Goodman GMNT Furnace Overview

I’ve owned this furnace since 1999 when I bought my house that October. It wasn’t new then, maybe a few months old or so at the time. I like that it’s almost been 20 years and I haven’t had a major problem with it. The igniter stopped working a few times one winter. This was about 5 years after I bought the house. Needless to say, I spent more than expected to get that fixed but it was good from there on out. I was also told during that time that there was an air flow problem that also got fixed that day. The repairs happened swiftly and went extremely well. I haven’t had a problem since. Now that I know a bit more about the brands, prices and quality of other companies, I might not buy this brand again. I personally haven’t had any problems with it and yes, I would recommend this product to anyone. On the other hand, there are cheaper brands out there with better prices, cheaper costs when it comes to managing the equipment, and better quality of the products in general.

Had this furnace 11 years. There have been a series of problems, starting with a failed circuit board and three igniter replacements. This has been an uncomfortable furnace in our house because, to extract the last amount of heat before shutoff, the discharge temperature would go very low, creating draftiness throughout the house. I had the HVAC mechanic look at it, but was told the limit could not be reset. Last winter the blower motor started acting up and there was a smell of burning sometimes through the house, which I thought was burning motor windings. The blower became increasingly harder to start, which I attributed to failing bearings creating additional strain on blower start. In replacing the furnace now, we find the burning smell was the plastic drain pan underneath the “A” coil. There is considerable melted plastic and soot on the heat exchanger. It is puzzling why the high temperature limit would not shut the unit off, creating a very unsafe condition in our attic. Needless to say, our replacement furnace is NOT a Goodman.

In 3 months time we replaced collector box 4 times, had to replace the inducer assembly 3 times within 2 years and had to replace the blower motor. It is loud and once again we are having problems with it. We replaced inducer assembly 1 week ago and the little sensor has to be bypassed to keep furnace running. Manufacturer is of no help. Goodman is junk!

In the 7 years I have had this furnace, the igniter was replaced once. It works excellent and provides an even heat. Save about $150 a month during the heating season. And yes I installed it myself. I had a heating contractor check it our before start up. I would not hesitate to purchase another Goodman.

Installed this furnace 7 years ago and haven’t touched it since. I just change filters and make sure the flame is blue and it hasn’t let me down. Correct installation is key for any furnace. Sounds like too many of the reviews here are from improper installation!
