Fast, Honest Furnace Repair Across Coquitlam
When your furnace stops working in a Coquitlam winter, every hour without heat matters. Pipes in unheated walls and crawl spaces start to freeze around −6°C — and Coquitlam cold snaps regularly hit −8 to −10°C. We dispatch a licensed technician with a fully stocked van, run a complete diagnostic, give you a flat-rate written quote before any work begins, and most repairs finish on the first visit.
We service every major furnace brand sold in BC: Lennox, Carrier, Trane, Bryant, Rheem, Goodman, Amana, York, Daikin, Napoleon, Keeprite, and American Standard. Every technician on the team holds a current Technical Safety BC gas-fitter licence — required by law in BC to work on the gas train of any appliance.
Honest diagnostics, no manufactured urgency, no upselling. If the right answer is a cheap repair, we tell you. If your 22-year-old furnace doesn't make sense to repair anymore, we tell you that too — and walk you through replacement options including the BC heat-pump rebate path.

Furnace Symptoms We Fix in Coquitlam
Eight symptoms account for over 90% of the emergency furnace calls we take across the Tri-Cities. Find yours below — we'll tell you what's likely wrong and what we'll do.
No heat at all
Likely cause: Failed igniter or flame sensor, tripped pressure switch, dead control board, gas valve fault, or the wall-mounted furnace switch was knocked off.
What we do: We diagnose with a multimeter and combustion analyzer on the first visit and carry every common ignition-side part on the van.
Furnace blowing cold air
Likely cause: Most often a dirty flame sensor failing to verify the flame, an over-temp limit switch tripping from restricted airflow, or thermostat set to ON instead of AUTO.
What we do: Five-minute flame sensor clean fixes ~30% of these calls. If it's the limit switch, we trace the airflow restriction (filter, blower wheel, return duct).
Short cycling — starts then shuts off in under 3 minutes
Likely cause: A dirty filter is the #1 cause in Coquitlam (the high-limit switch is doing its job). Other causes: blocked condensate drain on a high-efficiency unit, oversized furnace, failing pressure switch.
What we do: We test airflow static pressure and inspect the heat exchanger before assuming filter alone is the fix.
Loud bang or boom on ignition
Same-dayLikely cause: Delayed ignition — gas accumulates briefly before lighting and you get a small explosion in the burner box. Repeated delayed ignitions can crack the heat exchanger and leak CO into your supply air.
What we do: Same-day call. We clean burners, verify gas pressure to manufacturer spec, and inspect the heat exchanger with a combustion analyzer.
Screeching, grinding, or rumbling
Likely cause: Bearing failure on the blower or inducer motor, slipping belt on older systems, or a loose blower wheel.
What we do: If the motor is failing, we'll show you the amperage draw and let you choose between a motor swap and (on older systems) replacement.
Rotten-egg or sulphur smell
Same-dayLikely cause: This is mercaptan — the odorant FortisBC adds to natural gas so leaks can be detected before they reach explosive levels.
What we do: Don't troubleshoot. Leave the house, leave the doors open, call FortisBC at 1-800-663-9911 from outside. Once the supply is shut off, we handle the appliance-side repair.
Yellow or orange flame instead of blue
Same-dayLikely cause: Incomplete combustion — usually dirty burners, but can also indicate a compromised heat exchanger or improper gas pressure. Yellow flame correlates with elevated CO output.
What we do: Same-day call. Don't run the furnace until inspected. Ensure your CO alarm is working and within 5 m of every bedroom (BC Building Code requirement).
Pilot light won't stay lit
Likely cause: On older standing-pilot systems: weak thermocouple, dirty pilot orifice, or a draft. On modern systems: a failed flame sensor mimics this symptom.
What we do: We carry thermocouples and flame sensors for all common Coquitlam-installed models — typically a same-visit fix under $200.
Before You Call
5 Quick Checks That Fix ~30% of No-Heat Calls
We'd rather you spend 5 minutes on this list than $99 on a service call to find out a breaker was tripped. If none of these resolve it, then call us — we'll know it's a real fault.
- 1
Check the thermostat
Confirm it's set to HEAT (not OFF or COOL), the temperature is above current room temp, and the screen is on. If the screen is blank, replace the batteries — dead batteries cause about 1 in 10 'no heat' calls.
