Rated 4 out of 5 by Runs like a champ My new Lennox gas furnace, model SLP98UH, is a replacement of a also new Lennox gas furnace, model G61MPV, that was only about four months old but failed constantly! The new furnace has functioned without the slightist problem and is a charmer. February 22, 2013
Rated 5 out of 5 by My home is evenly warm and cozy This furnace is quiet and efficient, and my home seems warmer all over without the hot spikes or cold moments. I especially appreciate how quiet it is. My old furnace was loud enough to wake me at night. February 21, 2013
Rated 4 out of 5 by good procuct So far this product is working fine. Hope it continues to work. February 20, 2013
Rated 5 out of 5 by Quiet! This furnace is so quiet we hardly ever hear it running! The house is kept at a constant temperature, there isn't any "chill feeling before the furnace comes on" that we had with our last one. February 20, 2013
Rated 5 out of 5 by Very quiet when running in lower stages. So far this unit has been great. Very quiet and runs in a low stage so the house stays evenly warm. My old heater make my house hot when it ran and then it got gradually cold until the unit kicked on again. Love the touch screen thermostat. February 19, 2013
Rated 5 out of 5 by One of the best purchases I've ever made You can't hear it, it is extremely efficient, and balances the air throughout the entire house effectively. When coupled with the iComfort Thermostat, you cannot go wrong. February 19, 2013
Rated 5 out of 5 by Helped even out the heat in our house Our house is not zoned and the continuously running fan and variable heat helped smooth out the unevenness from the previous furnace. It is very quiet and don't regret purchasing it for one second. February 18, 2013
Rated 5 out of 5 by Very quiet furnace I am very well satisfied with this furnace. It provides adequate heat and is very efficient and quiet running. February 18, 2013
Rated 5 out of 5 by This is like going from a Mule to a Rolls Royce!! My old furnace (~1985) was running at about 50-60% efficiency. My new Lennox furnace is running at 98% efficiency. Not only that, the WiFi thermostat is controllable remotely from my iPhone!! My house has no more cold rooms... the circulation feature works amazingly well!! I can't wait to get my first energy bill and see the savings, too! Thank you Lennox!! February 18, 2013
Rated 5 out of 5 by Great Heating product This heater is significantly better then the previous heater we own. Its able to heat the entire house and keep it at the comfort temperature the entire time. Our previous heater only heated the basement but the SLP98V was great at maintain the heat evenly throughout.

Rated 5 out of 5 by Light years ahead of the competition This is the most amazing furnace I've ever had. The features are outstanding, easy to operate. The reduction in noise is great, and I don't miss those huge rushes of blowing air. I have already made reccommendations to freinds. February 15, 2013
Rated 5 out of 5 by I replaced a 26 year old Lenox which had zero maintenance done. This model is so superior to the old one. Quiet and efficient. Keeps the temperature exactly where I set it ~ no 2 degrees under then kicks on until 2 degrees over. Maintains an even temperature. And extremely quiet. The slight cost over a lesser model is well worth the money spent. February 15, 2013
Rated 5 out of 5 by GREAT and efficient unit. Very happy! This unit is very efficient, energy saving and much smaller than our old unit. We are very happy with it! February 14, 2013
Rated 5 out of 5 by Nice features Like the quiet, gentle spool up. Also the variable speed for maintaining temperature rather than the full on-full off models. February 13, 2013
Rated 5 out of 5 by Great furnace so far Installed our furnace several weeks ago. Smooth sailing. The new furnace is very quiet. The variable heat and fan means that we no longer experience the rush of the heat turning on. The house is definitely more evenly heated and rooms that were often cold before are warmer now..heat seems to be more evenly distributed. We are very happy so far. Of course, it has only been a few weeks. I will try to update at some point in the future. February 12, 2013
Rated 5 out of 5 by Purchased due to reputation of Lennox I have only had the unt for 6 weeks and don't feel that is sufficient to make a proper judgement. Check with me after the winter is finished. So far, everything is functioning well and efficiently. I received my first bill, which was much lower than the electric furnace it replaced. February 12, 2013
