Reviews

Rated 4.8 out of 5 by 97 reviewers.
Rated 5 out of 5 by Great I never write reviews but in this case made an exception. We had to replace a 13 year old unit (a/c and heater). The outside unit was quite noisy and bothersome whenever it was running. As we were researching new units this Lennox model kept coming up for quietness and operation. In short, while it is expensive, it is an amazing unit and thus far has given us no problems (4 months into its use). It is whisper quiet. We almost went with a less expensive unit but we are glad we chose this one. October 3, 2013
Rated 5 out of 5 by This Air Conditioner Is Quiet and Effiient This air conditioning unit will cool my house and maintain it to whatever temperature I set. I couldn't be more pleased. July 16, 2014
Rated 5 out of 5 Very quite and lower operation cost I would never have believe that an a/c unit would be as quite and efficient as this unit is. July 15, 2014
Rated 5 out of 5 by Exceptional quality and value The entire system was installed in a day and we are now enjoying comfort and quiet we never knew existed. The whole house is fresher and more comfortable than ever, and the Wi-Fi touchpad together with smartphone app is really convenient. July 13, 2014
Rated 5 out of 5 by This unit has great features The unit is quiet, efficient (it dehumidifies before cooling), and we love the display and ease of use of the digital programmable thermostat (as well as i-control feature). July 13, 2014
Rated 5 out of 5 by Wonderful Features! I replaced my old Lennox with a newer efficient 2 stage Lennox. It is so quiet you can hardly hear it and it is so efficient that it cools the house off in no time! If there is an excess of humidity, it will take that out only. Love, love, love it! July 11, 2014
Rated 5 out of 5 by Shhhhhh! This thing has some serious cooling power! I couldn't believe how quiet and smooth this unit runs. Standing 15 feet away, I couldn't tell if it was running! I can hear the neighbor's A/C unit kick on on the other side of the house! lol I felt pretty good going with another Lennox A/C unit. The last one was installed 21 years ago! I wouldn't have replaced it if it wasn't for the coil drip pan rusting out! July 9, 2014
Rated 5 out of 5 by Quiet! They said it would be quiet but it is so quiet you can't tell when it's running. As suggested, we keep the fan on and can't even hear that. Installed in May, now July and the system is great (along with a Lennox variable speed 2 state gas furnace). July 7, 2014

*This chart compares the 5-year savings you can expect from a 21.20 SEER air conditioner vs. existing equipment with a 10.00 SEER rating and industry-standard equipment with a 13.00 SEER rating. The region used to calculate household fuel and utility costs reflect a cross-section of cities in the U.S. In addition to geography, cooling costs are based on 3-ton capacity specifications, with 1,800 cooling hours per year and 11.62 cents per KWh (Source: EIA National average electric rate-Rolling 12 months ending July 2009). Your actual costs will vary depending on the weather, local fuel rates, system settings and your personal lifestyle.
