Multi-Stage Performance and Variable-Speed Blowers

Armstrong’s line of multi-stage furnaces with variable-speed blowers feature AFUE ratings ranging from 80 to 97 percent. The highest efficiency units feature modulating heat, while the remaining units have two-stage heating.

All models in this series are equipped with a stainless steel or aluminized steel heat exchanger and Armstrong’s Quiet Combustion Technology, which uses a smaller Btu input for each burner to keep startup and operation noise to a minimum. Several of the models in this series are Energy Star-certified.

Single-Stage Performance with Constant Torque Motors

Armstrong manufactures two models of single-stage performance furnaces with a constant torque motor. Designed to provide consistent airflow and quiet operation, the constant torque motor helps increase overall system efficiency compared to other styles, according to the manufacturer.

Models are available with 80 or 95 percent AFUE. They feature Quiet Combustion Technology, an aluminized steel or stainless steel heat exchanger, and Armstrong’s EHX Technology designed to eliminate hot spots and increase the unit’s lifespan.

Single-Stage Performance

Although Armstrong’s line of single-stage performance furnaces lack the special features of the manufacturer’s top-tier product lines, these models do offer equally efficient heating. With four models available, single-stage performance furnaces range from 80 to 95 percent AFUE.

Quiet startup and low operation noise, EHX Technology, and an internal monitoring system to prevent system malfunctions are among the features of this series.

Oil-Burning Furnaces

Armstrong offers variable-speed blowers and single-stage performance from its oil furnaces. All units offer feature an 83-percent AFUE rating. These models use Beckett Burners and an insulated cabinet that keeps the warm air in and noise levels low.

Care and Maintenance

Armstrong advises annual maintenance from a service technician prior to the start of the heating season. Most manufacturers encourage homeowners to clean their filters regularly for maximum furnace performance.


Every Armstrong furnace comes with a limited lifetime warranty for the heat exchanger and a 10-year limited warranty on parts, so long as the product is properly registered shortly after installation. The manufacturer’s warranty begins on the date of installation.

"Armstrong Furnace"

Very Satisfied

I've had my Armstrong furnace for 26 years and only had 2 repairs in that time. One repair was the control board and the other repair was the spark controller. I could have had the furnace longer but decided to put in an American Standard. I was very satisfied with the Armstrong product.

"Plan to spend plenty on repairs each year. Sometimes twice a year."

1.0 rating
Very Unsatisfied

We purchased an Armstrong Ultra V Tech 80 in 2008 from a heating/cooling company. We needed repairs in 2010 and every year thereafter. Sometimes twice a year. I'm writing this review only now because I am fed up with having to spend so much money each year for repairs. I called a repairman today because the heater will not go on. Second time this year for service. I have used several different companies when I needed service so this is not related to knowledge or lack of. A couple of repairmen said this product keeps them in business. Product reliability is not Armstrong's best attribute. I read their reviews on this page and others and I am not the only one with concerns and complaints regarding Armstrong's product quality. So, will I ever buy Armstrong or recommend their products? —NO—NEVER– I"M done..i added up how much I have spent since 2010 excluding today's service call. $1849.16.. and still going strong….Please, when deciding to replace your furnace and air conditioner check other manufacturers. Thanks–Jay

"Stay away from Armstrong"

We purchased an Armstrong high efficiency furnace with our new build 3 years ago. Three years in, the Armstrong furnace has malfunctioned every year without fail. Each year the technician replaces the pressure switch, citing poor quality pressure switches. I will never buy Armstrong again.
