Furnace repair in Bolton costs $150–$800 for most faults, after a $90–$150 diagnostic that comes off the bill when you approve the work. A TSSA-licensed gas technician finds the failed part, prices it in writing, and usually fixes it on that visit from parts on the truck. Call early in the day for same-day service: Bolton is a long run from our Burlington shop, up the 407 and Highway 50, and you get the real arrival window when you call.
The furnace faults we see in Bolton's subdivisions, and what each one costs
Bolton's furnaces sort by the age of the street. The subdivisions built from the 1970s through the 1990s are on Enbridge natural gas and are mostly on their second or third furnace by now, a condensing unit vented through the side wall in plastic pipe where a metal flue once went up a chimney. Houses from the 2000s onward often still run the builder's original high-efficiency furnace, and at 15 to 25 years old those are in the stretch where inducer motors, pressure switches and igniters come due. The rural edges of town, past the end of the gas main, heat with propane or electricity, which changes the parts and the checks.
Most Bolton no-heat calls trace to a short list, and the price follows the part. A flame sensor that has coated over lets the burners light and then drops them after a few seconds; cleaning or replacing it is $150–$300. A cracked hot surface igniter is $200–$450, and a draft inducer motor with worn bearings, the small fan you hear before the burners light, is $400–$900. Control boards and gas valves cost more, and both are tested before they are condemned.
Two faults are worth knowing because you can spot them yourself. On a condensing furnace the drain trap and hose fill with sludge, water backs up into the inducer housing, and the pressure switch refuses to close: you hear the small fan start, then nothing. After heavy snow or a windy night, the intake and exhaust pipes on the side wall can be buried by a drift, which shuts the furnace down for the same reason. Clearing the snow from both pipes usually brings the furnace back, while a gurgling drain needs a service visit at $150–$350.
Our repair-or-replace rule is plain: under 12 years old, repair it; past 15 years with a failed heat exchanger, put the money toward a new furnace; in between, compare the repair with half the cost of a replacement.

Furnace Repair in Bolton — FAQs
How much does furnace repair cost in Bolton?
Most repairs are $150–$800 after a $90–$150 diagnostic credited to the work. By part: flame sensor $150–$300; hot surface igniter $200–$450; pressure switch or capacitor $250–$500; draft inducer motor $400–$900; control board $500–$1,200; gas valve $500–$1,000; blower motor $500–$1,500. The figure is given to you in writing before the repair starts, and the pricing page lists the rest of our work.
Can you come to Bolton the same day?
Often, when you call in the morning and the day's board allows it, and no-heat calls in freezing weather go ahead of routine work. We will not promise a time we cannot keep. Bolton is reached by the 407 and Highway 50 from our Burlington shop, so the window we give you includes the drive. The line is answered 24/7, and night and weekend calls cost the same as weekday ones.
My furnace starts, runs for a few seconds and shuts off. What is that?
On most furnaces that pattern is the flame sensor. The burners light, the coated sensor rod fails to prove flame, and the control shuts the gas within seconds, tries again, then locks out. It is one of the least expensive repairs at $150–$300. Do not keep cycling the power to force a restart; note the flash code showing through the sight glass on the furnace door and tell us when you call.
Do you repair propane furnaces on the rural edge of Bolton?
Yes. Past the end of the Enbridge main, houses run on propane, and a propane furnace is the same appliance with different orifices and a higher gas pressure. Before you call, read the gauge on the tank: a furnace that quit with the gauge near empty needs a delivery and a relight from your supplier, not a technician. With fuel in the tank, the diagnosis runs the same way it does on natural gas.
What happens if the technician finds a cracked heat exchanger?
The furnace is shut off and tagged, because a gas technician who finds an immediate hazard is required to do that under TSSA rules. A heat exchanger costs $1,500–$3,000 to replace, and cracks typically appear on furnaces 15 or more years old, so that money is usually better spent toward a new high-efficiency furnace at $4,500–$7,500 installed. You get both figures in writing and the decision is yours.
