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 and warm I am unable to tell when it is running.temp. Stays exactly the same. December 5, 2012
Rated 5 out of 5 by Nice to have the best available energy efficient furnace. Just replaced a furnace that lasted fifty years in my house and hope to get great energy efficiency from this hi-tech furnace. Looking forward to the better use of my energy dollar. December 5, 2012
Rated 5 out of 5 by Excellent furnace This furnace is amazing - we previously had a cold house and this furnace keeps the whole house constantly warm and is VERY, VERY quiet! Had we known a new furnace could change our house as much as this furnace has, we would have upgraded long ago. December 5, 2012
Rated 5 out of 5 by Excellent features The SLP98V was the best choice for our requirements, replacing the original 22 year old builder grade system. The house now has a general warmer feel to it overall, the system is very quiet and extremely efficient. I look forward to a continued lowering of my energy costs, and the touch thermostat provides fingertip controls of many functions, reminders, and services. December 4, 2012
Rated 5 out of 5 by Quiet, efficient, warm = happy homeowners. This is a quiet, quiet, quiet furnace. We rarely even know it is on. It quickly and efficiently modulates our home temperature precisely, saving energy when we are away, and keeping us warm when we are home. We are very happy we chose this furnace. December 3, 2012
Rated 2 out of 5 by This product is not for me I do not like it at all no air volume. The thing does not put out enough air to keep the basement in the house warm. December 2, 2012
Rated 5 out of 5 by This product has great features Kind of too soon to tell, but so far so good. The furnace is quiet and is distributing the heat more evenly thoughout the house. December 2, 2012
Rated 5 out of 5 by Simply amazing product! We were blown away by the comfort the SLP98V brought to our home - it is like nothing we have ever experienced in any of the homes we have owned. The variable speed blower is so onubtrusive you don't even know that the furnace is running - ever! Although it has only been a month since installation, I am looking forward to many comfortable years with the furnace. Anxious to see if there are any energy savings and can't wait to fire up the XC21 in the Spring! December 1, 2012
Rated 5 out of 5 by Quiet and even heating For years I lived with inconsistent temperatures and a furnace that seemed to struggle when it ignited. I finally decided a new furnace was in order. This furnace is a dream. It provides consistent and even heating, and is so quiet I don't know it is on until I go by a duct and feel heat coming out. I know this furnace will serve me well in Michigan' winters for years to come. Thank you Lennox! December 1, 2012
Rated 5 out of 5 by Best on the market The product is everything the literature claims it to be. The best on the market and worth the cost. November 30, 2012
Rated 5 out of 5 by Excellent Furnace Although I have not had the opportunity to use the furnace during extremely cold weather, my initial impression are very favorable. The unit is extremely quite and the variable speed fan runs only at the speed needed to maintain room temperature at the specified thermostat setting. November 30, 2012
Rated 5 out of 5 by Very Quiet The furnace is located right next to our family room where we watch TV. It is so quiet that we can hardly hear it. We keep the temp set at 69 degrees and are toasty warm all the time. November 30, 2012
Rated 5 out of 5 by Amazingly quiet and efficient with fantastic features This unit is one fine piece of machinery. The dual heat feature is fantastic, it is quiet as a mouse, it heats my home quickly and more evenly, and our first full month's natural gas bill showed a 39% drop in fuel usage as compared to the same month last year ... with nearly equal average daily temps in both months. We could NOT BE MORE PLEASED and will HIGHLY recommend this unit and Lennox to anyone who mentions needing a new furnace. Thanks! November 30, 2012
Rated 5 out of 5 by This product is fantatstic It is unbelievably quiet. I never hear it come on. My house doesn't have any cool spots and the running the programs for the thermostat is easy November 29, 2012
Rated 5 out of 5 by Even heating room to room The temp varience from room to room is within one degree very quiet unit November 29, 2012
Rated 5 out of 5 by Operates as adveristed and better! Great system that keeps the home warm at lower temperature settings than previous furnace. I would recommend this furnace, if for no other reason, because of the smaller utility room footprint, the quiet fan and the constant operation of the efficient DC motor-drivern circulating fan. Purchsed the WIFI Thermostat and it is a breeze to access and oiperate remotely. November 29, 2012
Rated 5 out of 5 by This product has fully met my expectations. The Signature series modulating gas valve furnace is a perfect match for my 1950's bungalow and Canada's cold winters. With the older homes and poorer insulation techniques, I feel it is neccesary to have the right furnace to meet your needs. The modulating gas valve is able to adjust and compensate to meet the heating needs effectively. It provides consistent and even heat distribution in my house no matter what the weather is outside. The furnace is so amazingly quiet, you often wonder if it is even running. November 29, 2012
