4HP16LT Two Stage Heat Pumps

Many heat pumps operate only at full power' but the Ducane 4HP16 has two different stages of heating and cooling. During mild weather' the two-stage compressor runs mostly at low capacity' using less energy. Longer' slower operating cycles also allow for more even temperatures' quieter operation and better humidity control.

  • Up to 16 SEER and 8.5 HSPF ratings
  • Two-stage compressor runs at a lower speed most of the time to keep you comfortable all year long' while reducing energy costs' humidity and sound levels
  • Heavy-duty compressor sound blanket lowers operating noise' so you can enjoy peace and quiet
  • Quiet Shift™ technology reduces operating sounds when the unit goes into defrost mode to remove frost and ice buildup' so you get better performance with minimal noise and less maintenance
  • Dual-Fuel system offers an ideal combination of energy sources' electric and gas' pairing a heat pump and matching gas furnace together to maintain comfort
  • Rigorous run-testing of each unit in our factory helps ensure the most reliable performance in your home
  • Comfort Alert 2 diagnostics factory installed
