air flow reduces the electrical consumption of the blower and saves as much in electricity cost as one spends extra for the better filter. As long as temperature rise is acceptable, better filters will probably make the furnace last longer. This review was prompted by a neighbor who, without consulting me, recently had to have his very old furnace replaced because he thought he was smelling fumes in the house. A so-called "professional" installed an oversized furnace, leaving his wholly inadequate duct system. The result was the furnace operated for five minute periods, tripping the over temp limit switch and then cooled down until it reset, over and over and over. This just proves to me that proper installation is still the key to success and may be hard to get. Furnace brand is of much less importance, because most use the same components. As far as maintenance, I check the igniter resistance, replace the air filter, check gas consumption at the gas meter, check flue gas temperature and temperature rise across the furnace and listen for any unusual sounds. I think the induced draft fan has gotten noisier but is still acceptable. I, for one, am totally satisfied with the five-year performances of my two Goodman furnaces, despite living with no warranties.

"Buyer beware - Goodman furnaces are total junk!"
We installed a 2008 model Goodman furnace in 2009. Last winter, we had a long, long cold streak and I had 6 different HVAC guys out to try to repair it. The last guy finally replaced the motherboard and it worked fine after that. Now, here we are in 2014 and the first cold spell of the winter, and no heat again! Last year I had to spend $941; so far this year, $144. Plus, last year we had to stay in a hotel for 4 nights because we couldn't get anyone to come and fix it due to the prolonged cold weather. Last year, when we tried to file a warranty claim for the control hoard, we were informed that because we didn't call them when the furnace was installed, our warranty ended after just 5 years! What a crock! Never, never take a chance with this crappy furnace! Buyer beware! Save your hard earned money!

"Less than 2 years"
I just had the motor replaced after not even two years. I don't care about the warranty, this product should be built well to start. This is not a good sign of things to come. I should start putting funds aside to replace this thing in another two years. If I'm lucky, it'll make it that far.

I have had my Goodman for 4 years with no problems. This furnace came recommended by my local repairman who regularly worked on my dying Trane.

"Best Gas Furnace Ever in USA"
I owned this furnace from the past 2 years. I do have a warranty for 10 years on every part of it and Lifetime Heat exchange warranty. I don't have any dislikes till now. I don't have any repair or any of the parts replaced from the past 2 years. I had already recommended the same brand to some of my friends and 3 of my friends already bought the same furnace. I really like the speciality of the Goodman Furnace in respect to the customer service and even if we have any complaints they tried to reduce that as soon as they can i heard that from all my friends and i assume that if this is what happens to every customer of the Goodman, Definitely Goodman will be the successful and i hope them to continue their well being in the future times also.

I purchased the gmh95 because the repair was half the amount of the furnace repair. I have seen a 15% decrease in the natural gas bill.

"Works as well as it is installed"
Let me just say first off, I am not an HVAC technician. I am, however mechanically inclined. I bought a gmh95 unit off the internet last spring to replace my 6 year old fuel oil unit that tried to kill me in the middle of the night last winter by lighting my face on fire while trying to get the stubborn old beast to reset. I switched to propane with this unit for 2 reasons. 1: The price of fuel oil has skyrocketed in the last 5 years I have owned this home. 2: Natural gas is not available in the rural area I live in. That being said, I am the type of person that studies, reviews and mulls things over for months before making large purchases such as a furnace. After getting estimates from local HVAC companies ranging from 4k to 5k for the type of furnace I wanted, I decided to buy and install the furnace myself. I chose the Goodman mainly due to price. In all, I spent around 2k including rental of a propane tank and having it set, a new plenum, return air drop, gas lines, and fittings, exhaust and fresh air lines, and fittings, glue, and all the other small bits needed to do the install. I read over the installation instructions 3 or 4 times and one Saturday morning, I tore out the old unit and proceeded to install the new Goodman unit. It took me a day to do everything having the installation book to refer to with me the whole time. I installed this furnace exactly as the instruction booklet told me to. This furnace runs flawlessly. I see people on here complaining and complaining and complaining about these units. I can understand a unit here or there having a problem from the get go as nothing is ever perfect and sometimes shit just happens and you will need to bitch at your installer or the manufacturer. On the other hand, there are people installing these things themselves that don't know what the hell they are doing or they have paid an installer that doesn't know or care what the hell they are doing. Improperly sized duct work and/or units with not enough vents are going to overwork your blower motor and burn that sob out in no time at all. The same goes for all you people that are too damn lazy to change your filters on a regular basis. Improperly sized fresh air and exhaust lines on the high efficiency models are going to cause all kinds of hell with the system. Dirty oily fingers touching the new ignitor when the old one is being replaced is going to cause premature failure of the new one.(By the way...the hot surface ignitor is a common repair on all furnaces using them rather then a spark type ignition) There are two types of these hot surface ignitors also, silicone carbide and silicone nitride. The silicone nitride will last as much as twice as long as the carbide model at a bit higher cost initially. Keep an extra one around and install it yourself when the one in the furnace burns out. Its 1 screw and one wire connection to replace it usually. Lets also mention that for those of you that may have a Goodman unit that was converted to propane when installed that the pressures for it must be set with a piece of equipment called a manometer to assure proper flame so as not to soot up or otherwise prematurely wear out your heat exchanger. Do any of you that have complained about premature heat exchanger failure route your clothes dryers exhaust into the house to capture the heat and humidity? That will kill your heat exchanger in a hurry too. Or even wet stale basements can do it. Or for those of you that say "Well, I have a brand new house blah blah blah". Do you have an air exchanger in the brand new house that's built so tight that when you slam the front door the toilet flushes? All that humid air needs to be replaced or its going to eat up your heat exchanger and corrode connections etc etc etc. My point is stop blaming the unit you bought when most likely its your own damn fault or your installers. Yes, it's hard to find a contractor you can trust but damn people, you have the internet to bitch so why don't you try using it to educate yourselves a little bit before you hand some dill hole a check for 5k and think everything is going to be like Alice in Wonderland. My only regret with the unit I purchased off the internet and installed myself is that I wish I had gone with the variable speed model rather then the multispeed unit I did get. I would have liked to have had control of the stages at the thermostat which isn't possible with the multispeed unit. If I had made that decision when i bought this unit, I would have give in this unit a "very satisfied" rating rather then the "somewhat satisfied" rating I did give it.

"Love my Goodman furnace."
I had a Goodman gmh95 series installed and I love how whisper quite the unit is. When it comes on in low, you can barely hear that it is on. Even after it switches to high, there is only the whoosh of air coming out of the ducts. The unit has a nice appliance grade finish and rubber gommets or seals to guarantee silent operation. I did a lot of research before buying a Goodman and talked to several hvac friends,home inspectors, and contractors and if the Goodman is installed correctly, it is a good furnace with a very long warranty.
