Lennox Heat Pump Prices and Reviews 2021


Note: Before you dive into the specific brand review, we highly recommend you to read our elaborate Heat Pump Buying Guide in advance, there are several crucial steps you need to take before you even start to think about the brand.

Lennox is one of the leading manufacturers of equipment for improving indoor comfort. In addition to being extremely energy efficient, Lennox has also worked hard to make their products some of the quietest. Some of their heat pumps have a noise level as low as that of modern refrigerators.

As proof of the heat pumps efficiency, they received the Energy Star rating for most efficiency, twice in a row. This was in the year 2012 and 2013. At the time, their heat pumps were rated as the most efficient heat pumps on earth. One of their unique features is the provision of a solar-powered heat pump. With the power of the sun, one can control the climate of their home, essentially free with the Lennox heat pump. Another unique feature of the Lennox heat pumps is the humidity control option. With this option, one can control the level of molding in their home. Consequently, one will improve the breathability of the air inside the home.

Lennox Model’s Recommendation

ModelSEERHPSFSound LevelCompressorSolar-Ready

*iComfort is a Lennox’s patent which can connect to WiFi thermostat to optimize performance efficiently.

*Lennox Communicating System is an optional function for high-end models with a monthly fee. In my opinion, it is not worth the money. You can install a $200-$300 wifi ColorTouch thermostat instead.

• Merit Series: The Merit Series is priced affordably with efficiencies up to 14 SEER and 8.2 HSPF.

• Elite Series: The Elite Series is a mid-level product featuring SEER ratings that range from 14-20 and HSPF ratings from 9.5-10. Models are available with either a single-stage or two-stage compressor.

• Signature Series: The Lennox Signature Series provides exceptional levels of comfort and efficiency. Models in this series are extremely quiet and provide 23.5 SEER and 10.5 HSPF ratings. The XP25 and SL18XP1 can be combined with compatible solar panels to reduce energy consumption by up to 50 percent.

Take Away For Lennox Models

When you’re looking for the most cost-effective heating, the strategy is to find the balance between furnace cost and energy costs. Let’s use the zone map to identify efficiency levels for each that strike that balance:

Suggested SEER and HPSF
Cost-effective Models
Zones 1 & 2 (hot)18-19 SEER/9.5-10 HSPF
XP20, XP21, XP25
Zone 3 & 4 (moderate)14-15 SEER/8.5 HSPF
Zone 5 (cool)15-17 SEER/8.5-9.5 HSPF
XP16, XP14
Zone 6 (cold)(18 SEER/9.5 HSPF) or (AC + Furnace)SL18XP1
Zone 7 (very cold)(18 SEER/9.5 HSPF) or (AC + Furnace)SL18XP1
Plan to move in the next few years13-14 SEER/8 HSPF14PHX or other low-end brands


Note: In Zones 6 and 7, the coldest zones, a system with an efficient gas furnace and small central air conditioner is also a good option; Lennox is one of the premium brands with higher initial cost. If you have the plan of moving house in less than 5 years, we recommend installing some quality but low-end level brands like Payne, Ruud or Armstrong.

What Customers Say About Lennox

Please note that we always got more bad reviews than good reviews because people have less time to write a review when their heat pumps work perfectly. But you can take these tags to ask your contractor how they solve it once problem happened.

QQ20151025-2Great energy efficiency and reliability

This conclusion was reached after doing a thorough review of people who had used a number of heat pumps. It came out that most customers were impressed by the reliability of the Lennox heat pumps. People who had experienced with other high-efficiency heat pump brands claimed Lennox heat pumps required less maintenance. In addition, they claimed they noticed the greatest drop in their electricity bill after installing a Lennox.


Solar panel

The solar panel is the unique feature only for Lennox, most customers satisfied with the high efficiency of Lennox solar model.

Lennox Sun Source Worth the Money?
Please note that this is not a default built-in function but you need to pay extra thousands of dollar. So the main question is: can I get the money back in the long run? According to the feedback from Lennox contractors, you can only save 5%-15% of daily usage of power which absolutely makes no sense. However, the solar-supported unit can qualify for at least 25% federal and state tax credit. Some utility companies still offer $2-$5 per watt rebate. So if you can find good government support to deduct part of the initial cost, it is worth your money, especially for A/C heavy users.

QQ20151025-1Hard to find replacement parts

After review of the customer feedback, this came out as a common problem. Most Lennox parts are unique and not interchangeable with other heat pumps. In addition, the company is regularly overhauling. Consequently, when the unit required even the simplest of replacement, finding the part could be a nightmare. This had led to many frustrated customers. Sometimes it had caused them to buy a new unit because a heat pump they bought three years ago no longer had its parts in production.

  1. We’re very interested in having a Ductless heat pump installed in our 14′ x 19′ Sunroom that’s probably 80% glass. We want something that will be REAL quite. Looking at your chart on pricing, it doesn’t give me any type of estimate for a 1.5 – 2.0 ton Ductless system.
    Is there anyone in Michigan who could give me a good idea?
