The next Generation of gas furnaces
Introducing the Lennox® G71P
“The quietest furnace that you can buy* – and one of the most efficient!
Featuring new Precise Comfort™ and AirFlex™ Technologies

There’s no place like your home, especially when the air inside suits your comfort level. The new G71P uses innovative Precise Comfort™ technology to create a living space with just the right amount of heat, regardless of the temperature outside.
“The quietest furnace that you can buy* – and one of the most efficient!
Advanced technology that enhances your comfort also improves sound performance and energy efficiency. The G71P is up to eight times quieter than competitive models. And, with an energy rating of 95% AFUE, it can save you up to $1000.00 each year on your utility bills.
* Based on sound pressure levels during steady-state, high-fire operation of Lennox
G71P-36B-070 and leading competitive units at mid-point temperature rise
and minimal static pressure when set up per section 4.5.3 of ARI 260.
Precise Comfort™ technology
Thanks to new technological advancements, the G71P constantly monitor and automatically adjusts fan speed, heat and airflow capacity demands to match the space requirements of your home – without over-conditioning or wasting energy. It goes beyond typical low and high two-stage operation, varying output from 40% to 100% in increments as small as 1%. Because the G71P is so precise, your home stays perfectly comfortable on milder days, the coldest days and every day in between.

AirFlex™ Technology
The G71’s innovative AirFlex™ Technology allows our installers 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 air flow, or to combine functions as needed. When paired with a Lennox® air conditioner of heat pump, the G71P is able to provide customized comfort from the outdoor cold winter to the extremes of summertime weather.
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 variable speed motors use up to two-thirds less electricity that a standard single-speed motor, which means that it can significantly reduce your energy costs. You may also qualify for additional energy rebates.
DuAlFuel
The G71P offers even greater system efficiency when paired with an electric heat pump. Called dual fuel, this combination controls heating costs by seamlessly alternating between energy sources, depending on outdoor conditions and prevailing energy costs.

Improved air quality
When you set your thermostat to “FAN,” the G71P continues to slowly circulate air throughout your home resulting in two-thirds less energy cost than a traditional blower motor. That means you can run the fan constantly without significantly increasing operating costs. It also means better indoor air quality – low speed fan operation increases the effectiveness of your filters, allowing them to capture and remove more contaminants.
