Rated 3 out of 5 by Supposed to be the best Upgraded from a 20 year old lennox only to discover the old furnace seemed to heat more efficiently. We used to set the temp at 68 and that was warm. Now we need to set at 72 and that still seems cold sometimes. January 22, 2013
Rated 5 out of 5 by Golden This has made 2 of my bedrooms warm in the winter that were always cold in the winter. It is QUIET also. January 21, 2013
Rated 5 out of 5 by In a word: quiet. We went from a very basic Lennox installed nearly ten years ago to the SLP98UH. Sometimes the old furnace would wake me at night when it started. With the SLP98UH I cannot tell when it turns on. At most, if I work at it, I notice variations in the rate of air flow out of the vents. But that's it. I know it is working because I'm warm.

Rated 5 out of 5 by This product is very quiet The new furnace is neat and compact, replacing a much larger unit so I now have added space in my utility room. The furnace is also very quiet and the thermostat system provided is very user friendly. January 8, 2013
Rated 4 out of 5 by Lennox Signature Series SLP98UH070V36B This furnace has great features, primarily as it is being used in a small home, it lives up to its marketing - it is quiet. Because it is quiet, it can run overnight and heats the home at a steady temperature that does not feel like a furnace is running so the focus is not about the season and the need for heat.

Rated 5 out of 5 by Awesome! My old furnace had a single speed blower, and the house always had hot and cold spots. With my new Lennox, I leave the fan on all the time as it slows down when heating/cooling isn't needed. The temperature is even, everywhere, all the time, and my basement is livable again!

Rated 5 out of 5 by Features, Efficiency & Reputation, then quiet I compared features & efficiency of the furnce brands commonly installed in our area and manufacturer product reliability ratings on Consumer Reports. Thankfully, availability was good, and had new furnace working in 3 days. I loved the variable capacity nature of the gas valve and really do appreciate the quietness during lower demand cycles. January 5, 2013
Rated 5 out of 5 by Very quiet! We switched from an electric furnace/ heat pump to this unit. What a wonderful difference! The furnace is so quiet, we usually cannot even tell when it is on. The heat is even and extremely comfortable. We have not gotten a gas bill yet and have never had a gas furnace in the house, so I can't address the efficiency. January 5, 2013
Rated 5 out of 5 by Great product No problems at all, very quiet. Very Efficient, my propane tank % has barely moved in two months! :) I combined this unit with one of their XP17-030 heat pumps, the set up is awesome! January 5, 2013

Rated 5 out of 5 by Efficient, quiet & great performance After chilly winters with electric heat, I wanted a furnace that would keep the house cozy and warm, plus reduce my heating costs. This furnace does that, and it's so quiet. I couldn't be happier with this unit. December 30, 2012
Rated 5 out of 5 by What a Difference! We knew our 10 year-old contractor-grade furnace was under-featured, inefficient and obsolete, but we didn't expect such a difference! Rather than a full-power, but short and loud blast of hot air followed by a long period while the house slowly cooled until the next blast, our new Lennox 'idles' silently while a gentle breeze of warm air diffuses through each room. We can't tell when it is running other than by the thermostat and even when it is we have to hold our hand over the register to be sure, but it is! I was in the basement after startup and the house was about ten degrees below setpoint so I got to hear the Lennox ramp up ... the burners gradually increased their sound, the fan gradually increased speed and after about half an hour the setpoint was reached. Since then it has been warm and comfortable, but most of all ... quiet! December 29, 2012
Rated 5 out of 5 Excelllent Product For the price, you won't find a better furnace. We can't hear the furnace at all and we are already saving on our bills!! Would recommend this furnace to anyone considering upgrading to the highest effeciency furnace they can get. December 29, 2012

Rated 5 out of 5 by Our home is much more comfortable. The temperature is constant within 0.1 degree. We have been able to turn the thermostat down one degree and still feel more comfortable. The furnace so quiet we do not know it is running. The thermostat is very user friendly. December 29, 2012
