Home Energy Retrofits in Markham
Markham's large detached homes face real heating and cooling loads, and many older subdivisions still rely on first-generation high-efficiency equipment. HES helps Markham homeowners qualify for approved cost-neutral retrofit programmes, no money out of pocket.
About this programme
About this programme in Markham
HES helps Markham homeowners assess whether their property fits an approved retrofit programme and handles the qualification process on their behalf. HES is not a contractor — all installation work in Markham is performed by approved programme contractors.
If you'd like the full overview of how the broader programme works, our How It Works section walks through every step, and our FAQ answers the most common questions from homeowners.
