Rated 4.5 out of 5 by 31 reviewers.
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
