Heat pump overview

If your energy bills are higher than you would like, you might look into getting a heat pump. Often, heat pumps run more efficiently than other heating and cooling units and can reduce electricity consumption by up to 50%

One common misconception is that heat pumps can only warm a room. Heat pumps also cool homes in the summer. Each Lennox heat pump operates using air transfers. In the summer, the pump transfers warm air from inside your home outside. In the winter, the pump moves cold air from the inside out.

If you live in a mild climate where the temperature rarely drops below 40 degrees, you can usually rely only on your heat pump in the winter. However, if you live in a colder region, you should pair a dual-fuel heat pump with a furnace.

Lennox sells many different types of heat pumps that can provide year-round temperature control for your home. Pumps vary in efficiency, power, noise level and price. When searching for a heat pump, you need to understand not only the available models, but also what to expect in terms of pricing, warranties and reviews.

Lennox heat pump series and models

Lennox provides many options for homeowners looking to install a heat pump. There are three series of Lennox heat pumps: Merit, Elite and Dave Lennox Signature Collection. 

Lennox heat pumps offer efficiency up to 23.5 seasonal energy efficiency ratio (SEER), which is the efficiency rating for cooling. Also, Lennox has up to 10.2 heating season performance factor (HSPF), which is the rating for heating.

In all cases, the size of the unit and the type of your home will affect the price, so be sure to contact a local professional for the most precise estimate.

"Rusting Coils"

1.0 rating
Very Unsatisfied

My unit is failed at 5.5 years. It games problems for over 6 months until it was finally determined that my evaporative coil had completely rusted out. This is a known problem within Lennox as there is an ongoing class action lawsuit in process for this very issue. I contacted who wanted all of the information including service records so they could plan their Cours of action which turned out to be nothing. I could have bought a Goodman and would have received better customer service. I will never buy another Lenox unfits.

We built our home in 2012 and installed a new Lennox heat pump. It started having issues during our second summer in the home, and it completely stopped operating this spring, 2019. Since it has a five year warranty, Lennox will not take any responsibility for replacing it. My experience with its customer service department was ridiculous. This appears to be an inferior product, so you are not saving any money by purchasing it. If you plan to live in your home more than ten years, it is my opinion it's worth spending the extra cash on a more reliable brand.

"Most expensive mistake ever. Don't buy Lenox heat pump."

1.0 rating
Very Unsatisfied

In July 2016 I purchased an expensive Lennox. The dealer told me my old unit was a fire hazard. I was a fool to fall for that, but I did the First winter it needed a new compressor. Ran 24/7 until the new compressor was installed. Granted this winter has been exceptionally cold, but it hasn't stopped running again. It is noisy, inefficient and a waste.My other unit is a Rheem. So much better!!!!! Lennox told me after the dealer gets the unit they are no longer interested. Go to the dealer with your complaints. As a senior, I cannot afford to replace it in only 2 years so I must suffer from the colossal waste of money. The most expensive mistake of my life. But in July in the desert you need air. Too bad it doesn't heat/cool all the rooms as well as the old unit did.

"Would not recommend Lennox"

1.0 rating
Very Unsatisfied

Didn't even see this model in the selection. I guess after they figured out what a crummy product this was they discontinued it. We had a Rheem for over 20 years with no problems. And we now have 2 xp17 units from Lennox. We bought these 5 years ago and have had nothing but problems with 2 separate units. They freeze up when we have a cold rain. Both blow out cold stale air when defrosting. No one seems to be able to fix this problem and Lennox wants us to contact our contractor who has not been able to fix this problem since we had it installed. Would not recommend Lennox.
