Common Toronto Furnace Problems We Fix

Toronto furnaces work hard. Between November and March, your system runs almost daily, and a typical Canadian gas furnace lasts 15 to 20 years according to Natural Resources Canada. Once a unit hits the back half of that range, breakdowns become routine. Here’s what we see most often on service calls across the city:

  • Ignition and pilot failures. Hot surface igniters crack, flame sensors get coated with residue, and the burner stops lighting. This is the #1 winter no-heat call in Toronto.
  • Short-cycling. The furnace turns on and off every few minutes. Usually a clogged filter, a flame sensor issue, or an oversized unit fighting tight Toronto townhouse ductwork.
  • Blowing cold air. The blower runs but the air isn’t warm. Could be a tripped high-limit switch, a failed gas valve, or a thermostat wired wrong after a smart thermostat install.
  • Gas smell near the unit. Stop. Leave the house, then call Enbridge Gas at 1-866-763-5427 from outside. After they shut it off, we’ll come repair the line, valve, or heat exchanger.
  • Thermostat problems. Dead batteries, miswired C-wires from DIY Nest installs, or a board that won’t communicate with the furnace.
  • Blower motor and capacitor failures. A loud hum, no airflow, or a burning smell from the vents. Capacitors are cheap. Motors are the bigger fix.
  • Cracked heat exchangers. Rare but serious. We test for CO leaks during every diagnostic and shut the unit down if we find one.

Our Toronto Furnace Repair Process

We keep it simple. Call or book online, and a dispatcher confirms a 2-hour arrival window the same day in most cases. Our technician shows up in a marked van with the parts that cover roughly 80% of common Toronto furnace failures already on board, so most repairs finish in one visit.

On site, we run a full diagnostic: combustion analysis, gas pressure check, electrical test on the board and motor, and a visual on the heat exchanger and venting. You get a flat-rate quote before any work starts, no surprises after. Once you approve, we fix it, test the system through a full heat cycle, and clean up. Every repair includes a 1-month warranty on parts and labour, plus written notes on anything we’re watching for the next service. If the furnace can’t be saved, we’ll show you why and quote a replacement separately, with no pressure.

How Much Does Furnace Repair Cost in Toronto?

Toronto furnace repair pricing depends on the part, the brand, and how quickly you need a tech on site. Here’s what we typically charge in 2026:

  • Diagnostic / service call: $99 to $149, waived if you proceed with the repair.
  • Flame sensor clean or replace: $150 to $250.
  • Hot surface igniter: $250 to $400.
  • Capacitor (blower or inducer): $200 to $350.
  • Inducer motor: $450 to $750.
  • Blower motor: $600 to $1,200 depending on ECM vs. PSC.
  • Gas valve: $500 to $900.
  • Control board: $500 to $1,100.
  • Heat exchanger replacement: $1,500 to $3,500, often a sign it’s time to replace the unit.

If your furnace is over 15 years old and the quote crosses about 50% of a new install, it’s usually smarter to put that money toward a new high-efficiency unit. We’ll walk you through the math during the visit. See our furnace installation page for replacement options and pricing.

Emergency Furnace Repair in Toronto

When it drops to minus 20 in a Toronto cold snap and the furnace quits at 11 p.m., you need a real human answering the phone. We run a 24/7 emergency line at 1 (877) 707-1615 for no-heat calls across Toronto and the GTA. Most emergency dispatches reach the home within 60 to 120 minutes, depending on traffic and weather.

Before you call, try these two things: check that the furnace switch (looks like a regular light switch near the unit) is on, and confirm the thermostat has fresh batteries. If those are fine, leave the system off and call us. Don’t keep cycling power, you can damage the control board. For suspected gas leaks, call Enbridge first, then us. Read Enbridge Gas safety guidance for the full protocol.

Frequently Asked Questions

How much does furnace repair cost in Toronto?

Most Toronto furnace repairs land between $250 and $900 once parts and labour are added together. A simple igniter or flame sensor replacement is on the low end. Motor, gas valve, or board replacements push toward the higher end. Our diagnostic fee is $99 to $149 and gets waived when you proceed with the repair.

Is my furnace worth fixing or should I replace it?

If your furnace is under 12 years old and the repair is under $600, fix it. If it’s 15+ years old, has needed two or more repairs in the last two seasons, or the quote is over half the cost of a new unit, replacement usually makes more financial sense. A new high-efficiency furnace also cuts your gas bill, since older 80% AFUE units waste roughly 20 cents on every gas dollar compared to a 96% AFUE upgrade.

I smell gas near my furnace, what do I do?

Leave the house immediately. Don’t flip light switches or use your phone inside. Once outside, call Enbridge Gas at 1-866-763-5427, the 24/7 emergency line for the entire Enbridge service territory in Ontario. After Enbridge shuts the gas off and clears the home, call us at 1 (877) 707-1615 and we’ll handle the repair.