Rated 5 out of 5 by Efficient quiet heater We are very happy with out new heater. The house is very warm and we can't hear the heater at all. Our previous heater was very loud. We've already seen a difference in our heating bill. February 11, 2013
Rated 5 out of 5 by Very Quite Very impressed with how quite this unit is. We are also impressed with how uniform the temperature is in the home. February 11, 2013
Rated 5 out of 5 by Quiet and energy efficient This furnace is so quiet that without the click of the thermostat one wouldn't even know it was running. It no longer wakes me up at night, my daughter has stopped complaining about her bedroom being cold and there is less dust. Our first gas bill was significantly lower even though our previous furnace was already a high efficiency unit and last year's winter was much warmer. February 10, 2013
Rated 5 out of 5 by Very happy with the performance of the system. The system is very quiet, energy efficient and the design is durable. February 10, 2013
Rated 5 out of 5 by quiet comfortable heat very quiet operation nice temperature control through out the entire house highly recommend February 8, 2013
Rated 5 out of 5 by Glad we went with the 98% variable furnace. We have been very pleased with our furnace! At first I was concerned about getting technology that is so new & cutting edge. But am i ever glad i listened to my husband (this time!) and went along with buying the 98% variable furnace! It has made a huge difference in the comfort in our home. We run the fan all the time and there are no more cold pockets of space in the house. In fact, my kids ended up taking a layer of blankets off their bed after the 1st few nights because it was so much warmer in their rooms than it was with our old furnace. Another thing that I am so happy with is how quiet it is. No more jets firing and sounding like a plane is taking off in our house! We are very happy and warm now! February 8, 2013
Rated 5 out of 5 This is an amazing product. This is an amazing product. I didn't realize how outdated my old furnace was. It's so quiet and the heat is HOT! We keep it set on 68 during the day and are very comfortable. The new thermostat is very easy to read and set. The total cost was way below quotes I got for other manufacturers 95% efficient units. I am very pleased. February 8, 2013
Rated 5 out of 5 by operation this furnace is so quiet i can barely hear it when i'm in the basement and the savings on electricty and gas were showing up in the first month and the savings were so great i think this furnace will pay for it self in 3 to 4 years not including adding value to my house. February 6, 2013
Rated 5 out of 5 by Overall, excellent product. We originally had a Lennox pulse furnace and wanted to replace it with a new model. We are pleased with its quiet, efficient performance. All levels of our home are comfortable at an even temperature. February 4, 2013
Rated 5 out of 5 by 100% change from prior furnace-it's great! The people, product and installation could not be better. It's so quiet i cannot tell when it's running. Thermostate is amazing. February 4, 2013
Rated 5 out of 5 by Very good. I am very pleased with my new furnace. It is extremely quiet and the heat is very even and comfortable. February 4, 2013
Rated 4 out of 5 by Quietest furnace I ever had I am impressed by the overall quality and quietness of the unit. I replaced a 22 year old unit and am amazed by the difference. Gas and electric bills are down over a three year average and I don't have to turn up to volume of the TV to override the noise of the previous unit. February 3, 2013
Rated 5 out of 5 by The furnace is very quiet and seems to provide an even distribution of heat. The furnace is very quiet and most of the time you do not even realize that it is running. The icomfort thermostat works well in tandem with the furnace allowing you to set daily programs and even program it remotely from a smart phone or computer. The variable speed works much better than our previous single stage model which turned on and off constantly. I would recommend this unit to anyone who is looking for efficient warmth, comfort and quiet operation. The Lennox brand continues to match or surpass its perceived value. Thank you for reading this review. February 2, 2013
Rated 5 out of 5 by Warm air from start to finish. I had a heat pump before and it started out blowing cold air and ended it's cycle blowing cold air which is not was you want in the Winter. I love this new heater. February 1, 2013
