Rated 5 out of 5 by This heat pump is energy star rated Our new Lennox heat pump has exceeded our expectations. It is quiet and has lowered our electric bill. April 2, 2014
Rated 2 out of 5 by Wouldn't recommend this system for a dog house. Purch. 2/13/14. Worked great until 3/1/14. Wouldn't hold temp. Sat - had to wait till Mon. 3/3. Was bad heat strip on heat unit & replaced. Worked great till 3/8/14. Again heat dropped. 38 degrees outside. Aux.heat began to fail. Compressor iced over like a giant ice cube. Now on emergency heat & dropping. Waiting for Mon. 3/10/14. Will be 2 service calls in 18 days. Very disgusted. March 9, 2014
Rated 4 out of 5 by Produces great air flow have had the 14HPX until installed since Dec 2012. I had heat on during our coldest months of winter and worked great under pressure of freezing temps. Now it’s summer and we are under high 30 ++ Celsius and the air conditioning works amazingly. Keeps the house at a normal livable temperature. We really like this unit July 15, 2013
Rated 5 out of 5 by A Great Value This unit was a replacement for a 17 yo dual fuel system. The price was very competitive and the efficiency has been more than what we expected. The thermostat can be set at a lower point during the heating season and a higher point when cooling and yet still achieve whole house comfort. A good value for the investment. July 9, 2013
Rated 5 out of 5 by Great heat pump we replaced a 13 year old lennox with this one. it cools very well. my only complaint is when the compresor starts up it gets a little noisy, i still gave it five stars because that is minor June 6, 2013
Rated 5 out of 5 by Very happy with this unit. I was skeptical when our salesman said we only needed a 4 ton unit when the one we were replacing was a 5 ton. But when he went through the calculations with us (which the other salesmen didn't do) we decided to go ahead with the purchase, adding a whole-house filter and complete duct cleaning. We are very happy with our decision. The house is cool, the unit is quiet and the installation was excellent. I have recommended this unit to my neighbor. April 26, 2013
