An additional fee is applied for homes over 2,500 square feet.

If after the post-retrofit evaluation, it is determined you are unsuccessful at completing the required upgrades for incentives. A revisit can be completed at a later date for an additional fee.

What to Expect During a Home Energy Evaluation

The energy evaluation is conducted on-site at your home. The initial (pre-upgrade) evaluation takes approximately 2–3 hours. A second (post-upgrade) evaluation takes up to 1 hour.

The energy advisor will conduct a basement-to-attic assessment of your home's insulation, heating, cooling, and other energy use.

A blower door test will be conducted to test for air leaks, which can cause wasted energy, uncomfortable drafts and poor air quality.

Your home will be given an energy rating using the Natural Resources Canada rating system — the lower the rating the better.

You will receive a full report outlining recommendations for improvements to help reduce your energy bills and increase your home's comfort.
