Rated 5 out of 5 by Great product! We especially love the energy savings and the wifi capabilities of the thermostat. December 27, 2012
Rated 5 out of 5 by super quiet Here in Central Valley California we don't need that much heat. Our old furnace would come on for 5 minutes and sound like a jet engine, and shut off. The installers enlarged some ducts, and installed our new furnace. Because it comes on at less than half capacity, most of the time we don't even hear it running, it just keeps us comfortable.

Rated 5 out of 5 by Excellent Product Quiet and extremely efficient. Very pleased on all aspects with our purchase of this product. December 27, 2012
Rated 5 out of 5 by Very pleased with the variable speeds this furnace runs at. This product provides a highly efficient variable capacity system that is quiet and energy saving. December 26, 2012
Rated 4 out of 5 by Advertised as High efficient unit The unit is quiet running and does a good job of maintaining the temperature in the living area. While it was just installed this month I can not comment on the savings at this point. So far I have been very satisfied with the unit. The only issue is I feel it is higher priced than competitors comparing simular units. December 25, 2012
Rated 5 out of 5 by quiet great efficiency and excellent features consistant temp from top floor to basement excellent furnace and wifi thermostat easy to use. December 24, 2012
Rated 5 out of 5 by Great furnace I am totally impressed with how quiet this furnace is compared to my last Lennox high efficiency furnace (21 years old). December 24, 2012
Rated 5 out of 5 by This product is so quiet that you cannot hear it . This product is truly impressive in how quiet it is . The product delivers what is said about it by Lennox. My family could not beieve how quiet it is and stll delivers the heat efficiently. I look forward to many years of quiet operation in the delivery of heat to my home. December 24, 2012
Rated 5 out of 5 by This product exactly what it is advertised to do. Have only had this product just over a month and I am extremely satisfied with it it. The even heating and especially the quietness are very nice. I am looking forward trying the new A/C this summer. Five stars as far as I'm concerned. December 24, 2012
Rated 5 out of 5 by this heater is quiet and efficient. I am happy with my purchase; I no longer feel changes in temperature between heat cycles. It is very quiet and I expect my bill to be considerably lower. December 23, 2012
Rated 5 out of 5 by Quiet and efficient!!! The furnace is very quiet. You hardly know it is running. It keeps the temperature very level - where you set it. It does not heat the house and let it cool in a cycle like older, more nornal furnaces. Our natural gas bills are noticeably lower too. Great product and great value for the price. December 22, 2012
Rated 1 out of 5 by 6 service calls in the first 2 years We bought a Lennox SLP98UH series variable capacity gas furnace November 2011. Less than a week later, it stopped working. In only the two half-winters that we have had this furnace (the latter half of 2011 winter and the first half of the 2012 winter) we have had 6 service calls for having no heating. This was the top of the line Lennox model, so it was very expensive. We are freezing and are not very happy. It's not working again today. December 21, 2012
Rated 5 out of 5 by Unbelievably quiet and efficient You need to be standing next to this unit to know it's running. The water heater next to the furnace is twice as loud when it's heating. WIFI connected color thermostat lets you check and control the system from anywhere on a smartphone or tablet. Add to that 98% efficiency made this decision easy. December 21, 2012
Rated 5 out of 5 by Just a GREAT product. I am very satisfied with the new furnace. It produces a smooth and even heat, and not the "hot" heat of my previous furnace. It is so quite, I do not even know it is on and working. December 21, 2012
Rated 5 out of 5 by Great overall product This furnace exceeded my expectations. The variable-speed motor provides a consistent temperature throughout the open concept main floor. The furnace is extremely quiet while maintaining constant air flow. Now I wish I would've installed a variable-capacity furnace in my basement instead of the single-stage. December 20, 2012
Rated 5 out of 5 by Very quite and eficient furance I have replaced this furance with my old 60% efficient furance. It is quite and keep the house warm by consuning less gas. We are enjoying this furance December 20, 2012
Rated 5 out of 5 by The furnace is consistent The furnace is so quiet. The heat in the entire home seems to be consistent and warmer. When it's colder outdoors, the furnace adjusts to those conditions and will run for a longer period to keep inside temperature consistent. The furnace is eneryefficient. December 20, 2012
Rated 4 out of 5 by We are satisfied! We were looking for the best product we could find at a reasonable price. It wasn't the cheapest but one gets what one pays for. With the savings with the efficiency it will pay for the difference in cost in a few years. It is very quiet and the technology is up-to-date. We are very satisfied so far and will look forward to the savings this first winter. December 19, 2012
Rated 4 out of 5 by Quiter than our old furnace! We have had this furnace for 1 week and we immediately noticed a difference in the temperature and comfort of our home. The modulating component is still a bit unclear to me, as the furnace seems to increase in capacity (i.e.. it gets louder) as it is running every time it comes on. I thought it would be running at 35% (for example) rather than ramping up. December 19, 2012
Rated 5 out of 5 by Runs very quietly. Since the furnace was installed two weeks ago we have noticed much more even heating throughout our house and it runs so quietly that often we are not even aware it is running. December 19, 2012
Rated 5 out of 5 by this product is keeping me warm. I love the humidifier on it along with the air cleaner I am finally comfortable in my home. It is large enough to take care of my whole house and keep all rooms warm. The added feature of a humidifier is great. I don't feel like I am in need of lotion all the time. Thank you December 18, 2012
Rated 5 out of 5 by This product is awsome ! This is the quietest furnace I have ever seen. I used to burn wood to help out my old furnace because there were cool spots in the house all over the place. this furmace is so good that I am going to quit burning wood even though I get the wood free. Also the fan blows so low that you don't even feel it. Thanks LENNOX . December 18, 2012
Rated 5 out of 5 by Great product, great job installing This furnace is so quiet you can't evern tell it is on. Nice even heat in the house. Thanks for a wonderful job. December 18, 2012
Rated 5 out of 5 by this furnace is compact and quiet This furnace replaced a noisy boiler and air-handler, the house was cold upstairs, and not very warm elsewhere. Now the house is evenly heated and the system is so quiet, I sometimes wonder if it is even on! December 17, 2012
Rated 5 out of 5 by Great product when looking for energy efficiency Have 2 units, one in the house and one in the hangar that heats the offices. Both are reliable and efficient. Faults codes work good at solving minor problems as when I repainted floor and raised the vapor return hose too off floor high causing too much back pressure and furnace wouldn't light. December 17, 2012
Rated 5 out of 5 by this product performs the way it is advetised, excellant. Very quiet, yet blows and exchanges more air than an older Lennox furnace. I like the quiet start period in the morning when the set back thermostat kicks in. How can you go wrong when you get a total labour and parts warrinty for ten years. This is the furnace of the future. December 17, 2012
Rated 5 out of 5 by Superb Furnace! This is the best furnace I have ever owned. The variable capacity is just perfect for the earth contact, energy efficient home into which it is installed! December 17, 2012
Rated 5 out of 5 by A modern marvel of comfort technology With the continuous low speed fan and high efficiency, this furnace has kept our house warmer feeling at a lower cost then our previous furnace. December 17, 2012
Rated 5 out of 5 by This furnace runs quietly and warms up the house beautifully. We should have done this years ago. It's quiet and warms up the house beautifully. Enjoy not having to remember to turn the thermostat down at night. December 15, 2012
Rated 5 out of 5 by Lovely and quiet, nice level heating It works just as the advert says, quiet, efficient and effective! December 15, 2012
