A951E 95% Single Stage Constant Torque Furnace

Constant Torgue furnaces are just one more way Armstrong Air helps you enhance your homes efficiency and comfort. Every A951E furnace is built with smart thinking throughout, from the advanced motor to Quiet Combustion technology.

  • 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 decades of use.
  • Constant Torque Motor Maintains a more consistent airflow than a single-speed PSC motor, keeping you consistently comfortable. The motor also operates with greater efficiency and less noise.
  • Quiet Combustion Technology Uses a smaller Btu input per burner for quieter start-up and operation while providing more even heat distribution.
  • Internal Monitoring Your Armstrong Air A97MV furnace‚Äôs electronic control system prolongs system life by continuously monitoring internal components for optimum performance and fault prevention.
  • Dual-Fuel The combination of a gas furnace and an electric heat pump pairs two energy sources for the perfect balance of energy efficiency and comfort.
