How long does it take to install a furnace?

A typical furnace install day

1. Shut down and remove the old furnace.
2. Set the new unit; adapt the plenum, returns and supply as needed.
3. Run high-efficiency venting and the condensate drain; confirm gas sizing.
4. Wire the thermostat and controls; start up and check temperature rise and gas pressure.
5. Walk you through the system and arrange the TSBC inspection.

What adds time

Converting from an old 80% to a 96% furnace (new venting), reworking undersized return air, tight closet installs, or adding cooling all extend the day. We flag these at quoting. Explore furnace services.

BC Permits and Technical Safety BC Inspection: What to Expect

Every furnace replacement in British Columbia requires a gas permit issued through Technical Safety BC before work begins. CANRO pulls this permit on your behalf as part of every installation -- it is not optional, and any contractor who skips it is putting your home insurance and occupancy at risk. The permit covers the gas-line connection, venting configuration, and all electrical tie-ins. Once the furnace is running, Technical Safety BC sends an inspector to verify the installation meets BC Fuel Safety Regulations and the BC Plumbing Code.

Inspection timing varies by region: in Metro Vancouver most inspections are scheduled within 1-3 business days of the permit being filed. The inspector needs access to the furnace room and may ask to see the equipment data plate and the venting run. This step adds no time to your install day itself, but plan to be available or have someone 18+ present when the inspector arrives. CANRO coordinates directly with Technical Safety BC and shares the inspection notice with you as soon as it is booked.

• CANRO holds gas licence LGA0043870 and boiler licence LBP0046450 -- your permit is filed under our licence numbers
• Permit fee is included in your quoted installation cost -- no surprise add-ons
• Unpermitted furnace installs can void manufacturer warranties and homeowner insurance policies
• If your home is in a strata, the permit record is your proof of compliant work for the strata council

How Metro Vancouver Homes Affect Your Installation Scope

The age and style of your home shapes what happens on install day more than almost any other factor. Pre-1980 Metro Vancouver houses -- common in Burnaby, East Vancouver, New Westminster, and North Delta -- were often built with oversized gravity-fed duct systems designed for much less efficient equipment. A modern high-efficiency furnace moves air at a different static pressure, so our technicians assess your duct sizing before confirming the replacement unit. In many cases the existing ducts work fine; in others, a supply or return modification adds 1-2 hours to the job.

Condos and newer townhomes present a different set of constraints. Fan-coil closets are tight, and venting must route through an exterior wall approved by the strata. Multi-family buildings in Vancouver, Burnaby, and Coquitlam increasingly have gas-supply pressures and meter configurations that require a pressure check before the new appliance is fired. Our technicians carry calibrated manometers on every job precisely because BC Hydro and FortisBC infrastructure across the Lower Mainland is not uniform. All of this is diagnosed during the pre-install site review, so surprises on install day are rare. Learn more about what a full assessment covers on our furnace services page.

• Rancher homes and crawlspace houses in Surrey or Langley often need flexible duct connectors re-routed for the new unit footprint
• High-rise condo venting must meet both Technical Safety BC standards and strata building bylaws
• Older galvanized duct with significant rust or collapsed sections should be replaced before or during the furnace swap
• Homes with a combination furnace and central air conditioning coil may need the coil repositioned to match the new unit height
