Distinguish a City of Duncan address from nearby North Cowichan when requesting work.
Planning furnace work in Duncan
A Duncan mailing address is not sufficient to determine the municipal boundary or approvals for a property. Provide the full project location and use the City’s official information as a starting point. For a nearby North Cowichan property, identify that jurisdiction explicitly.
Gas installation and replacement work needs the appropriate authorization. Ask the licensed contractor who will obtain the permit or applicable replacement authorization, which authority is responsible and what completion records you will receive. Other trades or changes to the building may need separate approvals.
- Which authority regulates the proposed work at this address?
- Who obtains the required permit or replacement authorization?
- What declarations or completion records will I receive?
Choose the right kind of request

Compare replacement optionsQuestions for your Duncan project
A furnace proposal should address heating needs, cooling goals and the existing distribution system together. Verify fuel availability, electrical scope and eligibility before comparing equipment or rebates.
- Confirm whether the existing heat uses gas, propane, electricity or another fuel.
- Compare furnace-only and heat-pump options against the same comfort goals.
- Include duct suitability, controls, maintenance access and installation approvals.
Confirm the current permit requirements for your exact property with the relevant authority and the qualified contractor. A municipal information link is a starting point; it is not a permit approval.