- 2
Check the furnace switch
Find the switch on the wall near your furnace (looks like a regular light switch, often red). Make sure it's flipped on — it gets bumped during cleaning or laundry.
- 3
Check the breaker
Open your electrical panel and find the breaker labelled FURNACE. If it's tripped (mid-position), flip it fully OFF, then back ON. If it trips again, stop and call us.
- 4
Check the gas supply
Confirm the gas shut-off valve on the pipe entering the furnace is parallel with the pipe (open). Verify other gas appliances (stove, water heater) are working — if they're also out, call FortisBC, not us.
- 5
Check the air filter
If you can't remember the last time you changed it, that's the problem. A clogged filter trips the high-limit switch and shuts the system down. Replace it and reset by turning the furnace switch off for 30 seconds, then back on.
Stop and call FortisBC if you smell gas
Rotten-egg smell near the furnace = mercaptan, the odorant added to natural gas. Leave the house, leave the doors open, call FortisBC at 1-800-663-9911 from outside. Don't flip switches, don't use your phone inside.
Why Furnaces Fail Differently in Coquitlam
Most furnace troubleshooting content is written for dry, cold-Prairie climates. Coquitlam isn't one. Four failure modes hit Tri-Cities homes harder than anywhere else in BC.
Flame sensor oxidation accelerated by humidity
The flame sensor — a small rod that confirms the flame is burning — oxidises faster in Coquitlam's consistent 75–85% relative humidity than it does in dry climates. In Calgary it lasts 3–5 years; here, 18 months. A dirty sensor causes the furnace to ignite, fail to verify the flame, and shut down. It's the single most common no-heat call we take.
Condensate drain mould and freeze
High-efficiency furnaces (90%+ AFUE) produce condensate that drains through a PVC line. In our damp shoulder seasons, mould and algae grow inside that line and clog it. In a sudden cold snap, sections in unheated crawl spaces can freeze. Either way, the pressure switch trips and the furnace shuts down.
Atmospheric river power flickers
Tri-Cities atmospheric rivers cause repeated brief power outages and voltage sags. Modern furnace control boards lock out after multiple ignition retries, and inducer-motor capacitors weaken under repeated brownout cycles. A clear pattern: the morning after a storm, our call volume doubles.
Crawl-space ductwork moisture damage
Older Coquitlam homes — particularly Maillardville and Ranch Park ranchers — run ductwork through vented crawl spaces. Coquitlam ground moisture infiltrates joints, insulation absorbs water, and you get reduced airflow plus mould pushed into living spaces every cycle. We catch this on every emergency repair before it becomes a duct-cleaning bill.

Repair or Replace? An Honest Decision Framework
We'll always quote both. Use this table as a reality check before deciding — it's the same logic we use ourselves.
| Furnace age | Repair cost | Honest answer |
|---|---|---|
| Under 10 years | Any | Repair — you have years of life left |
| 10–15 years | Under 30% of replacement | Repair |
| 10–15 years | 30–50% of replacement | Repair, but plan replacement budget |
| 15–20 years | Under 50% of replacement | Repair if first major failure |
| 15–20 years | Over 50% of replacement | Replace — better long-term value |
| 20+ years | Any over $500 | Replace — failures will cluster |
If you're leaning toward replacement, also consider whether a heat pump makes sense for your home — the BC CleanBC rebate is up to $4,000 for most households (more for income-qualified). We cover this in our heat pump vs furnace comparison for BC and the 2026 rebate guide.

No heat in your rental? Your landlord must act fast.
Loss of heat is an emergency repair under section 33 of the BC Residential Tenancy Act. After giving the landlord a reasonable opportunity to act, tenants in BC are permitted to arrange the repair themselves and deduct the cost from rent — provided they follow the procedure in the RTA.
Document every contact attempt with the landlord (text, email, voicemail). Read RTB Policy Guideline 1 for the formal procedure. Once you're authorized to proceed, we can be at your door in under 60 minutes — and we provide a tenant-receipt format the RTB accepts.

Furnace Repair FAQs — Coquitlam
How fast can you respond to a furnace emergency in Coquitlam?
