80% AFUE Efficiency Rating - 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

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

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
