Two
stages offer more even, continuous comfort.
Most conventional furnaces heat your home with a
single "full-blast" speed. Not our Freedom
90 Two-Stage and Freedom 90 Comfort - R™ furnaces.
Two-stage heating virtually eliminates the discomfort
of temperature swings caused by short-cycling, which
is a situation common to single-stage furnaces.
With
two stages, the unit operates on the first stage
more than 80 percent of the time, delivering more
even, continuous heating. It switches to the high-heat
stage only when absolutely necessary. And while
the furnace may actually run longer, it ultimately
uses less energy than single-stage furnaces. |
