A Continental gas furnace is one of the most stylish and efficient furnaces on the market. Continental’s two-stage furnace reduces temperature swings within your home, maintaining a consistent and comfortable temperature. The furnace will operate on low fire for greater efficiency and comfort for most of the heating season. On colder days, the furnace automatically switches to the second stage, producing more heat to satisfy demand. This effective two-stage system is like having two furnaces in one. You’ll be warm all winter long.
