Common Furnace Problems We See in Scarborough Homes

Scarborough’s housing stock skews older, and that shapes the repairs we see. The post-war bungalows around Birch Cliff, Cliffside, and Scarborough Village often still run on original ductwork that wasn’t sized for today’s higher-efficiency furnaces, which causes short-cycling and uneven heat between floors. Two-storey homes from the 1970s and 80s in Agincourt, Wexford, and Malvern usually have second-stage gas valves and inducer motors that wear out around the 15-year mark. Townhouses in Milliken and Morningside built in the 90s tend to have mid-efficiency units that have been pushed past their service life and now need expensive parts every winter.

The most frequent calls we get from Scarborough homeowners:

• Furnace won’t start or keeps locking out, usually a flame sensor coated in carbon, a failed igniter, or a bad pressure switch. Lockouts often clear once, then return the next cold snap, which is when most homeowners finally call.
• Blowing cold air, gas valve issue, overheating limit switch, or a clogged condensate drain on high-efficiency units. The drain problem is common in finished basements where the trap dries out over summer.
• Loud bangs or rattles on startup, delayed ignition from a dirty burner, or a cracked heat exchanger which is a safety issue we shut down on the spot. Cracked exchangers leak carbon monoxide and require replacement, not repair.
• Constant cycling on and off, oversized furnace for the duct system, dirty filter, or a thermostat placed in a bad spot. Short-cycling shortens the life of every component on the unit.
• Pilot light or flame keeps going out, thermocouple failure, drafty mechanical room, or vent blockage. We’ve found dryer vents tied into furnace flues in older Scarborough basements more than a few times.
• High gas bills with no comfort, often a partially closed damper, a bad zone control board, or a furnace that’s massively oversized for the home after a renovation.

Enbridge Gas serves all of Scarborough, and most homes still run on natural gas furnaces. If you smell gas at any point, leave the house and call Enbridge first at 1-866-763-5427.

Our Repair Process

When you call, we book a two-hour arrival window, not an all-day one. The technician arrives in a stocked van with the parts that handle most common failures, so most repairs finish on the first visit.

1. Diagnostic. We test the ignition sequence, gas pressure, draft, and safety controls. Combustion analyzer readings get logged. You get a written quote before any work starts, in plain language, with the part name and the labour separated.
2. Approval. Nothing happens without your sign-off on price. If the repair doesn’t make sense on a 20-year-old unit, we’ll tell you and walk through replacement options. No high-pressure script.
3. Repair. Parts swapped, system tested through a full heat cycle, safety controls verified, and the venting checked for proper draft.
4. Cleanup and warranty. Workmanship covered for one year, parts per manufacturer terms. We leave the work area cleaner than we found it.

Furnace Repair Costs in Scarborough

Pricing depends on the part and how accessible it is. Cramped Scarborough mechanical rooms, especially in older bungalows where the furnace is jammed under a low basement ceiling, sometimes add labour time. Here’s what most repairs run:

• Diagnostic visit: $89 to $149 (waived if you proceed with the repair on the same visit, on most jobs)
• Flame sensor clean or replace: $150 to $250
• Hot surface igniter: $200 to $350
• Pressure switch: $250 to $400
• Inducer motor: $400 to $600
• Gas valve: $400 to $600
• Control board: $450 to $600
• Blower motor (variable speed): $550 to $800
• Thermostat replacement: $200 to $450 depending on smart vs basic

Cracked heat exchangers, condemned units, or anything past the 70 percent of replacement cost line moves into a different conversation. We’ll lay out repair vs replace honestly. Older Scarborough homes sometimes need duct modifications when stepping up to a high-efficiency furnace, and we factor that into the quote rather than springing it on you mid-job. If your home has been retrofitted with additions over the years, the existing ductwork may not handle the airflow a modern two-stage furnace needs, so a static pressure test is part of any replacement quote.

Emergency Furnace Repair

No heat at 11pm in February isn’t something to wait on. Our emergency line at 1-877-707-1615 runs 24/7, and we cover Scarborough seven days a week including stat holidays. After-hours calls carry a higher trip fee, but the diagnostic and repair rates stay the same as a daytime visit. We don’t pad the bill because it’s late.

If your furnace is shut down and the temperature inside is dropping below 15C, open cabinet doors under sinks on exterior walls and let a faucet drip slightly to keep pipes from freezing. Move space heaters away from anything flammable and never run a stove or oven for heat. If you smell gas, get out of the house and call Enbridge at 1-866-763-5427 first, then call us.

Why Older Scarborough Homes Need a Different Approach

A lot of the calls we take are from second or third owners of homes built between 1955 and 1985. The original gravity furnace got swapped for a forced-air mid-efficiency in the 90s, and that got swapped for a high-efficiency in the 2010s, but the ductwork is still 1960s sheet metal sized for the original system. That mismatch causes the symptoms most owners think are furnace problems: cold rooms upstairs, hot rooms in the basement, noisy returns, and a furnace that runs constantly without ever holding setpoint. We diagnose the system, not just the furnace, so the fix actually works. Sometimes the right answer is a board swap. Sometimes it’s a return-air upgrade. We tell you which.

FAQ

How fast can you get to Scarborough?

Most calls placed before noon get same-day service. Emergency no-heat calls take priority and we typically arrive within 2 to 4 hours, often sooner depending on traffic on the 401.

Are your technicians licensed?

Yes. Every technician is TSSA-certified to work on natural gas appliances in Ontario. You can verify any gas technician’s license through the TSSA gas technician registry.

Do you charge for quotes?

The diagnostic fee is $89 to $149 depending on the time and complexity. There’s no separate quote charge. You get a fixed price before any repair work starts, and on most jobs the diagnostic fee is rolled into the repair if you proceed the same visit.

What if my furnace is too old to repair?

If a repair quote crosses roughly 70 percent of replacement cost, or your furnace is 18+ years old with multiple failed components, replacement usually makes more sense. We’ll show you both numbers and let you decide. No upsell pressure.

Do you handle older Scarborough bungalows with original ductwork?

Yes, and it’s most of what we see in the older parts of Scarborough. We measure static pressure and airflow before recommending anything. If the existing ducts can carry a high-efficiency furnace properly, great. If not, we’ll quote duct modifications separately so you know exactly what you’re paying for.

Do you also service air conditioners?

Yes, full HVAC including AC. See our AC repair page for cooling service.

Do I need a permit for furnace repair in Scarborough?

Repairs don’t usually need a permit. Full furnace replacements in the City of Toronto require a gas permit, which we pull on your behalf as part of any installation job.
