Quick answer
As a ballpark — not a quote — a new gas furnace installation typically runs $4,500 to $9,500 or more, confirmed after a home assessment. In Dunbar, where homes and additions tend to be larger than average, correct furnace sizing and duct capacity play a bigger role in where a specific job lands within that range.

A gas furnace installation in the Dunbar area generally falls between $4,500 and $9,500 or more as a ballpark based on current market conditions, not a quote. Furnace size, ductwork condition, venting requirements, and access to the mechanical room all factor into where a specific job lands. Your exact price is confirmed by the CANRO office after a short assessment.
Dunbar's larger lots and homes, many with additions or finished basements added over the decades, mean a proper load calculation often points to a bigger furnace than a like-for-like swap would assume. Installing the right size for a genuinely large home — and confirming the ductwork can actually deliver that airflow to every room, including additions — is more involved than a straightforward installation in a smaller, unmodified house, and that's reflected in where the job lands within the range.
A proper installation includes a load calculation based on the home's actual current square footage, gas line connection and testing, venting that meets current code, ductwork capacity verification, the municipal permit, and full commissioning with a combustion and safety test before the crew leaves. Skipping the load calculation step is exactly how a furnace ends up undersized for a home that's grown since it was originally built.
For a home with a finished basement or a rear addition, it's also worth having the technician confirm during the assessment that ductwork feeding those spaces was sized properly the first time. Occasionally it wasn't, and installation day is a natural point to correct that alongside the furnace itself rather than treating them as separate projects later on.
Installing a furnace where one has never existed — a new addition with its own zone, for instance — is a different scope than replacing what's already there, and tends to land toward the higher end of the range since it involves new ductwork and gas line runs from scratch. Extending an existing furnace's reach to cover a newly finished space, by contrast, sometimes just means resizing and rebalancing what's already in place, which can be less involved.
Call the office to book an assessment. A technician will walk through the home, note any additions or finished spaces, check the existing ductwork and venting, and give you a firm number before work starts — the ballpark above is a starting point for that conversation, not the final word.
Safety note
If you ever smell gas during or after an installation, leave the home immediately and call FortisBC at 1-800-663-9911 from outside. Gas furnace installation must be performed and commissioned by a Technical Safety BC licensed gas fitter; CANRO holds gas licence LGA0043870.
No — it's a ballpark. Larger homes with additions sometimes land toward the higher end because of sizing and ductwork needs, but your exact price is confirmed after an assessment.
An addition changes the home's total heating load, which can mean a larger furnace and additional ductwork capacity are needed to heat the added space properly.
Yes, gas furnace installations require a City of Vancouver permit, and CANRO handles that as part of the installation process.
It can affect venting termination requirements, which is assessed during the visit, though it doesn't automatically raise or lower the price on its own.
It can take longer than in a smaller property, particularly if ductwork needs modification to properly serve an addition — this is discussed upfront.
Yes, removal and disposal of the old unit is part of a standard installation — confirm the specifics when you get your quote.
