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
Rated 5 out of 5 by Very quiet and efficient. I was forced into replacing our old furnace when it developed a cracked heat exchanger. Now that we have the SLP98V I realized that we should have replaced it years ago. December 14, 2012
Rated 5 out of 5 by excellent product really am impressed with this product. Had it installed with the icomfort thermostat. The changes in the comfort of the home is dramatic. Constant temperature and humidity rather than the constant temperature changes are really what we had wanted when we had this installed. Well, we got what we wanted. Easier to sleep. No cold spots. Would recommend this in a minute. December 13, 2012
Rated 5 out of 5 Love my new furnace I'm very pleased with my new furnace. The variable speed and other features make it quiet and efficient. I've found that the temperature in my house seems to be more even from room to room. December 12, 2012
Rated 5 out of 5 by This product is really what every household should have. This product is really quiet . Love it. I noticed that it helped me with my sleep in the night. Especially in a very cold night. Also we feel safe and don't have to worry about the gas leak. We haven't got our gas bill yet. I'm interested to see how much money it will save us. And we hope we can get our energy rebate soon. December 12, 2012
Rated 3 out of 5 by Very quiet This furnace is so quiet. It sounds like a refrigerator. Not sure if we like the heat source. It seems so much colder at same temperature as our old furnace. Hope to save money on gas bill. December 11, 2012
Rated 5 out of 5 by Great features, functionality, and efficiencies The new 3-zone system with the new furnace and new A/C with 98% efficiency and variable speed fan will finally allow me to properly control the temperature in my story-and-a-half home. December 11, 2012
Rated 5 out of 5 by Very quiet This unit is much more quieter than my old unit. Sometimes I can't even hear it operates. It is installed next to all the bed rooms. I can sleep without waking up during the night when the heating kicks on. Since I also did the home energy upgrades, so it is hard for me to tell how much energy I save with this new unit compares to the old unit. At first I worry the variable speed fan may not work well on low speed to have enough control for all the rooms. So far, it works fine with the icomfort. The fan motor does sound little louder when it turns on and turns off, but is still quiet. December 10, 2012
Rated 5 out of 5 by This units features work as advertised. this unit keeps our house at a very even temperature.It also has a quiet operation.I am very impressed with the variable capacity gas valve and the variable speed blower. December 10, 2012
Rated 5 out of 5 by Quiet So quiet compared to our old furnace. Very comfortable in the house now. December 6, 2012
