Rated 4.5 out of 5 by 37 reviewers.
Rated 5 out of 5 by Extremely quiet and powerful. This is a gorgeous machine, it is so quiet and powerful. We have two, 2-tonn units. We love the two speed compressor and the variable speed air blower. I think they will last 20 years and I will enjoy them the entire time, mostly because I can't hear them running. We have two outdoor units, just a meter or so apart and you just don't hear them. We love to relax on the back porch (after all I still enjoy the outdoors as well as a cool-dry house) and the two XP-16 compressors are just about 20 feet away from the porch, down the house along the rear wall of the house. We sit out there and rock on our large swing-bench and don't even notice the a/c sounds. I love the new programmable thermostats and I am able to program the upstairs sleeping quarters very differently than our downstairs living spaces. We have a Cape Cod style house with 3 bedrooms and 2 baths upstairs. Downstairs our house consists of the Kitchen, Breakfast room, Great-Room, Laundry, 1/2 bath, dry-stores pantry, and a large dining room that we have converted into an office. Thus you can see the living situation is very different upstairs verses downstairs and we program the 5-time zone thermostats very differently to match our lives. Super easy to control and very intuitive to adjust. Full flexibility for every day of the week, with 5 periods per day. We love the "Lennox" units! September 12, 2012
Rated 5 out of 5 by Helps keep 4-level split house comfortable No complaints so far with this heat pump; we've not had it through a cold Iowa winter (we have a backup lp furnace for supplemental heating), so hopefully it will work well all year round. Unit isn't too loud and seems to work well! September 12, 2014
Rated 5 out of 5 by Awesome, efficient Very sturdy and efficient. Great in the Florida heat. September 6, 2014
Rated 5 out of 5 by This product works great! We are very pleased with this unit. After installation the servicemen took a few minutes to show us what we needed to know. It is easy to understand and easy to set to our needs. This unit cools our home and with the programmable thermostat, we rarely even have to look at the controls to know that it is working the way we want it. Our sales person knew this product and knew it would do exctly what we were needing! August 30, 2014
Rated 4 out of 5 by Less electricity Too soon to tell but I'm sure it will use less electricity August 18, 2014
Rated 4 out of 5 by Great HVAC units questionable wifi thermostats In Dec 2012, I had 2-Lennox HVAC systems installed for each side of my home. This included 2-XP16 (2-stage Heat Pumps and 2-CBX32MV variable speed air handlers. So far, the units are quiet and perform efficiently. The problem was that I ordered 2-Icomfort 5000 wi-fi thermostats to control each system. These are beautiful thermostats, functional and easy to operate and to access over the internet. The problem is their reliability! After only 7 mos of use, one of the thermostats stopped working. I just turned 14mos on both systems and now the second thermostat to the other HVAC unit has stopped working? When this happens, you lose access to heat or cooling. I have other devices in home which use wi-fi without issue or device failure. I would like to work with Lennox to determine any defects because I believe in Lennox. In the immediate however, I’m online trying to find a more dependable set thermostats. This is too close in to the purchase of these expensive thermostats to be experiencing these issues. I recommend the HVAC units but find it difficult to recommend the Lennox Wi-Fi thermostats. February 22, 2014
Rated 1 out of 5 by Very poor quality We have only had this unit about 4 months. The outside unit was never coming on and unfortunately we never new that until the electric bills arrived. We assumed the unit was as quite as all the reviews had said which was one of our reasons for buying it. It has not lived up to our expectations. This is our third heat pump and the only brand we ever had to place a call for service and it is basically brand new. January 17, 2014
Rated 5 out of 5 by does its job well Cooling and humidity control are outstanding. Heat is efficient. It is quite quiet except at the end of a heat cycle. We have had it for 15 months.It has exceeded our expectations for two summers and a NE winter. August 25, 2013

*This chart compares the 5-year savings you can expect from a 16.50 SEER/9.50 HSPF heat pump vs. existing equipment with a 10.00 SEER/6.80 HSPF rating and industry-standard equipment with a 13.00 SEER/7.70 HSPF 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 650 cooling hours, 2,400 heating 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.
**Must be accompanied by either a variable speed air handler or furnace and the ComfortSense® 7000 Series touchscreen thermostat.
