Furnace Repair · Caledon, OntarioFurnace Repair in Caledon
Furnace repair in Caledon costs $150–$450 for most faults, after a $90–$150 diagnostic that comes off the bill when you approve the work. The first thing we ask is what the furnace burns: natural gas in Bolton and the village centres, propane on most rural roads, and the answer changes what we check first. Caledon is the far end of our service area, roughly an hour's drive from the Burlington shop, so a same-day visit depends on when you call and we give you the real window on the phone.
Gas and propane furnace repair from Bolton to the rural concessions
Bolton is the straightforward half of the town. The subdivisions there are on Enbridge Gas, and the furnaces in them are mostly condensing units from the 1990s through the 2010s that fail in a familiar order: a flame sensor coated in oxide ($150–$300), a cracked hot surface igniter ($200–$450), a pressure switch or capacitor ($250–$500), then the draft inducer motor ($400–$900). Each of those is normally a one-visit repair. Our Bolton furnace repair page covers those streets in more detail.
Past the gas mains, the same furnace runs on propane with a conversion kit, and propane adds faults a town furnace never has. A tank that has run low in a cold snap cannot vaporize enough fuel to hold burner pressure, so the furnace lights, drops out and locks itself out; an iced-over regulator vent does the same thing. Check the gauge on the tank before you call, because a delivery fixes the first problem and a technician cannot. When the tank is fine, we measure gas pressure at the furnace with the burners firing and confirm the propane orifices and valve spring were fitted, since a furnace left on natural-gas parts over-fires, soots the heat exchanger and makes carbon monoxide.
Open lots and long laneways cause the other rural calls. Wind packs snow against the sidewall intake and exhaust, the pressure switch reads a blocked vent and the furnace stops, and clearing the pipes is often the whole repair (what to do when snow blocks the furnace vent). Power cuts on rural Hydro One lines bring their own fault: a furnace run from a portable generator can spin the fan and still refuse to hold a flame, because the flame sensor needs a properly bonded neutral to read. Large estate homes add long duct runs and zone dampers, and when too many zones close at once the furnace overheats and trips its high-limit switch, which looks like a furnace fault and is an airflow one.
Across every fuel, most furnace repairs run $150–$800 all in. A blower motor is $500–$1,500 depending on whether it is an ECM or a PSC type, and a cracked heat exchanger at $1,500–$3,000 on a furnace past 15 years is money better put toward a new furnace in Caledon. If a carbon monoxide alarm sounds, leave the house and call 911 before you call us; propane is heavier than air and pools in basements, so if you smell it, get out and phone your supplier's emergency number from outside. Oil burners fall under a separate TSSA certificate from gas, so tell us on the phone if yours burns oil. For the rest of our work in town see the Caledon service area page, or book a furnace diagnostic.

Furnace Repair in Caledon — FAQs
How much does furnace repair cost in Caledon?
Most repairs land between $150 and $450, and the full range is $150–$800. A flame sensor is $150–$300, an igniter $200–$450, a pressure switch or capacitor $250–$500 and an inducer motor $400–$900. The diagnostic is $90–$150 and is credited when you approve the repair. Propane and natural gas furnaces share the same parts, so the bands are the same, and you get the exact figure in writing before any part goes in.
Do you repair propane furnaces in rural Caledon?
Yes. The TSSA gas licence covers propane as well as natural gas, and propane furnaces are a large share of the calls from the concessions. Tell us the tank level when you phone. The tank and its regulators usually belong to your propane supplier, so a fault on that side is theirs to fix; everything from the house line to the burners is ours, including the conversion parts and the pressure setting.
Can you come out to Caledon the same day?
Often, not always. A call from Bolton or the southern villages that reaches us in the morning is usually seen that day; a late-afternoon call from a northern concession during a cold snap may be the next morning. The truck comes up from Burlington by the 407, the 410 and Highway 10, and we tell you the real window instead of a hopeful one. Say so if there is an infant, a senior or a medical need in the house.
My furnace quit after a power outage. What should I check?
Switch the furnace off at its wall switch for 30 seconds and back on to clear a lockout, check the breaker, and look at the sidewall vent pipes for snow or ice. If the house is on a portable generator and the furnace runs its fan but will not stay lit, suspect the generator's neutral bonding before the furnace. If it still will not fire once utility power is back, call for a diagnostic.
Is it safe to keep resetting a furnace that shuts off?
Once, yes; all night, no. A furnace that locks out is protecting itself. Stop and call if you smell gas or propane, see soot around the burner door, notice a yellow flame, or a carbon monoxide alarm sounds. Ontario's Hawkins-Gignac Act requires a working CO alarm near sleeping areas in any home with a fuel-burning appliance, so test yours today. Our furnace repair page lists the symptoms that need a technician.
