How much should I budget for ductwork replacement in Vancouver?

Ductwork replacement in Metro Vancouver typically runs $3,000–$12,000 for a standard single-family home, with most homeowners landing in the $5,000–$8,000 range. The wide spread comes down to your home's size, the complexity of the existing system, and whether you're doing a full replacement or a partial upgrade.

For a smaller home or townhouse (under 1,500 sq ft), expect to pay $3,000–$5,000 for a straightforward replacement using flex duct. A mid-size home (1,500–2,500 sq ft) with a mix of rigid sheet metal and flex duct typically runs $5,000–$9,000. Larger homes, multi-level layouts, or older Vancouver Specials with awkward crawlspaces and tight ceiling cavities can push costs to $10,000–$15,000+, especially if asbestos-wrapped ductwork needs to be removed and disposed of properly — which is common in pre-1980 homes across East Van, Burnaby, and South Vancouver.

What drives the cost up in Vancouver specifically is the combination of high labour rates (HVAC journeymen typically bill $95–$130/hour here), the age and layout of local housing stock, and the fact that many older homes were never designed for forced-air systems. If your home has a finished basement or cathedral ceilings, expect to pay more for the access and patching work. Asbestos abatement, if required, adds $1,500–$5,000 on top of the ductwork cost and must be done by a licensed abatement contractor — not the HVAC crew.

Material choice matters too. Rigid sheet metal is the gold standard — more durable, better airflow, and longer-lasting — but it costs roughly 20–30% more than flexible duct. Flex duct is faster to install and works well in accessible areas, but it degrades faster in Vancouver's damp conditions if it's not properly supported and sealed. A good contractor will typically use a combination of both.

When to Replace vs. Repair

If your ducts are leaking, poorly insulated, or more than 20–25 years old, replacement often makes more financial sense than patching. Leaky ducts can waste 20–30% of your conditioned air — a real problem if you're installing a new heat pump and want to maximize efficiency. Many homeowners pair ductwork replacement with a heat pump installation, which is smart timing since the HVAC contractor is already in the system.

Speaking of heat pumps — if you're upgrading to one, check out the CleanBC Better Homes rebates at betterhomesbc.ca or call 1-844-881-9790. Heat pump rebates can reach up to $16,000 for income-qualified households, and bundling your ductwork replacement with a heat pump install can make the whole project significantly more cost-effective.

This is not a DIY project. Ductwork design affects your entire HVAC system's performance, and improper installation leads to pressure imbalances, moisture problems, and poor air quality. In BC, any work connecting to gas appliances requires a licensed gas contractor registered with Technical Safety BC (TSBC). Even for electric systems, the HVAC contractor should be pulling the appropriate permits with your local municipality.

Your next steps: Get at least three quotes from licensed HVAC contractors in our directory at the Vancouver Construction Network. Ask each contractor to do a load calculation (Manual J) and duct design assessment before quoting — anyone who gives you a number without looking at your home's layout isn't giving you an accurate estimate. Also ask specifically whether your existing ductwork contains asbestos insulation, especially if your home was built before 1985.
