"Very dissatisfied with quality of their heat pump"

Not good quality product.

"Multiple defects inside the unit, total freon loss"

1.0 rating
Very Unsatisfied

The tubing inside the unit suffered from two separate failures two weeks apart leading to total loss of freon. The first failed under ac operation, and the second failed under heating operation. In both instances, Lennox customer service insisted they cannot produce a defective product (!!!) and refused to assist. This model failed in multiple locations internal to the outdoor unit, and Lennox will not be able to incorporate improvements because they cannot accept responsibility. This gives an extremely poor outlook for this model, since defects will go unreported to engineering. More importantly, I can't imagine any other product or company I could possibly recommend less. With this experience, I certainly cannot be the only one.

My issue is about company support. While under warranty I reported an issue while dealer claimed no issue. This wall all within 2 months of warranty expire. Three days after the expire, it crapped. Lennox said adios I was out of warranty

"Lennox 14HPX Heat Pump Review"

5.0 rating
Very Satisfied

We've owned this heat pump for the past 5 years and it's never failed! The past few winters in the Northeast have been brutally cold, dipping below freezing quite often. Regardless, it keeps working! We've also saved a ton of money by using the built-in automated temperature settings to lower the heat during different times of the day. My only complaint is when it kicks on, it pushes air through the vents really loud.

"Don't buy Lennox"

1.0 rating
Very Unsatisfied

Had a Lennox heat pump installed in 2010 for a large room over garage. Unit is used on occasional basis. It as broken down 2 times in 5 1/ 2 years. Melted heat strips, shorted blower. Still not repaired after 2 weeks. Waiting on parts. We have a Trane unit on the main level with minimal issues for over 10 years. Buy the Trane. It is very reliable.

Other 14HPX Reviews

A post on hvac-talk.com from a homeowner trying to decide between the 14HPX and a more expensive Lennox model was advised by professional members that the best Lennox is the Signature series and that the 14HPX is a low-end unit. There are also posts on the same site regarding problems with high and low pressure faults and with problems that appear to be the fault of technicians, including overcharging with Freon.
