Lennox International produces climate control products like air conditioners, heat pumps, furnaces, air quality equipment and more. The company partners with a network of authorized Lennox dealers to sell and service its equipment for both residential and commercial customers. Lennox provides a basic limited product warranty and extended warranty options.

Key insights

  • The Lennox limited warranty includes coverage for parts and specific product components.
  • You can get a free extended warranty on your Lennox product by registering it within 60 days of installation.
  • The basic warranty does not include labor costs, like service fees or diagnostic charges.

Lennox warranty coverage

Lennox includes a basic limited warranty on its products. Warranty certificates are posted on the company’s website and may differ based on the model and the installation date (before or after Feb. 8, 2022).

The basic limited warranty for products installed after Feb. 8, 2022, in residential settings covers the costs associated with repairing or replacing parts. For example, with the Dave Lennox Signature Collection warranty, the compressor and parts have 10-year coverage. The heat exchanger is covered for the unit's lifetime for the original purchaser only. Otherwise, it’s covered for 20 years for subsequent owners.

Labor costs don’t come with the basic limited warranty. However, Lennox provides the option to extend the warranty or add labor cost coverage on eligible equipment through the Warranty Your Way program. You can get this free warranty extension by registering your product within 60 days of installation. The program lets you choose whether to extend warranty coverage on certain components and/or add labor cost coverage.

Lennox coverage exclusions

In certain circumstances, Lennox will not cover the costs of repairs, even if the manufacturer’s warranty has not yet expired. The warranty certificate details several exclusions, so it is important to read that document carefully before installation.

For instance, the company will not provide replacement parts if the air conditioning unit has moved from its original installation location. Additionally, the unit must have been installed and serviced properly by a licensed HVAC installer or contractor. The warranty certificate includes a full list of conditions and limitations to coverage.

Lennox product registration

To register your Lennox product, visit the company’s “Product Registration” page and click on the link for the “Warranty Your Way Registration Portal.” You’ll need the serial number, model number and installation date.

Lennox does not require product registration to get warranty coverage. However, if you purchase an eligible Lennox product and register within 60 days of installation, you could receive free extended warranty coverage.

Lennox warranty cost

There is no additional cost for a Lennox manufacturer’s warranty (it’s included with your original purchase), but the company does offer service plan coverage. The prices for extended coverage vary depending on the plan.

Lennox extended warranty

In addition to the free warranty extension program, Lennox offers an extended service agreement plan that covers costs not included in the basic manufacturer’s warranty, like labor, refrigerant and trip charges. Coverage periods range from three to twelve years, and prices vary depending on the plan. You can contact an authorized Lennox dealer for more information on this program.

Factors to consider when buying an extended appliance warranty

Unlike other extended warranties that just prolong the manufacturer’s warranty, the Lennox extended warranty is more of a service plan. It includes regular maintenance in addition to service calls for repairs.

Lennox does not publicly disclose plan costs, so you’ll need to contact a Lennox dealer for pricing information. You should compare those prices with typical HVAC yearly maintenance costs to decide if the plan is worth it.

How to file a claim for your Lennox appliance

You must contact an authorized Lennox dealer or an HVAC technician to file a warranty claim. Keep in mind that warranty claims must be submitted within 45 days of product failure, so don’t wait to call and request an assessment. Also, the warranty does not cover labor costs, so be prepared to pay a service charge for diagnostics.

Lennox warranty vs. home warranty alternatives

HVAC repair and replacement costs are typically some of the most expensive for homeowners. You could spend between $160 and $530 or more to repair your unit and $5,000 or more to buy a new unit. If you don’t have adequate savings to prepare for these unexpected expenses, it could cause a significant financial setback.

A home warranty can be useful in these situations. Appliance home warranties typically cover the repair or replacement costs of HVAC systems like air conditioners and heat pumps.

Pros and cons of Lennox warranties

You aren’t required to register your Lennox product to get warranty coverage. This may be helpful if you’ve purchased a home with an existing Lennox system. However, the company does incentivize product registration by offering a free extended warranty when you register.

A drawback is that labor costs don’t come with basic coverage, which likely accounts for a large portion of repair costs. In addition, the Lennox warranty on select models only covers parts for five years. For comparison, some of its competitors include ten-year coverage on parts.


  • Registration isn’t required to get warranty coverage
  • Free extended warranty with labor coverage available


  • Labor costs not included in basic coverage
  • Parts costs for specific models only covered for five years

  • Always have your HVAC unit serviced by a licensed professional.
