Furnace installation and replacement in Langley: costs, permits and what to ask
Is your furnace repeatedly breaking down, or are you comparing quotes for a new heating system? This guide helps Langley homeowners understand the questions to ask before choosing repair or replacement. Valley Home Fix provides information and potential introductions to independent tradespeople; it does not install furnaces or issue quotes.
Repair the furnace or replace it?
Age alone does not determine whether your furnace needs replacement. A qualified professional should diagnose the fault and assess safety before you commit to a new unit. Ask for a repair estimate and compare it with a written replacement quote. Consider how frequently the furnace needs repairs, whether it heats the home evenly, and whether a newer system could meaningfully improve efficiency.
Enercare's BC furnace guidance describes roughly 15 years as an average furnace lifespan and flags frequent repairs and declining efficiency as factors to weigh. That is a provider's general guidance, not an expiration date or a mandatory replacement threshold. There is no universal “$5,000 rule” that can decide every home's repair-versus-replace choice.
For troubleshooting and published service-call rates, see our furnace repair in Langley guide. If the furnace is blowing cold air, begin with the safe first-checks guide.

Do you need a gas permit in Langley?
Technical Safety BC's homeowner gas permit guidance says gas permits are required for furnace installation or replacement, gas piping and vent work. If you hire a licensed contractor, the contractor applies for the permit; ask who is responsible and confirm the permit is in place before work begins. The issuing authority may be Technical Safety BC or the local municipality depending on the address. City of Langley and Township of Langley homeowners should confirm the applicable authority for their property.
Eligible homeowners may be able to apply for certain homeowner gas permits themselves, subject to restrictions described by Technical Safety BC. Inspection requirements also apply. Technical Safety BC says to request at least one inspection within 180 days of the permit being issued, with inspections at appropriate construction stages and after completion. Don't assume that an installer quote automatically includes every inspection or approval.
Compare furnace installation quotes carefully
Ask each company to explain these items in writing:
- Equipment and sizing: proposed make/model, efficiency rating, capacity, and how the heating load was assessed instead of simply copying the old furnace size.
- Existing system: whether ductwork, return air, electrical connections, condensate handling and venting need modification.
- Permit and inspection: who applies, which authority handles the permit, and who coordinates inspections.
- Full scope: equipment, labour, old-furnace removal, disposal, thermostat, possible upgrades, taxes and any exclusions.
- Accountability: gas contractor licensing information, written warranty terms, completion schedule and payment milestones.
Don't choose solely on the lowest advertised starting price. A quote that omits venting changes, permit costs or disposal may not be comparable to a complete quote.
Should you also consider a heat pump?
For some homes, a heat pump or hybrid system may be worth comparing against replacing a gas furnace like-for-like. Evaluate cold-weather performance, existing ductwork, electrical capacity, and total cost. Incentives change: see our BC heat pump rebates guide and confirm eligibility with the program before relying on a rebate.
Frequently asked questions
How much is furnace replacement in Langley?
There isn't a universal Langley price. The BC examples above range by provider, model and installation scope. Request itemized local quotes rather than treating any published range as a firm offer.
How long does a gas furnace usually last?
Enercare uses about 15 years as an average lifespan in its BC guidance. Actual condition, maintenance history, safety and repair costs matter more than age alone.
Who arranges a replacement permit?
Technical Safety BC says a hired licensed contractor applies for the gas permit. Ask which authority issues it for your Langley address and who arranges inspections.
Should I repair or replace a furnace that still runs?
Get a diagnosis, compare written repair and replacement estimates, and assess safety, recurring breakdowns, efficiency and comfort. Don't replace a working furnace solely because of an unsupported rule of thumb.
What is the first step before signing an installation quote?
Confirm contractor qualifications, written equipment specifications, sizing approach, permit responsibility, installation scope and warranty details.
