Rated 5 out of 5 by Happy Customer We recently had the Lennox Furnace installed in the dead of winter to replace a 15 year old furnace that was too big for the house. The furnace now runs for less time, keeps the house warmer, and has made a dent in our heating bill. The wife is happy, and a happy wife = happy husband/customer! Also, the Reason for Replacement is really between Planned and Emergency. We planned two months out when we identified our problem with the furnace, so we had time to shop and compare. March 12, 2013
Rated 5 out of 5 by value and performance Unit fit right in where I needed, in may attic. Easily adapted to existing ductwork. It is performing like a champ. Saved energy too, natural gas. Quiet except for a little extra vent noise from improved air flow. Mounts in the position I needed since I had limited space. Time will tell if it lasts 31 years without service like my last Lennox unit did! Good value. So far, very happy! March 12, 2013
Rated 5 out of 5 by This product has great features The furnace is very quit and has a powerful fan. It heats up the house quickly March 11, 2013
Rated 5 out of 5 by I selected this product because it has less bells & whistles that could go wrong. The main reason that I replaced my existing Lennox furnace with this model was because I did not want to core-drill a 4" diameter hole through my brick to vent a 90% efficiency unit. March 11, 2013
Rated 4 out of 5 by Keeps me warm. My new Lennox furnace replaced an existing Lennox unit which was twenty-one years old. The new unit has a stronger motor, blowing more hot air through my home. It keeps up with my 4,600 square foot home nicely. Toasty is what I would say when asked how my home feels now, although the reason we replaced the old unit was because the companion a/c unit was dying. March 5, 2013

Rated 5 out of 5 by affordable great furnace This furnace is 100% better than my old one it really does heat the house much better and is much more quiet and it runs less so that means im saving money! February 21, 2013
Rated 5 out of 5 by Great value. Furnace runs reasonably quiet. Heats well. Efficient for the price. February 20, 2013
Rated 4 out of 5 by Furnace is quiet Am surprised at how often the furnace runs and the short amount of time it runs. Am concerned that this will shorten life of furnace. My previous furnace was 27 years old and still running but needed to upgrade for selling. I live in an average sized townhouse so did not need high efficiency furnace. Hard to determine if new Lennox furnace is more efficient with how often it runs. Thought I'd be able to notice a difference since my old furnace was so old. February 15, 2013
Rated 5 out of 5 by Very economical to purchase and solid value We were looking for a furnace that was affordable to purchase, and with a solid company behind it. We have been extremely pleased with Lennox, and with our Lennox dealer. They stand behind the product. Yes, you can get a higher efficiency unit but if you are on a tight budget, this furnace is great. February 12, 2013

Rated 5 out of 5 by This product works better than advertised. Heater provides great air flow, is quiet, and heats my home efficiently. My heating bill was considerably lower the first month it was in use. There are no cold rooms in our home, now. The basement rooms were difficult to keep heated, but we have had no such problem since this unit was installed. January 27, 2013
Rated 5 out of 5 by I don't even think about it....my family is just comfortable. During the day, its 68 degrees F. At night, its a comfortable 65. We can't hardly hear our furnace run. we wish we would've got our new system years earlier. January 24, 2013
Rated 4 out of 5 by Improved efficiency over my old one. It operates quietly and puts out steady air flow. It quickly makes the room comfortably warm and it maintains a steady temperature. January 24, 2013
Rated 5 out of 5 by very quiet compared to previous unit !!! I did not have time to compare other furnance prices as my furnance was old and quit at the end of january and it was very cold outside!! I would have liked to shop around but was unable to do so. However i thought the person that looked at furnance was honest did the right thing !! January 23, 2013
Rated 4 out of 5 by This furnace heats well. The furnace has a powerful blower, but it is quite noisy. As an entry level model, i suppose this is to be expected as one of the price tradeoffs. January 5, 2013
Rated 5 out of 5 by Quiet furnace, more efficient than old unit As expected, the new ML180 is more efficient than our old 28 year old model, but is also much quieter which is a great benefit since our furnace intake is by the front door and near our family/living rooms. The new Lenox furnace is much quieter which means we don't mind it running like the old furnace. The new one is also showing to be more energy efficient after the first couple months power bills, but time will tell through the winter how much better it will be. December 26, 2012
Rated 5 out of 5 This product is quiet and effective This product works very quietly. Our bedroom is right under the Furnace in the attic and we forget the furnace is on because we can't hear it working. This product is also very effective. It takes only a few minutes for our entire home to heat up several degrees. This product would be 100% complete for us (we work from home and our kids/babies stay home the entire time) if it had more than 4 settings to set different temperatures. 6 different settings would be ideal.

Rated 5 out of 5 by Old Lennox durability My last Lennox lasted 48 years requiring only a new blower motor and a few thermo-couple replacements. Hope this one does the same. Blower makes slightly more noise but does blow stronger. Blower fan speed could be reduced but gets heat to the longer runs better this way. Very satisified. December 22, 2012
Rated 4 out of 5 by Small unit, fits well in tight places. Only been three weeks so it's really to soon to comment. Heats up fast. Strong volume of air coming out the ducts. Unit is installed in a closet inside my condo. Have to turn the volume up on my tv when the unit turns on. Good thing it doesn't run much. December 19, 2012
Rated 5 out of 5 by Quiet and effiecient Unit seems very quiet and effiecient. Smaller size than my older unit, takes up less space. December 18, 2012
Rated 4 out of 5 by Unit has improved efficiency and will save operating costs. Unit was installed quickly and efficiently by technicians. Features and functions are simple to understand. Expect efficient operation over many years to come. December 12, 2012
Rated 5 out of 5 by Great performance and efficiency This furnace replaced one that was 22 years old. It is quiet and efficient. My heating bill has dropped since it has been installed. December 8, 2012
Rated 4 out of 5 by fit my needs needed a special purpose fit, this unit did the job December 5, 2012
Rated 5 out of 5 by This product has great features. Product is concise in size which doesn't take up as much space as previous model. The quietness of operation is outstanding. I highly recommend this product to all. December 4, 2012
Rated 4 out of 5 by Good features for budget price We chose this furnace as we didn't want the extra expense of the high efficiency machine and the new holes in the wall for the PVC exhaust. Since we may not be in this house for more than 5 years, the savings in money outweighed energy savings. So far it seems to be a good machine, but the blower is a bit louder than the one we replaced.

Rated 5 out of 5 by This product is great! This furnace is so quiet, and puts out alot of heat. November 27, 2012
Rated 5 out of 5 by It fit into the same location as my old furnace the furnace was installed and placed into service in less than 3 hours. the installers knew what they were doing and did it well. I like the looks of the furnace, and the installers made it look like it was meant for the location that they put it into. I like the 2 speed blower feature. It was an upgrade of the removed furnace that functioned very well for 22 years. November 24, 2012
Rated 5 out of 5 by great features Quiet, efficient and small enough to fit in a small place November 8, 2012
