Pro Series A97MV High Efficiency Modulating Gas Furnace

Pair this model with a Pro Series™ variable-capacity or two-stage air conditioner or heat pump and a Comfort Sync thermostat' for optimum performance. With the Pro Series' you’re in control of every aspect of your home’s climate' as well as your energy costs.

Professionals in the HVAC industry choose equipment built with the highest level of craftsmanship and engineered with the most energy-efficient features available. An Armstrong Air A97MV furnace delivers on both counts. Quality construction assures years of reliable operation' and modulating technology provides efficient warmth even in the harshest of winters. It’s home heating at its best. It’s why it has been named ENERGY STARs Most Efficient furnace.

  • 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.
  • Modulating Heat Highly precise system combines a modulating gas valve with variable speed technology to deliver consistent temperatures while saving energy. It constantly varies heat and airflow in increments as small as 5%' responding to outdoor conditions and household comfort needs. By comparison' a typical single-stage furnace operates at full heating capacity every time it cycles on.
  • Quiet Combustion Technology Uses a smaller Btu input per burner for quieter start-up and operation while providing more even heat distribution.
  • Variable Speed Blower By changing the speed of airflow' your furnace can adjust humidity levels and create more even temperatures throughout your home' while enhancing efficiency and reducing operating noise.
  • Internal Monitoring Your Armstrong Air A97MV furnace’s 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.
  • Comfort Sync-Enabled Control Board For added peace of mind' your Armstrong Air A962V can continuously monitor internal components for optimum performance and fault prevention. It can even work together with your Comfort Sync thermostat to notify you and your dealer if repair or maintenance is needed.
