Overview of the Air Command 90
The Amana Air Command 90 furnace is a discontinued high-efficiency unit capable of reaching up to 90 percent AFUE. According to manufacturerís information dating to 2000, installation of this 40-inch-tall model is flexible, as it is available in upflow and counterflow configurations. The unit is protected from rust and corrosion by a painted steel cabinet.
The Air Command 90 features dual heat exchangers. The primary heat exchanger has a patented tubular design that increases the exchangerís surface area, thereby providing more heat. Instead of allowing air to be vented, the primary heat exchanger captures it and leads it into the secondary, recuperative coil. The recuperative coil is reportedly capable of extracting even more heat to increase the unitís efficiency.
The dual furnace operates in either standard non-direct vent mode or direct mode. The blower compartment and direct-drive blower are sealed for quiet operation, and the blower motor is permanently lubricated. A spark-free surface ignitor is intended to further add to the unitís reliability, and electrical connections for add-ons such as air cleaners and humidifiers are standard in each unit.

We received 28 years out of our unit, excellent heat and low maintenance.

"Carbon Monoxide danger!"
I had this unit's heat exchanger fail while it was still under warranty, causing life threatening amounts of Carbon Monoxide to enter our home. The worst part of it was Amana's customer service is nonexistent. They no longer made the heat exchanger and wanted to give me a cheap Goodman (they own Amana and are the bottom of the line). Every contractor I spoke with told me it is a poor quality unit and the heat exchanger would not last in propane service. Don't risk your family's health. I have spent 1 week in the dead of winter with no heat and have called every Goodman number I can find, and I get nothing but the run around. They have untrained people at a hotline, pretend to take your info and you never hear back from anyone. It is a sham and a joke.

"Amana Air Command 90"
My furnace was installed new when the house was built in 1996. It was selected by my general contractor; I didn't even know that Amana made furnaces. Overall, I've been very pleased with it. One year later we added on a Carrier air conditioning system that has been a total disappointment, but that's another story. I use Filtrete 1000 filters and change them no less than every three months (I have a cat that's been in the family almost as long as the furnace, and he emits clouds of hair and dander). Early on, while still under warranty, there was an issue that required a service call, but I can't remember the specifics. For a long time, we thought the blower motor was under-powered when using it in air conditioning mode, but after review by multiple contractors we believe it is due to insufficient volume in the return air ducting. One item that should be listed as a yearly or every-other year maintenance item is to clean the flame roll-out sensor. This is a metal probe that sticks down into the flame path to see if the furnace successfully lit or not. Over time it gets dirty and doesn't react quickly enough. It's a simple, 3 minute job, requiring only a small nut-driver or socket and a bit of fine sandpaper. Apparently my heating contractor sold a lot of Amana furnaces in my area, and I've spoken with others about their pros and cons. One frequent failure item is the ignitor, which heats up cherry-red (like the broiler in an electric oven) to ignite the gas. My original ignitor lasted for 17 years before it burned out. Other people have a lot more trouble and have to replace them every season or two. I'm told there are two types - one with an oval insulated base, and one with a rectangular base. I think mine was an oval one. After mine was replaced I looked up the part number and you can buy them on Amazon.com for not a lot of money. Other than that, it is going strong as I write this. However, as mentioned, the air conditioner is on the blink again, and since it is 17 years old and uses expensive, harder-and-harder-to-find Freon gas, we will probably replace it and the furnace fairly soon. Obviously you can't buy an Amana Air Command 90 anymore, but hopefully my comments will help those who still have them.

"My 10 year old Amana"
I installed this 70k btu furnace myself with matching a/c converting it to lp immediately. Had a service tech hook up and test the a/c because that takes specialized equipment. In the first two years the following failed: Main control board, flame igniter, a safety pressure switch and the seal around the plastic coil front cover. Since then the igniter has failed three times, and a pressure switch twice. I keep a spare pressure switch (~$30) and igniter (~$10) on the shelf. The igniter can be made to last 3 years by cleaning it with fine steel wool yearly. It's now part of regular fall maintenance! I'm thinking of having a spare blower on the shelf also. I purchased the Amana because Consumer Reports had rated them highly a few years prior. What I didn't know was that Goodman had since bought them out, a lot of the parts have been switched to Goodman part types. I would assume that is for lower cost. When I look for a new furnace I will treat all brands the same and do my research on sites such as furnacecompare.com.

However, these forums also include a range of complaints from homeowners, including problems where the unit starts and stops repeatedly or that the furnace has a burner that will not ignite. One homeowner posting on www.justanswer.com explains an issue where, upon turning on the thermostat on, the fan starts but the burners won't light.
