Two Stage Variable Speed

Pro Series™ Systems

Pair this model with a Pro Series™ variable-capacity or two-stage air conditioner or heat pump and a Comfort Sync thermostat, for optimum performance. With the Pro Series, you’re in control of every aspect of your home’s climate, as well as your energy costs. Explore the Armstrong Air Pro Series™.

Two-Stage Heating

Rather than being “all on” or “all off,” your furnace can adjust its heat output based on conditions inside and outside your home. So you use less energy to maintain comfort.

Variable Speed Fan Motor

By changing the speed of its airflow during start-up, your furnace can adjust humidity levels and create more even temperatures throughout your home, while enhancing efficiency and reducing operating noise.

Comfort Sync^® A3 Thermostat

When you pair this model with the Comfort Sync^® A3 Thermostat, the system will continuously monitor internal components for optimum performance. Comfort Sync^® puts you in total control of your home environment with remote temperature adjustment from anywhere in the world, even your couch, via smartphone app. When Comfort Sync detects that repairs and regular maintenance are needed, it alerts you or your dealer instantly, so your perfect environment never ends.

96% AFUE Efficiency Rating

This means 96% of your fuel is converted into usable heat. Compared to an older furnace, this can potentially save you hundreds of dollars per year in energy costs.

Quiet Combustion™ Technology

Uses a smaller Btu input per burner for quieter start-up and operation while providing more even heat distribution.

Advanced Heat Exchanger

Made from stainless steel for maximum strength and crimped, rather than welded, Armstrong Air heat exchangers are highly resistant to thermal fatigue and other stresses caused by repeated heating and cooling. During the testing process, they are subjected to temperatures that far exceed normal operating ranges, to ensure they will stand up to years of use.

EHX™ Technology

Every Armstrong Air furnace is engineered and built with EHX Technology, a patented design that eliminates the hot spots that can shorten furnace life. EHX Technology makes heat exchangers more durable, and with its advanced airflow system, more air contacts the heat exchanger surface area for greater heat exchange, enhancing efficiency and comfort.
