Heating Repair Service in Coquitlam: Furnace, Boiler & Water Heater Repair

Furnace, Boiler, or Water Heater? Find the Right Repair Service

The right repair service depends on what kind of heating equipment you have. Here's where to find detail on your specific problem:

• Hot water tank repair: no hot water, rusty water, rumbling, or a tank that's leaking. See our full guide on water heater repair for symptoms and what's actually repairable.
• Tankless water heater repair: error codes, cold water mid-shower, or reduced flow from an on-demand system.
• Electric water heater repair: tripped breakers, failed elements, or a unit that won't heat at all.
• Furnace repair: no heat, a furnace that won't stay lit, uneven heating from room to room, or a furnace that cycles on and off too often.
• Boiler repair: hydronic heating, radiant floors, and combi systems that have stopped heating properly.

If you're not sure which category your problem falls into, that's fine. Describe what's happening when you call and we'll send the right technician.

Most calls start with one of a handful of symptoms. Here's what each one usually points to:



• Furnace blowing cold air: often a failed igniter, a dirty flame sensor, or a safety switch that has shut the burner down.
• Short cycling: a furnace that turns on and off every few minutes is often overheating because of a clogged filter, or getting bad signals from a faulty thermostat.
• Uneven heating: cold rooms at one end of the house can come from blocked ducts, a weak blower, or air trapped in a boiler's radiators or baseboards.
• A boiler losing pressure: a gauge that keeps dropping usually means a leak in the loop, or a failing relief valve or expansion tank.
• Banging, rumbling or whistling: sediment in a water heater, air in hydronic lines, or a blower motor on its way out.
• A pilot light that won't stay lit: frequently a worn thermocouple, the small sensor that tells the gas valve the pilot is burning.

Some of these are a quick fix. Others, like a cracked heat exchanger, change the repair-or-replace math. Either way, the first step is a proper diagnosis, not a guess.

Anything touching a gas line, burner, pilot, or venting needs a licensed gas fitter in British Columbia. It's not a formality. A mistake here risks a gas leak or carbon monoxide exposure in your home. We're licensed for gas work ourselves, so we don't subcontract the part of the job that actually needs the license. Our heating technicians are trained to service and repair gas furnaces, boilers, and water heaters safely, and every job is done to code.

A heating emergency doesn't keep office hours, so neither does our emergency service. Our 24-hour emergency service runs every day, with emergency repairs across Coquitlam, Port Coquitlam, Port Moody, Burnaby, and New Westminster. A furnace that quits during a January cold snap or a hot water tank that fails on a Sunday morning gets the same fast and reliable heating repair as a weekday service call.

We also handle emergency plumbing service, so if a failed tank has also flooded the mechanical room, one call covers both.

Before you call, there are two quick checks any homeowner can make. Make sure the thermostat is set to heat, and that the furnace's power switch (it looks like a light switch near the unit) is on. If you smell gas, don't touch any switches. Leave the house and call FortisBC's gas emergency line from outside.

What to Expect on a Heating Service Call

The best heating repair is the one that fixes the cause, not just the symptom. Here's how a typical visit goes:

• You call and tell us what's happening. What kind of system it is, roughly how old, and what it's doing. That helps us send the right technician with the right parts.
• The technician finds the cause. On a furnace that means checking the ignition, gas pressure, flame sensor, controls, and venting. On a boiler, it's the pressure, pumps, and valves.
• You get a clear price before work starts. No hidden fees, and no repair work until you say go.
• We fix it and test it. The system runs through a full cycle to confirm it's heating properly before we leave.
• Straight advice on what's next. If a part is close to failing or the system is overdue for maintenance, we'll say so and leave the decision with you.

We've worked on home heating and plumbing in this region since 1993. That's a lot of furnaces, boilers, and water heaters, and it means your technician has likely seen your setup before. We maintain and repair the heating side of your home's HVAC system, from furnace repair services to boiler repair services. We also handle repair and installation for both space heating and water heating equipment.

Because we're a plumbing service and a licensed gas fitter under one roof, the water side and the gas side of a heating system can be handled on the same visit. That matters on a boiler, where the problem can sit in the piping, the pump, or the gas valve. We're licensed, insured, and BBB-accredited, and we back our work with a satisfaction guarantee: if something isn't right, we come back and make it right.

Repair or Replace? When a New Furnace or Water Heater Makes Sense

A single failed part on a reasonably young furnace, boiler, or water heater is usually worth fixing. An aging unit that has already needed repairs more than once, or a tank leaking from the body, usually isn't. At that point, replacing a furnace or tank is often a better use of your money than another round of repair work. When it comes to repairs or replacements, we'll give you an honest answer rather than push the more expensive option.

For water heaters, our water heater repair guide walks through the decision, and our hot water tank replacement page covers what a new tank involves. If it's time for a new furnace, our heating replacement page covers furnace replacement and furnace installation.

Furnace Repair and Maintenance Go Together

A lot of the repair work we see could have been avoided with regular furnace maintenance. A clogged filter, a dirty burner, or a boiler that hasn't been serviced in years puts strain on the whole heating system, and the failure tends to show up in the coldest week of the year. A clogged filter also hurts your indoor air quality.

Once the immediate problem is fixed, we'll tell you plainly what it would take to keep your heating system running reliably, whether that's an annual tune-up or nothing at all. Furnace repair and maintenance are two halves of the same job. Our heating maintenance page covers what a tune-up includes.

Local Heating Repair Across Coquitlam and the Tri-Cities

Our shop is on Fawcett Road in Coquitlam, so Port Coquitlam, Port Moody, Burnaby, and New Westminster are close to home for our local heating technicians. A few things about heating here shape the repairs we see:

• A long, damp heating season. Metro Vancouver heating systems tend to run from fall well into spring, rather than working hard for a few months. Long run times wear out igniters, blower motors, and filters.
• Higher neighborhoods run colder. Homes up on Westwood Plateau and Burke Mountain sit well above the valley and can see snow when the rest of the Tri-Cities gets rain. A furnace that only just keeps up lower down may fall behind up there.
• Cold snaps hit everyone at once. When an Arctic outflow brings a cold snap to the Lower Mainland, borderline furnaces and boilers tend to fail in the same few days. Getting maintenance done in the fall is the easiest way to avoid that.

Is My Furnace, Boiler, or Water Heater Worth Repairing?

Usually, yes, if it's a single failed part on a reasonably young system. An older unit with repeated problems, or one leaking from the body, is often better replaced. We'll tell you honestly which situation you're in.

Why Is My Furnace Blowing Cold Air?

First, check that the thermostat is set to heat (not just fan) and that the filter isn't clogged. If both are fine, the usual causes are a failed igniter, a dirty flame sensor, or a safety switch that has shut off the burner. Those need a technician.

Do You Offer Emergency Heating Repair?

Yes. Our emergency line runs 24 hours a day, every day, across Coquitlam, the Tri-Cities, and the Lower Mainland.

Can I Repair a Gas Furnace or Water Heater Myself?

Not the gas-connected parts. Gas work on a heating system needs a licensed gas fitter in BC. Non-gas issues, like a tripped breaker on an electric unit, are lower risk, but a misdiagnosis can still cost you more in the long run.

How Much Do Heating and Furnace Repair Costs Run?

It depends on the system and the specific failure. Furnace repair costs for a single failed part are very different from a boiler with a cracked heat exchanger. Our rates page is a good starting point, and we'll always give you a clear number before we start work, with no hidden fees.

Do You Repair All Brands?

Yes. We work on all major brands of furnaces, boilers, and water heaters, for both residential and commercial heating systems.
