Air Ease A97DSMV Series Comfort Sync Control

Air Ease A97DSMV Series Comfort Sync Control
Features:
  • Modulating Heat - Provides superior comfort over traditional single- stage and two-stage products, further reducing temperature swings in your home
  • Variable speed Fan Motor - By changing the speed of its airflow during start-up, your furnace can adjust humidity levels and create more even temperatures throughout your home, while enhancing efficiency and reducing operating noise.
  • Quiet Combustion Technology - Uses a smaller Btu input per burner for quieter start-up and operation while providing more even heat distribution.
  • EHX technology - Armstrong Air’s proprietary heat exchanger design is made of stainless steel for corrosion resistance and maximum strength against thermal fatigue caused by repeated heating and cooling. Advanced airflow properties eliminate hot spots and distribute heat more evenly than conventional designs. All these combine to extend the life of the heat exchanger.
