MAXIMUM EFFICIENCY
The G71P delivers a highly-efficient
95% AFUE. Think of it this way: a
standard furnace operates like a car
in stop-and-go traffic–it's either
moving or sitting still, and burning
lots of fuel in the process. The G71P
operates more like highway driving
with the cruise control on, making
slight adjustments that allow
maximum fuel efficiency.
The G71P's variable speed motors
use up to two-thirds less electricity
than a standard single-speed motor,
too, which means it can significantly
reduce your energy costs. You may
also qualify for utility rebates.***
MINIMUM SOUND
The G71P furnace is much quieter
than other furnaces. Its variable
speed motor ramps up and
down slowly, so there’s no
sudden blast of air at startup.
And a specially insulated cabinet,
featuring patented noise-reducing
construction and SilentComfort™
technology, further reduces
operating sound to an
industry-leading low level.

AIRFLEX
™
TECHNOLOGY
A blower setting for
every region
The G71P’s innovative AirFlex
™
technology allows your Lennox
dealer to select the airside
performance best suited to your
lifestyle, home design and
geographic location.
Settings can be chosen to minimize
sound, reduce humidity, provide
increased airflow, or to combine
functions as needed. When paired
with a Lennox
®
air conditioner or
heat pump, the G71P is able to
provide customized comfort from
the outdoor cold of winter to the
extremes of summertime conditions.
This chart depicts potential energy savings you can
expect from the G71P furnace, versus older furnaces
with lower efficiency ratings. Criteria used in this
example are 2,000 full-load heating hours, with a
60,000 Btuh heating design load and $1.281 ccf for
gas. Your actual savings may vary, depending on the
weather patterns in your local area, local fuel rates
and your individual lifestyle.
