After your home energy assessment, you will uncover opportunities to save energy. Find a contractor to perform energy efficiency projects and improvements in your home and receive rebates to help cover the cost.

For air sealing and insulation projects, you must choose a contractor via the find a contractor tool. If you complete any recommended air sealing and/or insulation projects energySMART lets you skip the paperwork— your contractor will deduct your rebate from your invoice so you save upfront.
