View Tempzone HvacBefore you hire in Kanata
In Ottawa installing an air conditioning unit or a heat pump does not require a building permit.
Zoning still governs where the outdoor unit may sit. Exempt from a building permit still means the work must comply with the Ontario Building Code and any applicable law, such as the Zoning By-law.
Designated heritage buildings and properties inside a Heritage District Overlay are not covered by these exemptions, and the City asks owners to confirm with a Building Client Service Centre before starting.

Common questions
Hiring in Kanata
Kanata is Ottawa's west-end tech hub, a mix of established 1990s and 2000s subdivisions in Kanata Lakes, Bridlewood, and Katimavik plus newer builds further west. Because much of the housing stock is now 20 to 30 years old, the most common projects here are first roof replacements, deck rebuilds, window and door upgrades, and basement finishing. The service businesses below serve Kanata and the wider west end.
A furnace or heat pump that is oversized short-cycles and wears out early. A good Ottawa installer does a heat-loss calculation for your home rather than matching the old unit's number.
Cold-climate heat pumps now work through Ottawa winters and can cut energy costs. Rebate programs change year to year; ask which current federal or provincial rebates your project qualifies for.
