C97 Series Two-Stage

The Highest Efficiency Two-Stage Furnace On The Market. 97% + AFUE translates into significantly lower fuel bills.



The C97 Tech Pro Series features a two-stage gas valve and a variable speed energy efficient ECM Eon blower motor. Continental’s two-stage furnace reduces temperature swings within your home, maintaining a consistent and comfortable temperature. The C97 Tech Pro furnace will operate on low fire for greater efficiency and comfort for most of the heating season.

With the C97 Tech Pro, you’ll be warm all winter long.
