What Oshawa homeowners say

Electric unit in the condo
Building would not approve gas. They framed and installed a recessed electric linear unit in a day and it looks built-in, not bolted on.

Honest advice on sizing
I wanted a bigger unit. They explained why it would overheat the room and recommended a smaller model — and were right.

Ravi S. · 2026-01-19

Good install, unit was back-ordered
The install itself was excellent. The unit took an extra two weeks from the supplier, which they kept me updated on throughout.

Lauren F. · 2025-10-30

Fixed a bad previous install
Another company left the vent termination too close to a window. Diamond re-routed it to code and documented the correction.
