Armstrong Air
A931A High-Efficiency Single-Stage Furnace

A931A Gas Furnace Resources

Top Features of the A931A Gas Furnace

  • 93% AFUE Efficiency Rating

    This means 93% 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.

  • 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.
