Ottawa, ON · HVAC

The 25 Best-Rated HVAC in Ottawa

Ranked from 70 operating hvac businesses in Ottawa, ON that carry at least 20 Google reviews. Updated 2026-08-19.

How this is ranked

By Google rating, weighted by how many reviews it rests on. A rating is pulled toward the local average (4.78 across the 70 businesses considered) in proportion to how thin its review count is, so a lone 5.0 from 20 reviews cannot outrank a 4.8 from 900. No payment, placement or editorial judgement affects the order, and businesses that have claimed their listing get no lift — the mark below only says the listing has an owner behind it.
