During the testingprocess, they are subjected to temperatures that far exceednormal operating ranges, to ensure they will stand up todecades of use.EHX Technology:Every Armstrong Air furnace is engineered and built withEHX Technology, a patented design that eliminates the hotspots that can shorten furnace life. EHX Technology makesheat exchangers more durable, and with its advancedairflow system, more air contacts the heat exchangersurface area for greater heat transfer into the home,enhancing efficiency and comfort.Modulating Gas ValveHighly precise system combines a modulating gas valvewith variable-speed technology** to deliver consistenttemperatures while saving energy. It constantly variesheat and airflow in increments as small as 5%, respondingto outdoor conditions and household comfort needs. Bycomparison, a typical single-stage furnace operates atfull heating capacity every time it cycles on.Noise Reduction:Model shown A97MVInsulated cabinet prevents loss of warm air, while reducingnoise from the motor.Quiet Combustion Technology:Uses a lower Btu input per burner ensures quieter s tart-upand operation.Comfort Sync Control Panel:All Pro Series units continuously monitor internal componentsfor optimum performance and fault prevention.
