Heat pump installers by Toronto area
Last updated: By HeatPumpIndex Evidence Desk
HeatPumpIndex tracks 618 Greater Toronto Area heating and cooling businesses, and publishes an area page for the 14 of them, in 7 boroughs and municipalities, that have enough local companies to rank. The front page counts something different and larger: every neighbourhood with at least one listing in it. Pick your neighbourhood below to see the top-rated businesses near you, ranked by the HeatPumpIndex score, each with its own profile: a claimed one carries a phone number, and every other one carries a request form.
Which Toronto neighbourhoods have the most heat pump installers?
The Greater Toronto Area areas with the most listed companies are Toronto (248), Oakville (45), and Oshawa (40), based on HeatPumpIndex's August 2026 dataset. Denser, older neighbourhoods and the larger municipalities tend to list the most companies. Every area page on HeatPumpIndex ranks them by the HeatPumpIndex score, never by paid placement, so the shortlist reflects real reputation.
