Rated 5 out of 5 by Rexx High performance, quiet, efficient furnace The SLP98V is a highly efficient, quiet, high performance furnace. With a 98% efficiency rating for propane or natural gas is phenomenal. Converted from Oil heat to propane with a 18% increased efficiency rating not even factoring in the efficiency of the modulating system. Instaled a combination unit with heat pump and A/C for all season home comfort management. The dynamic thermostat monitor has multiple seasonal programs and times for personalized efficiency by home life. The thermostat even includes outside temperature, humidity and temperature settings. Highly recommend the combination units. November 16, 2012
Rated 5 out of 5 by Briton Seems to have met my expectations. Reasonably quite and functions as I expected. A highly efficient i Comfort thermostat is part of the system. The difference in price between this product and the next level is significant but this was partially offset by a larger rebate for this model. Seemingly, very good choice! November 29, 2013
Rated 5 out of 5 by teenickinsd The best purchase I have ever made! This is extremely quite,even heats my home!! I would recommend this to anyone interested in purchasing a furnace for there home. November 11, 2013
Rated 5 out of 5 by SCHeatWave100 WOW what a difference from the last unit Replaced the whole system that was 12 years old (not Lennox) with Dave Lennox Signature series. AC is the XC-21, furnace is the SLP98V matched to the icomfort wiFi touchscreen thermostat. The SLP98V is so quite I have to look at the thermostat to see if system is running. The variable speed and capacity is a great feature. The house stays at a more constant temp. The old system would come on and run at full capacity (very loud) and than cut off causing the temp to go up and down about 4 degrees. This unit keeps the house very comfortable all the time. Thanks Dave. November 6, 2013
Rated 5 out of 5 by senior65 Very quiet We updated our furnace because ours was very loud. The ratings for fuel consumption were good on this furnace. We are satisfied with the quietness, it sounds like water running. So far we are pleased. November 4, 2013
Rated 5 out of 5 by Greg63 This furnace is ultra quiet! Our home has never been more comfortable with a constant warm feeling! We feel like we are living in a different house! October 28, 2013
Rated 5 out of 5 by Jumbo Best furnace I've ever installed! Hello I'm a Lennox service tech of 18years, so please listen when I say this is the best furnace I've ever installed in my home! I'm blown away by how quite this furnace is. Over the years where ever I am I'm always listening to units coming on, going off, belt noise, air noise, burner noise, vibration noise and not just at work its in a store, over a friends house, at my folks house, in the doctors office, well you get the picture. I'm just so in tune to hvac equipment it's at times disturbing to me! Lol! I just have to say I can't tell when the unit is running! I actually have to be in the basement to hear the unit run. So far in my 100yr old home I've been very comfortable this heating season, and running the vari speed blower all the time gives more comfort to cold rooms without hearing or worse yet feeling the cool air blowing on you during off cycles. I removed my 20yr old 80 present furnace so I'm really looking forward to fuel savings this year. I'm like the shoe maker, I don't want to come home and work on this furnace. Don't get me wrong I love my job! I get to fix things all day and make my customers happy! That said I don't think I will have to worry much about this furnace! Great engineering, great product, hats off to Lennox! I will be letting my customers know about this furnace when it's time for replacement cause I can sell a product better after I've used it in my own home! October 20, 2013
Rated 5 out of 5 by Jon12345 very quiet I have some ringing in my ears but I sure could hear my old Lennox, this one really Quiet, at times I have to look at the thermostat to see if it is running. October 13, 2013

Criteria used in this example are 2,000 full-load heating hours, with a 60,000 Btuh heating design load and $1.368 ccf for gas.
