Lennox Heat Pump Overview

Heat pumps double as air conditioners and heaters. If a house needs to be cooled, the heat pump will move heat from inside to outside. If the house needs to be warmed, it does the reverse. Lennox makes heat pumps in three different series, each of which contains a few models.

Merit Series

The Merit Series is the most inexpensive of the three types of Lennox heat pumps. The Merit Series contains two models: the 14HPX and the 13HPX. The only difference between these two is that the 14HPX has a SEER (Seasonal Energy Efficiency Ratio) of 14, and the 13HPX has a SEER of 13. SEER represents the relationship between cooling and energy input; a higher seer implies greater energy efficiency.

The 14HPX and 13HPX are equally efficient at heating during winter. Both have a HSPF (Heating Seasonal Performance Factor) of 7.7. For HSPF, higher is better; the value describes the percentage of energy used that directly becomes heat. The federal minimum HSPF is 6.8.

Both models operate at 76 decibels.

Elite Series

There are two models in the Elite series and they are intermediate in cost, sound, and efficiency.

XP13 has a SEER of 15.5 and an HSPF of 8.5. It runs at 76 decibels. XP14 is much quieter, at 71 decibels. It has a SEER of 16 and an HSPF of 9.5

XP16 is a two-stage model. This means that it has two parts, only one of which runs if not much heating or cooling needs to be performed. On days that are not especially hot or cold, it will be quieter and use less energy. XP16 has a SEER of 16.5 and an HSPF of 9.5. It makes 74 decibels of sound.

Dave Lennox Signature Collection

These are top-of-the-line Lennox heat pumps.

The XPG15 is a dual-fuel heat pump, which means that it can use electric and gas energy. It uses electric energy for cooling and low-level heating, then has the power to add gas energy to winter heating during extreme cold. It has a SEER of 16.2 and an HSPF of 9.2. Its sound rating is 92 decibels.

The XP17 has the capacity for dual fuel sources. In addition, it is equipped for easy installation of solar panels as a third power source. It is compatible with the 'icomfort' digital thermostat. XP17 has a SEER of 17.7 and an HSPF of 95. It runs as low as 62 decibels.

The XP21 model has similar features. In addition, it uses a two-stage model, like the XP16, to modulate its energy usage. If not much heating or cooling needs to be done, it doesn't go into full operation.

Energy Tax Credit

The Middle Class Tax Relief Act of 2010 provides $300 tax credits for the purchase of energy-efficient heat pumps. This credit applies to all of the above models except the 13HPX. An additional 30% credit, with no cap, applies to photovoltaic installation accompanying the XP21 and XP17 models in the Signature Collection.


The Merit models come with five-year warranties. All the Elite and DLSC models have the same five-year parts warranty, along with ten-year warranties for their compressors. The five-year warranties can be expended for a price.

"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.
