Furnace repair in Burlington from ZK Mechanical costs $150–$800 for most faults, after a $90–$150 diagnostic that we credit toward the fix. Our shop is at 4145 North Service Road, so a Tyandaga or Roseland no-heat call is a local drive rather than a QEW crossing, and there's no evening, weekend or holiday premium.
Furnace Repair in Burlington — Fast, Licensed, Same-Day Service
Burlington's furnaces age by neighbourhood. Roseland, Shoreacres and Aldershot are 1950s–60s bungalows and side-splits where a 60,000 BTU furnace breathes through a single central return, and the unit we open there is usually a second- or third-generation replacement, often mid-efficiency and venting into the original masonry chimney. Tyandaga, Brant Hills and Headon Forest are 1970s–80s two-storeys whose high-efficiency furnaces are now 10 to 15 years old — exactly when inducer motors, pressure switches and control boards start to go. Millcroft, Alton Village and the Orchard run 1990s–2010s condensing furnaces on PVC vents, where a frozen condensate trap or a snow-buried vent is the usual January call.
The price is set before we start. A flame sensor cleaning or replacement is $150–$300, a hot surface igniter $200–$450, a capacitor or pressure switch $250–$500, and a draft inducer motor $400–$900; blower motors run $500–$1,500 and control boards $500–$1,200. Anything on that list is worth doing on a furnace under 12 years old. A cracked heat exchanger at $1,500–$3,000 on a 15-year-old unit is not, and we'll show you the repair-versus-replace math rather than sell a part that buys one more winter.
Two Burlington situations need a licensed eye rather than a parts swap. When a mid-efficiency furnace in a Roseland bungalow is replaced with a sidewall-vented condensing unit, the water heater is left alone on a chimney sized for two appliances, and CSA B149.1 calls for a liner or a power-vent tank so the flue gases don't condense in the masonry. North of Dundas Street, in Kilbride and Lowville, some rural homes heat with propane rather than Enbridge gas, and propane conversion kits, regulators and orifices sit within what a TSSA gas licence covers. Both are routine for us — see the furnace repair service page or book a visit.

Furnace Repair in Burlington — FAQs
How much does furnace repair cost in Burlington?
Most Burlington furnace repairs run $150–$800, plus a $90–$150 diagnostic credited if you go ahead. Common fixes like a flame sensor, igniter, or capacitor run $150–$450, while blower motors and control boards range from $500 to $1,500. The written quote lists the part, the labour and any venting work before we start, and our furnace repair cost answer breaks the numbers down part by part.
Should I repair or replace my old Burlington furnace?
Repair if the furnace is under 12 years old or the fix costs less than half of a new unit. Replace if it's past 15 and needs a heat exchanger, blower motor or control board: a new high-efficiency furnace installs for $4,300–$7,000. Burlington Hydro doesn't run its own equipment rebate; the provincial Home Renovation Savings Program applies when you pair the furnace with a heat pump. Seven warning signs lists what we look for.
Do you service furnaces in older Burlington homes with boilers?
Yes. Plains Road, Aldershot and downtown Burlington still have hot-water boilers feeding cast-iron radiators, and those calls are circulator pumps, aquastats, zone valves, waterlogged expansion tanks and pilot assemblies rather than furnace parts. A condensing boiler can replace the old unit while every radiator stays in place. Our boiler versus furnace guide explains when that's the better route.
Why does my Burlington furnace keep shutting off in a snowstorm?
Lake-effect snow drifts against the sidewall PVC vents on Millcroft and Orchard condensing furnaces, the pressure switch senses the blockage, and the furnace locks out. Clear the intake and exhaust terminations, cycle the power switch, and it usually restarts. If it locks out again with clear vents, suspect the pressure switch, a cracked vent joint or a flooded condensate trap, and it's time to book the diagnostic.
Are you TSSA-licensed for Burlington gas work?
Yes. Every ZK technician who works on a furnace holds a TSSA gas licence, which Ontario requires for any work on a natural gas or propane appliance, and we're fully insured. Ask any contractor for the licence class on their quote — refusing to show it is the clearest sign to call someone else, since unlicensed gas work is illegal in Ontario and can void a manufacturer warranty.
