What do I need to get started?
The serial number and model number for each piece of equipment you purchased.
An email address. We will use this to send you confirmation of your registration.
If you're registering equipment in a newly-constructed home, we'll ask for:
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:
The serial, model and brand of other components in your system.

Much of this information will be on the invoice provided by your installing contractor. If you need help, please contact your installing contractor.
