Rated 4.5 out of 5 by 37 reviewers.
Rated 5 out of 5 by So quiet and comfortable With our old unit, I would be jolted out of my chair on our screened porch when it would 'kick on'. This unit is so quiet I don't know it is running. August 14, 2014
Rated 5 out of 5 by Product has great performance. This Lennox product is performing way beyond what I had hoped for. With my old unit with the thermostat set at 78 it was still hotter than that all the time. With this new Lennox unit I actually have to push the thermostat up because the house stays so cool. I am very pleased with the performance of this product and would recommend the Lennox products to anyone. August 13, 2014
Rated 5 out of 5 by great unit great unit, smooth and quiet running. claim to be very efficient. August 12, 2014
Rated 5 out of 5 by Good Cooling Units We purchased two of these systems as replacements for old R22 equipment. Both are running great so far. They are quieter than our old units. They provide good cooling during the summer. We are anxious to see how they perform during the winter. August 12, 2014
Rated 5 out of 5 by So far, so good We have been happy so far with our new heat pump, which was installed on June 11 (about 7 1/2 weeks ago). It does an excellent job cooling the downstairs area of our home efficiently. Our first cooling bill was about $25 lower than this time last year, a little over 10% savings. It doesn't have a whole lot of bells and whistles, but I'm not convinced they're necessary. We live in South Texas, where it can get very hot in the summer, but our winters are extremely temperate. It is cooling great in the summer, so I anticipate it will heat well in the winter also. August 4, 2014
Rated 4 out of 5 by Responsible features We know this new Lennox heat pump will last us for a while. The name alone tells it is a good product. Love the new digital thermostat..easy to use July 21, 2014
Rated 5 out of 5 by This product does a great job We recently had the 14HPX heat pump system installed in our home. What a difference. Our previous system was installed when home was built in 2003 and it wasn't very effecient. Within a few hours after the installation, our home was so cool I couldn't believe. It really gets hot in this part of Texas this time of year and the heat pump is keeping our home very comfortable. Glad we chose Lennox. Hopefully the utility bills will improve as well.

Rated 5 out of 5 by Nice Balance Between Efficiency and Affordability When this unit is paired with the CBX27UH Air Handler it is able to achieve an SEER Rating of 15.....which is the magical efficiency rating which begins to qualify for an energy rebate in my area. Although not nearly as quiet as the Lennox variable speed models, this unit is much quieter than our old system. The unit seemed to fall nicely on the total cost of ownership grid with a nice balance between efficiency and affordability. July 7, 2014
