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.

"Worked well if it weren't for incompetent techs"

4.0 rating
Somewhat Satisfied

I received this furnace used (as a free hand me down) and has worked well since installed (approx 5 years ago). I had a very incompetent moronic tech replace my thermal expansion valve for my ac. He ended up dripping water inside the whole thing. As a result, I had to replace the circuit board due to it having a burn mark on it. Additionally, it looked like he removed the inducer motor without replacing the gasket; which disintegrated in the process. I, therefore, had a leak in the exhaust, which in turn caused the pressure switch not to engage; which in turn caused the furnace not to ignite. After a quick do-it- yourself, I replaced the inducer motor (which came with a new gasket) and it's good to go. My only complaint is that when I run my heat pump, the fan sounds very loud and noisy (like an airplane taking off). If I leave it on gas (which is cheaper anyway), it's good to go and cheap to run!

Very Satisfied

I have switched from American Standard furnaces to Armstrong Air, and that furnace is bullet proof equipment. The warranty is nice and furnace not any problem. If you need nice hvac equipment, go with Armstrong Air.

Had a new Armstrong furnace and water heater 5 years ago unfortunately the company is no longer around. I have had to have a company come out every year since I've owned it. -40 below on Saturday here and of course my furnace quits again! Another 250.00. I will never own anything from Armstrong!!!!
