Armstrong Air
A951SHigh-Efficiency Single-Stage Furnace

A951S Resources

Top Features of the A951S

  • 95% AFUE Efficiency Rating

    This means 95% 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.

  • 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.
