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.

Very quiet. Seems to ramp up and down like dealer told me it would. Better than my neighbors Bryant unit.

I have had an Armstrong Air unit for a long time now. Other then a small repair it works very well and I'm happy with the quality. You will be lucky to have this unit. I hope your installer is good. A good installer is always key.

"Good unit big changes made"

I bought an ac and it was a great success. No surprise I talked with the installer and decided to buy a furnace and have a great brand new system for both seasons. The unit is Lennox quality and shares almost all same components. Price is better. So you save, get a solid unit and have the same warranty. I like what Armstrong has for both seasons for your house. Thank my later 🙂
