What Does Furnace Replacement Actually Cost in BC?
Furnace replacement in BC runs $3,500–$8,000 fully installed including permit and labour for most residential homes in the Lower Mainland. The wide range comes from equipment tier, home size, and whether any modifications to ductwork, gas lines, or venting are required.
Below is a full breakdown by furnace type, plus the factors that push cost higher or lower in Surrey, Vancouver, Burnaby, and Langley.
Furnace Replacement Cost by System Type
Single-Stage High-Efficiency (96% AFUE)$3,500–$4,800 installed. Runs at full capacity whenever on. Best for smaller homes or budget-conscious replacements. Still a major efficiency upgrade over 80% units.
Two-Stage High-Efficiency (96–97% AFUE)$4,500–$6,500 installed. Runs at ~65% capacity most of the time. Better comfort, quieter, lower gas bills. The most popular choice in BC for medium to large homes.
Modulating Furnace (98% AFUE)$5,500–$8,000 installed. Adjusts output continuously in small increments. Best efficiency, best comfort, lowest operating cost. Overkill for smaller homes but ideal for large open-plan layouts.
Furnace + AC Bundle$6,500–$11,000 installed for furnace + central AC together. Bundling saves $500–$1,200 in labour vs. installing separately. Most cost-effective way to get both heating and cooling.
Furnace + Heat Pump Hybrid$7,000–$13,000 before rebates; $4,000–$9,000 after CleanBC rebates. Heat pump handles 85–90% of heating, gas furnace activates as backup. Maximum efficiency with gas reliability.
Switching to a Heat Pump Instead$5,000–$14,000 before rebates; $3,000–$9,000 after. Eliminates gas heating entirely. Also provides air conditioning. Worth comparing at quote time.
What BC Labour Costs Include
Labour for a standard furnace replacement in the Lower Mainland runs $800–$1,800. This covers:
- Removal and disposal of the old furnace
- Installation, gas line connection, and leak test
- New venting (PVC or stainless) if required by code or equipment change
- Electrical connection and controls wiring
- BC Safety Authority gas permit (required on every installation)
- Final inspection and commissioning
Labour runs higher when: the furnace location is difficult to access (crawl space, tight mechanical room), new venting runs are long or require through-wall penetrations, or ductwork modifications are needed to balance airflow with the new unit.
Cost Factors Unique to Lower Mainland Homes
A few things specific to Surrey, Vancouver, Burnaby, and Langley installs:
- Strata buildings: Condo and townhome furnace replacements in strata buildings sometimes require strata council notification or approval before work begins. We advise on this upfront.
- Old B-vent to PVC conversion: Many BC homes have older B-vent or single-wall vent systems that need to be replaced with PVC when installing a 96%+ condensing furnace. Add $300–$700.
- Gas line upgrades: If your existing gas line is undersized for a larger furnace or runs to a new location, upgrades add $300–$900.
- Permit fees: Included in our quotes. BC Safety Authority permit is mandatory and non-negotiable.
When does a heat pump make more sense than a new furnace? If your furnace is over 18 years old and you're replacing it regardless, run the heat pump numbers before deciding. After CleanBC rebates, a heat pump can cost the same as a new furnace while also eliminating gas bills and adding air conditioning. We'll model both at the free in-home quote — no pressure to go either direction.
How much does furnace replacement cost in BC? +
Furnace replacement in BC typically costs $3,500–$8,000 fully installed including permit. A mid-efficiency single-stage replacement runs $3,500–$4,800. A high-efficiency two-stage system is $4,500–$6,500. Top-tier modulating furnaces are $5,500–$8,000. Labour in the Lower Mainland is generally $800–$1,800 depending on complexity.
How long does furnace installation take in BC? +
A standard furnace replacement in BC typically takes 4–8 hours. Same-day installation is available for most residential replacements — you won't be without heat overnight.
Should I replace my BC furnace or switch to a heat pump? +
If your furnace is over 18 years old and you're replacing it anyway, a heat pump is worth serious consideration. After CleanBC rebates of $3,000–$6,000+, the net cost of a heat pump can be comparable to a new gas furnace — and you also get air conditioning and eliminate gas heating bills. We'll model both options at the free in-home quote.
