If you take just a few moments to register your equipment with us, we can keep you up to date on equipment information and offers.

If you're registering Elite® Series or Merit® Series equipment, you may be eligible for valuable supplemental coverage under Lennox's Extended Limited Warranty program.

What is the Extended Limited Warranty Program?

For eligible Equipment, Lennox’s Extended Limited Warranty Program supplements the Limited Warranty by extending the Warranty Period from five (5) to ten (10) years, subject to the terms and conditions of the Extended Limited Warranty. The Extended Limited Warranty is only available for Equipment used in a Residential Application, and only covers the original owner(s) of the premises (at the time of installation) where the Equipment is originally installed.

An email address. We will use this to send you confirmation of your registration.

The date you closed on the purchase of this home.
If your equipment was added on or replaced in an existing home, we'll ask for:
The date of installation.
The name and address for the dealer or contractor who installed your equipment.
And if your equipment qualifies for an extended warranty with registration, we will also ask for:
