When a Furnace Problem Is a True Emergency
Not every furnace hiccup is an emergency, but some genuinely are. Treat it as urgent if you smell gas (a rotten-egg or sulphur odour), if a carbon monoxide (CO) alarm is sounding, if you see soot or scorching around the furnace, or if there is no heat at all during a cold snap with vulnerable people in the home (infants, elderly residents, or anyone with health conditions).
If you smell gas or your CO alarm is going off, do not troubleshoot. Leave the home, take everyone with you, and from outside or a neighbour's call FortisBC at 1-800-663-9911 or 911. Once you are safe and the gas utility or fire department has cleared the situation, call us at 604-359-1081 to arrange repair.
A furnace that is simply blowing cool air, short-cycling, or making an unfamiliar rattle is usually not life-threatening, but it still deserves prompt attention before a small fault becomes a no-heat night in January.
Safe Checks You Can Do Before You Call
A few simple checks resolve a surprising number of "dead" furnaces and cost you nothing. First, confirm the thermostat is set to Heat, the target temperature is above the room temperature, and the batteries (if any) are fresh. A blank or frozen thermostat screen is a common culprit.
Next, check the furnace switch. Most furnaces have a wall switch nearby that looks like an ordinary light switch — sometimes it gets flipped off by accident. Then check your electrical panel for a tripped breaker labelled for the furnace.
Look at the furnace filter. A filter so clogged it chokes airflow can trigger the high-limit safety and shut the unit down. If it is grey and matted, replace it. Finally, make sure the furnace's two condensate-related items are clear: the front panel is fully seated (a loose door trips the door switch), and there is no water pooling under the unit. If these checks do not restore heat, it is time for a technician.
Faults That Need a Certified Gas Fitter
Beyond the basics, furnace repairs involve gas, high-voltage electricity, and combustion safety — work that is regulated in BC and should be done by a licensed, Red Seal–certified gas fitter. Common professional repairs include a failed igniter or flame sensor (the furnace tries to start but will not stay lit), a faulty inducer motor, a cracked or failing heat exchanger, a stuck gas valve, a bad blower motor or capacitor, or a control board fault throwing error codes.
Many modern furnaces flash a diagnostic code on a small LED behind the access panel. If you can safely read and note the blink pattern, it helps our technician arrive prepared. But never bypass a safety switch, jump a gas valve, or run a furnace that smells of gas or is producing soot — those shortcuts risk a fire or CO exposure.
Furnaces are serviced by our parent company, CanroHeat, which runs the same Red Seal team across Greater Vancouver for furnaces, heat pumps, and water heaters.
What Emergency Repair Costs and How Fast We Come
Honest answer: furnace repair cost depends entirely on the fault. A flame sensor clean is at the low end; an igniter or inducer motor sits in the middle; a heat exchanger or control board is at the upper end. Rather than quote a number that may not fit your situation, we give a clear diagnostic finding and an exact, written price before any work begins — call 604-359-1081 for a precise quote for your furnace.
We serve Vancouver, Burnaby, Surrey, Richmond, Coquitlam, North and West Vancouver, New Westminster, and the surrounding Lower Mainland. We prioritize no-heat calls, especially for homes with infants, seniors, or medical needs. When you call, have your furnace brand, model, and any error code ready — it speeds everything up.
Preventing the Next Emergency
Most mid-winter breakdowns trace back to a fault that an annual tune-up would have caught: a weakening igniter, a dirty flame sensor, a partially blocked condensate line, or a cracking heat exchanger. A yearly furnace service in early autumn — before the heating season ramps up — is the single most effective way to avoid an emergency call.
Between services, change your filter every one to three months, keep the area around the furnace clear, and make sure your CO alarms are installed on every level and tested monthly. If you notice rising bills, uneven heat, or new noises, book a check before the cold sets in. To schedule preventive service or same-day repair, call 604-359-1081.
