The Goodman GMV9 is a discontinued variable-speed, two-stage gas furnace. The GMV9 was designed for multi-position installation — upflow, horizontal right or left — and had an efficiency of 93% AFUE. It had an aluminized steel tubular heat exchanger and a hot surface ignition system for maximum efficiency. A variable-speed furnace blower motor and two-speed induced draft blower assembly provided quiet operation. It was suitable for direct vent or non-direct vent applications, and had a bottom or side air inlet. The heavy-gauge steel cabinet was fully insulated and had a baked enamel finish.
My Goodman furnace has operated without incident for over 9 years. Unfortunately the blower motor failed (General Electric), and the replacement motor was not cheap. The local dealer (Charest) did a great job of diagnosing and correcting the problem within 5 hours of my call for service. Responsive service goes a long way towards easing the pain of the cost of the repair. In reading other reviews, I believe that it’s a case of “Bad News Travels Fast”. Few, if any, people take the time to write a review if their furnace is working fine. I am satisfied with my Goodman furnace, and their local dealer, Charest Heating & Cooling.
"What a joke"
We have had nothing but trouble since this was installed. Now for the second winter in a row it’s not heating the house, and the fan won’t work when the thermostat is set on “auto”. When it does blow it’s cold air-our house temp is a balmy 59.
"Good investment so far"
I have had my Goodman GMV9 furnace for six years now with no problems. I had it inspected last year. They replaced one switch. I have saved a lot on my gas bill as well. Good price and great warranty. When I need to buy another it will be a Goodman. I live in the upper Midwest.
Other GMV9 Reviews
A consumer on hvac-talk.com asking for comparisons between the GMV9 and a similar Amana unit was told that the main difference is the heat exchanger -- Amana uses stainless steel, Goodman aluminized steel -- and a slight difference in the warranty. Also on hvac-talk.com, a discussion on the quality of the GMV9 found contributors almost evenly divided between good and poor quality.
