Rated 4.4 out of 5 by 28 reviewers.
Rated 5 out of 5 by so far so good The unfortunate demise of my old system required the replacement of my heat pump. The Lennox system was one of two that would fit the space in the attic as well as the existing air handler. The unit is cooling well but I haven't used the heat yet. September 23, 2014
Rated 5 out of 5 by Great Unit and Great Buy I definitely do not like spending thousands of dollars on home repairs. However, I can unequivocally say I have upgraded significantly. I am not an ac guy but can absolutely tell the difference from what I had to what I have now with this 13HPX heat pump. This unit is quiet and is rated a SEER 13 which is the minimum rating standard. However, going from a SEER 10 to this unit has substantially improved our home cooling. We haven't hit winter yet but I doubt there will be any problems. You can definitely try other units to get a better SEER rating but stick with the HPX line and not the just the XP. Again great buy for the price and how great it works. September 18, 2014

Rated 5 out of 5 by This product has many qualities and features. We are very pleased with our new Lennox 13HPX heat pump unit. Already, we are seeing a decrease in our electric bill.

Rated 5 out of 5 by Economical and quiet This Heat Pump has some great economy features. The thermostat allows you to set your cooling preferences while you are gone. It's so much quieter than our other unit and it seems to keep the house consistantly cooler when it shuts off than our previous unit. July 25, 2014

Rated 5 out of 5 by Satisfied so far Seems to work very well as an A/C unit. We will have to wait and see how it works as a heat pump. Seems a bit noisy, like it is vibrating in the fan area when in operation. July 2, 2014

Rated 1 out of 5 by No heat Heat pump does not work. The blower motor does not work. Dealer no longer handles Lennox. Can't get parts. He dropped Lennox because 0f all the problems they were having with Lennox heat pumps. October 13, 2013
Rated 5 out of 5 by Definitely buy!!!!!!! We've had this unit for years here in Canada winters are cold but this heat pump heated the upstairs very nicely it freezes up a lot but we turned the defrost interval to 30 and it helped definitely recommend June 23, 2013
Rated 1 out of 5 by Don't buy We are replacing due to a bud compressor in just under 6 years. Other companies give a ten year. Unit was noisy and froze up often. Shop around when building do not assume that they will put a quality product in, because they will get the cheapest junk they can. This is that junk! June 2, 2013

Rated 5 out of 5 by Completely satisfied with this product. We have had a Lennox heating and air conditioning unit for our house more than 19 years and have been completely satisfied with it. Now we have added a large sunroom to our house and have a Lennox heat pump to provide supplementary heat and air just for this room and it works great. March 25, 2013

Rated 4 out of 5 by Heat pumps are the greatest thing since sliced bread Heat pumps are the greatest thing since sliced bread. December 12, 2012
Rated 5 out of 5 by This heat pump is reliable We had a new Lenox installed for the upstairs a year ago in December. Since we were very pleased with the operation, efficiency and cost of that one it was a no brainer to go with Lenox again when we needed to replace the downstairs heat pump. December 5, 2012
Rated 5 out of 5 by Heat Pump Very efficient and keeps the house temperatures within range with very minimal emergency heating calls. November 28, 2012
Rated 5 out of 5 by Fills our needs We purchased the 13HXP for our terrace level, new home, which had never been fitted with hvac. Within a week we noticed an improvement in the air quality, the smell, of course the temp and even the humidity which we had controlled previously with a dehumidifier. We live in GA, this level has two sides of full windows and doors and never gets really hot or cold but still the air quality was not acceptable. We are quite satisfied with this unit. it did not qualify for any rebates or energy promos, but it fills our needs for a seldom-used space and makes our home a more pleasant place. November 23, 2012
Rated 1 out of 5 by Junk 3 compressors and 2 capacitors in 6 years. Pure junk. September 27, 2012
Rated 4 out of 5 by Don't love heat pumps, but appear to be economical Wish there were more thermostats that were especially made for heat pumps. I would like to easily locate one that would let me program so it can get very cool at night when we are sleeping and then warm up to save us $$ on electric bills as well as change the temperature multiple times during the day (it would need more 4 programming periods per day). Beyond that the heat pump has functioned fine. Is a little loud at times, but so far it has been reliable. September 26, 2012
