Armstrong Air
A801ESingle-Stage, Constant Torque Furnace

A801E Resources

Top Features of the A801E

  • 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.

  • 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.