Average arrival time across our Coquitlam emergency calls is under 60 minutes — including evenings, weekends, and holidays. We are a true 24/7 dispatch (a real technician picks up, not a call centre). Call +1 (447) 557 9441 any hour and we'll give you a firm ETA before we hang up.
Do you charge extra for after-hours, weekend, or holiday service?
No. We do not charge overtime, evening, weekend, or holiday surcharges. The rate at 11pm on a Sunday is the rate at 2pm on a Tuesday. We added this policy after watching homeowners delay urgent repairs because of after-hours pricing — the delay almost always made the repair more expensive.
How much does furnace repair cost in Coquitlam?
Most repairs fall between $150 and $800 in 2026. The most common fix — a flame sensor clean — is $99 service call only. Igniter replacement runs $150–$300, blower motor $400–$800, control board $450–$900, gas valve $500–$1,200, and heat exchanger $1,500+ (at which point we recommend comparing replacement quotes). Diagnostic fee is $99 and waived if you proceed with the repair.
Why is my furnace blowing cold air?
The four most common causes in Coquitlam homes: (1) dirty flame sensor — the furnace ignites, can't verify the flame, and shuts off the gas; (2) thermostat set to ON instead of AUTO, so the blower runs constantly between heat cycles; (3) tripped high-limit switch from a clogged filter restricting airflow; (4) tripped condensate pressure switch on a high-efficiency unit. We diagnose the exact cause on the first visit.
Why does my furnace keep starting and stopping (short cycling)?
Short cycling is almost always a safety limit doing its job. The #1 cause in Coquitlam is a clogged filter restricting airflow and tripping the high-limit. The #2 cause is a blocked condensate drain on a high-efficiency furnace — common in our climate because mould and algae grow in damp, mild shoulder seasons. Less common: oversized furnace, dirty burners, failing flame sensor.
Is it better to repair my furnace or replace it?
Use the 50% rule: if the repair quote is more than 50% of the cost of a comparable new install AND your furnace is over 15 years old, replacement usually wins on long-term cost. Under 15 years, repair almost always makes sense. Over 20 years, even a small repair is often a poor investment because more failures are coming. We give you both quotes and let you decide — see our furnace repair cost guide for the full breakdown.
Are you TSBC licensed to work on gas furnaces in BC?
Yes. Every technician on our Coquitlam team holds a current Technical Safety BC gas-fitter licence and Red Seal HVAC certification. By law in BC, anyone touching the gas train of a furnace must hold a TSBC gas ticket — verify your contractor's licence at technicalsafetybc.ca before any work.
Do you service Lennox / Carrier / Trane / Bryant furnaces?
Yes — and Rheem, Goodman, Amana, York, Daikin, Napoleon, Keeprite, and American Standard. Our technicians are trained on every major manufacturer's diagnostic codes and we carry brand-specific igniters, sensors, and capacitors on the van so most repairs complete on the first visit.
My furnace is making a loud banging noise — is that dangerous?
Potentially yes. A loud bang on startup is delayed ignition — gas accumulates briefly before lighting. Repeated delayed ignitions can crack the heat exchanger, which then leaks carbon monoxide into your supply air. Shut the furnace off at the wall switch, confirm your CO alarm is working, and call us same-day. Don't keep running it.
I'm renting in Coquitlam and my landlord won't fix my furnace — what are my options?
Loss of heat is an emergency repair under section 33 of the BC Residential Tenancy Act. After giving the landlord a reasonable opportunity to act, tenants are permitted to arrange the repair themselves and deduct the cost from rent — provided they follow the procedure in the RTA. Read RTB Policy Guideline 1 first, document every contact attempt with the landlord, and call us once you're authorized to proceed.
Do you offer financing for furnace repairs or replacement?
Repairs are typically paid on completion (Visa, Mastercard, debit, e-transfer). For larger repairs over $1,500 or full replacements, we offer financing through Financeit with 0% promotional plans for qualified applicants. Apply at the time of the quote — approval is usually within minutes.
Do you carry parts on your service vans?
Yes. Every van carries the most common Coquitlam-failure parts: igniters (universal and brand-specific), flame sensors, capacitors, condensate pumps, pressure switches, thermostats, control boards for Lennox/Carrier/Trane, and a stocked gas-train kit. First-visit fix rate across our last 90 days of furnace calls is over 85%.
