97% AFUE Efficiency Rating-This means 97% 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

Dual-Fuel Compatible-The combination of a gas furnace and an electric heat pump pairs two energy sources for the perfect balance of energy efficiency and comfort

COMFORT-Modulating Heat-Provides superior comfort over traditional single- stage and two-stage products, further reducing temperature swings in your home

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

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

One-Touch Away Mode-Puts your system into an enhanced energy-saving mode when you leave

Remote Access-Allows you to check and adjust your home's temperature from anywhere using your laptop, smartphone, tablet or other web-enabled device

Weather Data-Using its connection to your wireless network, Comfort Sync can display a five-day forecast and live weather alerts

Insulated Cabinet-Prevents loss of warm air while reducing noise from the motor

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

Internal Monitoring-Your Armstrong Air furnace's electronic control system prolongs system life by continuously monitoring internal components for optimum performance and fault prevention
