Rated 5 out of 5 by Extremely quiet operation and even heat throughout the house. In the month since installation we have enjoyed even heat throughout our home and quiet operation of the two stage blower motor. We are happy thus far with our choice of this particular non-condensing furnace model. March 12, 2013
Rated 5 out of 5 by Great Unit I've only had this a few weeks but so far its great. Its much quieter than our old unit, and the increase tonnage of the blower really helps to warm the rooms quicker. The Variable Speed fan has it running for shorter durations as well. March 12, 2013
Rated 4 out of 5 by quiet heater and warms the house quickly only takes a few minutes to warm up the house several degrees once we get home and turn the system on, March 12, 2013
Rated 5 out of 5 by Delivers what's needed My 27 year old furnace heated the house, quietly, and slowwwwwly. The variable speed fan motor on this unit moved so much air on first-time start-up that the return-air ducts had a low roar for the first time ever. However the house went from cold to hot in record time and the return-air sound was never heard again as the variable speed smoothly and quietly continues to move and maintain the air temperature.

Rated 5 out of 5 by Variable Speed Furnace The full time, variable speed fan produces a more even heat with the jet engine blower effect, and without hot and cold spots. March 8, 2013
Rated 5 out of 5 by So far so good I had my system installed 3 months ago and the heater has been running great. Very quiet, the variable speed makes a big difference. February 26, 2013
Rated 5 out of 5 by perfect fit Replaced 30 year old propane furnace and A/C with Lennox. Unit was a perfect fit in the old space with very little duct work needing to be done. A huge difference in warmpth of the house, much more comfortable. The 2 stage burners and variable speed fan provide saving on both electric bill and propane bill. February 25, 2013

Rated 5 out of 5 by Great Furnace Works great, noticed a difference right away. Very quiet, and also I recommend the humidifier in the dryer climate of winter in the Midwest. February 20, 2013
Rated 5 out of 5 by A GREAT FURNACE! We got THIS furnace when the OTHER one/Dinosaur decided to RETIRE! However, it lasted for 25 YEARS~~NOT TOO BAD! The LENNOX is an EXTREMELY QUIET UNIT! We've noticed a REDUCTION in our gas bill! While it's true our house DOES need some additional insulation, Our LENNOX furnace appears to heat the house QUITE WELL!!!!!!! February 17, 2013
Rated 5 out of 5 by This product has met and exceeded our expectations! I was told that this furnace would be quiet, efficient and that it would control the humidity in our basement. Though that sounded good, I wasn't sure it would be quite as great as I was told. But it truly is very quiet, does not constantly cut on and off, provides heat quickly, and effectively maintains a good humidity level. We are very pleased! February 16, 2013
Rated 5 out of 5 by Love the features This is very quiet and efficient running gas furnace we are very satisfied with our purchase of this product February 16, 2013
Rated 4 out of 5 by Very quiet and consistent heat I have only had this furnace in service for a few weeks but it was very impressive right out of the box. It easily maintains the set temperature on low speed and it is almost silent. My initial impression is that this is well made and high quality equipment. February 13, 2013
Rated 5 out of 5 by So quiet Love our new furnace. Always knew that our old one was kind of noisy. It wasn't until my husband asked how the new one was running that I realized you can hardly hear it! Love that it is so quiet and I am hoping we will also see a reduction in our energy bill with this more efficient furnace. February 13, 2013

Rated 5 out of 5 by Good heat production This furnace has good heat production but it is not quiet like advertised. It sounds like a rocket ship is taking off in my basement. February 10, 2013
Rated 5 out of 5 by What a difference! Boy, did I need this! My old furnace was located in a crawl space, extremely difficult to change the filter and without properly insulated duct work. This one is much quieter and much more efficient. February 10, 2013
Rated 5 out of 5 by So far....great! Very quiet operations....so far everything is great! February 6, 2013
Rated 5 out of 5 by Maintains even heat in the house This product was selected for its advanced features and because it did not require modifications to the house for its combustion exhaust. The variable speed fan is wonderful, and it allows us to use a lower speed to provide continuous circulation. February 6, 2013

Rated 5 out of 5 by This product really meets our unique needs. We have a two story house with a full finished basement. It was important to find a unit that would balance the heat between floors. We feel this unit really lives up to that reputation. January 28, 2013

Rated 5 out of 5 by This furnace has reduced my gas bill from the start. The unit is very quiet and efficient. I hardly know when it is running because it is so quiet. My first gas bill showed that it was an average of three degrees cooler in Dcember 2012 than it was in December 2011 yet I only used 3.4 therms in 2012 compared to 4.3 therms in 2011. I am extremely satisfied with this product. January 12, 2013
