Lennox Air Conditioner Prices, Reviews and Buying Guide 2018

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

For over a century, Lennox has been doing the manufacturing of quality ACs. The company thus offers widespread listings of central ACs units. The major reason consumers go for a Lennox product is for the reason that they are reputable and highly efficient. This lineup of conditioners comes at different prices to fit the budget of different consumers and their needs. As a trusted company, Lennox provides customers with the right information you require to make the ultimate decision when purchasing a reliable air conditioner. The top Lennox conditioners come in Signature model, Elite and Merit models.

Lennox’s Exclusive Features

1. Aluminum Outdoor Coils For Partial Models

Those of you who read our Trane Air Conditioner Review before already know that Trane is famous for using aluminum coils to enhance the ability of anti-corrosion and increase the efficiency. Lennox starts to equip aluminum coils for 18+ SEER models since a few years ago. Aluminum coils perform better in coastal areas as aluminum is more corrosion resistant to salty air.

The cons for aluminum coils is that once your coils break or leak, you have to replace the whole coils as it is hard to be welded. However, we don’t think this is a really big problem as Lennox offers more than 10 years warranty for most coils. Once your coils break in 15 years, you can replace it with a high-efficient coils.

2. 26 SEER Efficient Variable-Capacity Compressor

In 2016, Lennox releases the 26 SEER air conditioner (Lennox XC25) which shocks the industry. 21 SEER (from Trane and Carrier) used to be the highest SEER in the residential air conditioners and 26 SEER means 20% more efficient than the 21 SEER. But don’t get me wrong and we don’t recommend you to buy it right now. Newest models equal to highest initial cost and repair fee. We will analyze which model is proper for you later in the below part.

3. Sun Source

Lennox solar-ready system is exclusive in all the residential HVAC market and only support for XC25, XC21 and SL18XC1 model. You can also find the sun source heat pump from Lennox.

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 feedbacks of Lennox contractor, 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.

Cons For Lennox AC

Lennox parts are expensive and hard to find

In most air conditioner repair cases, you can expect to get your unit fixed in 24 hours, but you have to wait for weeks when it comes to Lennox. Lennox is completely proprietary and you can not find the parts in the market. If your air conditioner is broken in the hot season, it is definitely a nightmare.

Model Analysis and Recommendation

Note: 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.

Best Cost-Effective Lennox Models For You

As we have discussed in our central air conditioner guide, the SEER is the most important parameter deciding the initial equipment cost and future energy savings.

Higher SEER Models can not always pay your money back. We developed a SEER Savings Calculator to help find a better balance between equipment cost and electricity cost. This tool can automatically load your local power rate and yearly cooling hours when using Chrome explorer. You can also adjust these inputs manually to get a more accurate result.

Contractor’s Review For Lennox

Most "old timers" familiar with Lennox can remember their "Pulse" and "Complete-Heat" fiascoes. Lennox has a good reputation in the market although a few cases of negative comments are always possible. A professional HVAC technician will do the proper installation and guide on how to operate your conditioner. Lennox products are energy star rated and are thus trusted by a huge number of consumers. Most service calls on these conditioners are due to human error on poor maintenance and poor installation of the AC. If your Lennox breaks, their logistics chain is so poor due to proprietary red tape, that it often takes 3-5 weeks to get the parts.

The people who installed this were great. After recieving quotes of 25,000 and 15,000 I was ready to look for a different brand but the third guy walked in and started talking seer and what he thought I needed. Finally we settled on the listed models and the rest is history. Installation was great and it has kept my home cool though out the summer. I not looking fwd to replacing the downstairs unit but if and when I do I am calling these guys.

Before I go out and get something I like to do a little research first so I looked up the best 3 ton AC and Lennox was among those that came highly recommended. I decided to go with Lennox basically because it had fewer nasty reviews. So far I can’t complain. I count myself lucky because I know there are a lot of home appliance companies that don’t live up to their billing. I thought it would be nice to put this here so that someone else can have confidence in Lennox.

I just moved to this house about 4 months ago and the AC needed replacing. It had a lot of issues that needed fixing and it was going to cost a lot so I thought this is the way to go. We install the XC25 to replace the old XC14. The Lennox XC25 performs amazingly in the long-term saving.
$6,690Lennox XC21Phoenix, AZ3000 sqft
What a disappointment this has turned out to be. I wonder who gets the luck of buying home appliances that just work like they should. This AC keeps breaking down and I think soon it will be useless. I have only had it for 8 months and it can’t go a month now without needing repairs.
$5950Signature Collection XC17Los Angeles, CA2800 sqft
Terrible piece of equipment. Why won’t they take it back or repair it? The company response is poor yet this thing cost me an arm and a leg to get. Someone from the company should help customers like myself out, this is not a good look.
