2 Stage vs. 2 Stage w/ D.C. Motor

Pro's of a Two Stage Gas Furnace

• Much quieter than a Single Stage Furnace.
• 2 heat capacities (Low stage and High stage).
• Fan Motor is quieter than a single stage as it is running at a lower speed.
• The decreased heat capacity on low stage enables the furnace to run longer which is more efficient.
• Cold spots are virtually eliminated, as there is a much more even temperature when the furnace runs longer cycles.
• The furnace will run at low stage for the better part of the heating season, ensuring quiet, even heating.

Pro's of a Two Stage Gas Furnace with DC Motor

• The quietest furnace available.
• Even quieter than the two stage furnace.
• The fan motor blowing the air is constantly variable according to the heat input.
• The fan motor is direct current (D.C) instead of alternating current (A.C).
• If your fan is run continuously, your electrical savings can be substantial.
• Electrical savings currently may be approximately $ 450 + per year, over its alternating current (A.C) counterpart.
