Lennox offers a variety of warranties, including the Basic Limited Warranty, the Extended Limited Warranty and the Comfort Shield program, which each have their own specifics.
Warranties are meant to protect you against faulty parts and installation practices, but are often extremely specific about what is and what is not covered.
Lennox does offer warranties on the air conditioners in its Dave Lennox Signature, Elite and Merit product ranges. Each of these have their own specifications and can be extended if necessary.
Understanding what a warranty is
Chances are, if you have just started thinking about buying a new air conditioner, then the warranty of this product will be the last thing on your mind.
However, air conditioners are an expensive investment and understanding why top brands offer warranties with their products can really pay out in the long run.
A warranty works almost like insurance for your appliance, and it can help to protect you if there is unexpected damage to your air conditioner after it has been installed.
However, the most important thing to note about warranties is that they only tend to cover specific parts, for a limited period of time, and under very specific circumstances.
What is the warranty on a Lennox air conditioner?
Lennox was founded over 125 years ago by Dave Lennox and has been one of the most trusted brands for all HVAC products and solutions since then.
One of the reasons why Lennox air conditioners continue to be a fan-favorite among professional HVAC technicians is because Lennox focuses on building products that are meant to last.
Even though Lennox claims to use only the best materials when building their appliances, we all know that sometimes, even with the best possible quality assurance measures, these appliances just do not quite work the way that they are supposed to.
This is why Lennox offers industry-leading warranties and coverage on its Dave Lennox Signature, Elite and Merit product lines under the brand’s Basic Limited Warranty, as follows:
| Product line | Coverage for components | Coverage for compressor | Coverage for heat exchanger |
| Dave Lennox Signature | 10 years | 10 years | 20 years or Limited Lifetime |
| Lennox Elite | 5 years | 10 years | 20 years or Limited Lifetime |
| Lennox Merit | 5 years | 5 years | 20 years |
However, the exact coverage of this Basic Limited warranty may vary between models. Hence, it always best to reach out to your trusted Lennox dealer for the specifics about what is covered under your warranty.
If you are worried about this basic warranty just not quite covering it, Lennox also offers buyers the opportunity to extend their Basic Limited warranties at no additional cost (on select products, with registration).
They can do this through the Extended Limited Warranty and Comfort Shield offerings.
How to ensure that you get the most out of your Lennox warranty
Knowing exactly what your warranty does and does not cover is tricky and often comes with various strings attached.
This is why it is so important to know the exact restrictions of your specific model’s warranty. However, as a good rule of thumb, following these steps should ensure that your warranty remains valid for when you need it:
- Purchase and install the air conditioner through professionals who are registered with Lennox
- Complete regular maintenance tasks as and when required (be sure to keep a record of this)
- Use certified professionals for all your repairs
About the Comfort Shield program
Often times, the labor costs of repairs and installation can make up the majority of your bill when something goes wrong with your air conditioner.
While your warranty may cover the components that were at fault, it will not always cover the additional labor costs.
The Comfort Shield program offers additional coverage (split into three different tiers) for labor costs. Furthermore, it can be purchased up to five years after the installation of your Lennox air conditioner.
About the Lennox Extended Limited Warranty
All eligible products that you purchase from Lennox will come standard with the Basic limited Warranty.
However, you can extend this warranty and change it to an Extended Limited warranty if you register your product within 60 days (only in select areas).
This Extended Limited Warranty can be summarized as follows:
| Product line | Options | Coverage for compressor | Coverage for heat exchanger | Coverage for all other parts | Coverage for labor |
| Dave Lennox Signature | Option 1 | 12 years | 20 years or Limited Lifetime | 12 years | 0 |
| Option 2 | 10 years | 20 years or Limited Lifetime | 10 years | 3 years | |
| Lennox Elite and Lennox Merit | Option 1 | 10 years | 20 years or Limited Lifetime | 10 years | 0 |
| Option 2 | 10 years | 20 years or Limited Lifetime | 7 years | 3 years |
