Step 1: Choose qualifying equipment and licensed contractor (if applicable)

For contractor install window and sliding glass door rebates, windows and sliding glass doors must be installed by a licensed contractor. We recommend that you obtain several bids for comparison.
For self-install window and sliding glass door rebates, homeowner must certify windows and sliding glass doors were installed according to manufacturer’s instructions.
Ensure windows and sliding glass doors meet required efficiency ratings.
Windows and sliding glass doors must be replacing existing windows and sliding glass doors.

Step 2: Ensure your home qualifies

Complete and submit a rebate application within 120 days of qualifying equipment installation.
Include a copy or electronic image of the final invoice and supporting documentation, which must include total number of windows and sliding glass doors installed, u-factor of all windows and sliding glass doors, and cost (bids and estimates are not accepted).
