Goodman reports that its GKS9 gas furnace was built for reliability and efficiency. Its dual-diameter tubular heat exchanger is crafted from aluminized steel and uses a “wrinkle bend” technology, which the manufacturer says adds to its durability. The furnace control board is self-diagnostic and has a low-voltage terminal block for easy control of the unit. This model features a 4-speed circulatory motor for uniform heating and a single-speed induced draft blower, which assists in the energy conservation aspects of the furnace. The blower is sound-isolated. The Goodman GKS9 gas furnace has a single-stage combination redundant gas valve and holds a 92 percent AFUE rating.
The corrosion-resistant cabinet is designed for upflow installation, but it can easily be converted to a horizontal left or right position with a pressure switch kit. The bottom of the cabinet is constructed with airtight solid steel for enhanced return applications from the sides.

I purchased goodman furnace in Jan 2011. Igniter broke into two pieces. They gave me in writing 10 years of parts warranty. I call them and now they are telling me that a certified licensed contractor needs to do the job of replacing igniter. In short the warranty sucks. They want me to hire a contractor who will charge me at least 100 bucks for replacing a part worth 20 bucks. No more goodman products ever for rest of my life.

This is the first winter it has gone thru and the blower runs constantly, contractor says its junk but the Goodman Company won’t stand up to warranty. I am going to contact bbb and make complaints. See where that gets me? Lol

I got my goodman 92% furnace 8/07 90000 btu gks9 model. on the advice of my installer. he said was the best bang for the buck. I researched and read all the bad press. he said that was the older models. he also sells trane and told me his own furnace was a goodman. this is the third full winter and not a problem. my old furnace worked fine a old bryant but my gas on the budget plan was $378 a month since we got the goodman. the budget amount has come down to $115.00 a month some of the savings came from new windows. but the furnace has paid for itself. the lesson here is go with a good heating and cooling company.and listen as they explain. what they suggest and why.I Had to bids on the install the 1st bid said get a 70000 btu airflow. the 2nd said the 90000 btu and why because of the size of my house he said the 70000 btu my run more often to heat the. even though he sold trane. he did not try to push it on me. the 1st bid did try to steer my toward a lennox.I Could have bought a trane or lennox but would have not been able to change as many windows. which 2nd bidder thought was important also. I agreeed
Other GKS9 Reviews
A review on furnacereviews.com relates the GKS9’s inconsistency in heating performance. These heating variations appear to be more inconsistent during extreme winter conditions, according to the reviewer. Unfortunately, the reviewer on this forum has no clear-cut solutions to addressing this issue, other than staying on top of regular maintenance.
Some consumers also have complained about the system malfunctioning due to improper installation or maintenance by inexperienced technicians. For example, a consumer posts on justanswer.com a question about the unit’s limit switch, which turns out to be difficult to reset. The homeowner suspects the problem began when a technician replaced the unit’s blower.
