I had an HRV installed by Service 1st and I highly recommend them. It was a challenging job in a small space but they did excellent work. They went above and beyond.

ProScore profiles are built from publicly available information and official public registries, and scored using ProScore’s own methodology. We check this data against third-party sources and work to keep it accurate, but records change and errors can occur. A ProScore is informational only — it is not a guarantee, endorsement, or recommendation. Before hiring any contractor, you should independently verify and confirm all relevant credentials, licences, insurance (including WSIB coverage) and references directly with the contractor and the issuing authority. If something here looks wrong, let us know and we’ll correct it promptly.
