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.

*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.

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:
Zone | Cost-effective Models | |
| Zones 1 & 2 (hot) | 18-19 SEER/9.5-10 HSPF | |
| 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 years | 13-14 SEER/8 HSPF | 14PHX 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.
Great 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.
Hard 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.
Lennox Prices By Model
In order to offer an objective and equal comparison, we set the baseline below:
Each system includes: 3-ton outdoor condenser, 1300-1500 cfm air handler, programmable heat pump thermostat and without Lennox solar panel.

| $5,700 | Lennox Merit 13HPX | Oakland, CA | 1600 sqft |
| This is the first time I am using a heat pump. I love this unit so far, it has been operating without any major hiccups for three years now. I have to realize the reason there are so many negative complaints. The silent majority of satisfied customers never bother to show their appreciation by leaving a positive review. | |||
| $6,200 | Lennox XP17 | Tampa, FL | 3000 sqft |
| I installed this Lennox system about a year ago. Since installation, the system makes a scary noise every time it changes cycles. Despite repetitive checks, the technician has not been able to find anything wrong with the system. I am disappointed; the contractor claims that these heat pumps are too complex. In fact, he plans to cancel his contract with Lennox soon. | |||
| $6250 | Lennox XP15 | Philadelphia, PA | 1800 sqft |
| I bought this unit as a replacement for a Trane 2 ton unit. This was due to the system being extremely noisy. In addition, it was contributing to a higher electricity bill. When I had the new Lennox installed, it gave me a scare after a few months when it froze. However, the contractor was able to identify the problem and resolve it. Since then, it has not had any issues. I like Lennox and will definitely be buying a unit with a higher SEER rating. This will be from the savings am making on my reduced electricity bill. | |||
