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

Constant Torque Motor-Like a variable speed furnace, constant torque furnaces provide lower operating costs and increases to overall system efficiency Compared to standard PSC motors, constant torque delivers more consistent airflow and quieter operation

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

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

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

Limited Lifetime Warranty on the Heat Exchanger
