G61 Gas Furnace
Two-stage, high-efficiency heating
Two levels of heating allow you to enjoy higher levels of comfort and efficiency. Unlike typical single-stage furnaces that operate at only one speed—full capacity—the G61 adjusts heating output to keep you warm, while reducing your energy costs.
Here are some of the top features of the G61:
Efficiency rating of up to 95% AFUE can save you hundreds of dollars each year*, compared to standard furnaces.
Two-stage operation runs at low speed 80% of the time, minimizing the up-and-down temperature changes associated with standard furnaces.

Rated 5 out of 5 by Dependable Great updated Furnace. I have had this unit for more than 3 years now, and it has performed flawlessly. Very efficient and quiet. Installed an air cleaner and humidifier at the same time. I would definitely purchase another Lennox product again in the future. April 12, 2013

Rated 5 out of 5 by Charles great features So far so good! We just had the furnace installed a few weeks ago and are curious how it will affect our gas bill. We were pleasantly surprised that it came with a programmable thermostat, which was a big plus, to conserve more energy. February 6, 2013
Rated 5 out of 5 by Sam2709 This is a great product We had the first high efficiency furnace that Lennox made back in 1988. We had it serviced every year and were very satisfied with it. Since parts are no longer available we had to purchase a new furnace just this past month, when a problem developed that could not be fixed without parts. We are very satisfied so far with this new furnace. We also purchased an accompanying air filter and humidifier system. With this winter's extremes in temperatures this furnace system is noticibly better than our old one. January 28, 2013
Rated 3 out of 5 Furnace has had two failures in 2 years One month after I bought it, the combustion air blower failed and 18 months after I bought it, the rollout switch kept tripping resulting in no heat. It's a fairly basic furnace so I'm not sure why it would break so often. January 23, 2013
Rated 5 out of 5 by missymac Our gas consumption reduced by at least 35%. The install experience was very favorable. The furnace has met all our expectations and has reduced our gas consumption by about 35%. January 16, 2013
*This chart depicts potential energy savings you can expect from the G61 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.
