Engineered Longevity

A gas furnace is a piece of equipment from which you expect years of uninterrupted service. Amana® brand gas furnaces live up to expectations through intelligently designed components that benefit from decades of performance testing and refinement, like our new stainless-steel heat exchanger. And with outstanding warranties* that demonstrate our confidence, you can purchase an Amana brand furnace safe in the knowledge it will Last and Last and Last®.


Quiet Comfort

Many homeowners may think the best gas furnaces are not seen or heard. That’s why an Amana brand AMH8/ADSH8 Multi-Speed Furnace is insulated for noise reduction. With a sound-isolated blower assembly and a heavy-gauge steel cabinet, it offers quiet performance compared to units with single-speed motors.


Energy Efficiency

Energy efficiency equates to cost savings. A gas furnace’s efficiency rating can primarily be determined by two factors: its AFUE rating (Annual Fuel Utilization Efficiency), which indicates what percentage of each dollar of natural gas purchased is actually used to heat your home; and the type of blower used in the furnace.

Product Limited Warranty+

If the heat exchanger in this gas furnace ever fails for the original, registered homeowner, we will provide a new furnace. This furnace also has a 10-Year Parts Limited Warranty* on all functional parts at no cost. For a full description of all warranties applicable to this product, please see your local Amana dealer or click on the consumer brochure and product warranty links above.

Unlike conventional, single-stage furnace technology, our patented convertible technology eliminates the temperature swings resulting from abrupt, high-stage stops-and-starts of the furnace by operating at a low heating state the majority of the time. This gas furnace has an AFUE rating of 80%, which means that 80 cents of every $1.00 of heating energy expense warms your home.

Rated 5 out of 5 by from Game Changer Have a commercial building that was built with electric strip heat. Installed two of the in line Amana natural gas fired heaters. They work great and have drastically reduced my energy bills. My office maintains warm temperatures even with temperatures as low as 11 degrees outside.

Rated 4 out of 5 by from Good value for money! I bought this on June 17, 2016, and haven't used the furnace function at all yet, so it's really too early to write a review,

Rated 5 out of 5 by from So Far, So Good...Quiet, Powerful, Cool... Had to replace an older A/C unit that had died, was recommended the Amana 4 Ton. So far, so good. Works like a champ. 10 year parts warranty, hard to believe! Don't quite know about the efficiency or the money savings yet, but was told we should see a 30% or so drop in the electric bill. We shall see as we enter the Vegas Summer ahead. Thanks.

Rated 5 out of 5 by from Cooler AND efficient Only a month but what a difference. My old unit ran constantly and never cooled my house off like this new unit does. Replacing major things around the house is never fun, but it makes it a lot easier when the product actually works like the installer says it will.

Rated 4 out of 5 by from Just bought this last week, so I haven't needed to use the furnace yet. But it looks good and we look forward to using it in the winter. This one replaced an Amana that was original in the house - lasted 30 years!!! So, of course we went with another Amana.

Rated 5 out of 5 by from AMANA is "WAY...COOL and HOT!" I am so thrilled with my new unit. It is very quiet and cool! My 32 year old tri-level home had always been difficult regulating the temperature and would only cool/heat one floor comfortably. The basement was cold in the summer and the top floor was hot. It was the opposite in the winter. With my new unit, the temperature is regulated and comfortable on each level.
