A furnace inspection for home insurance is rarely a condition of a standard Ontario policy on a gas-heated house — insurers generally ask the age of the heating system on the application and leave it there. Where inspections genuinely get demanded is oil heat, wood-burning appliances, and older homes with knob-and-tube wiring or a 60-amp service. What every policy quietly depends on, though, is that you maintained the system, because after a loss the adjuster asks for service records and wear and tear is an exclusion in the wording.
Every insurer writes its own policy. Treat what follows as the questions to put to your broker rather than as a description of your particular coverage.
What Ontario Insurers Actually Ask About Heating
Age, fuel, and what else is in the house. A new application or a renewal review typically asks the age of the roof, the wiring, the plumbing and the heating system, plus the primary heat source. A gas furnace is unremarkable to an underwriter; the answers that trigger follow-up are oil, wood, and occasionally a very old system in a house that has never been updated.
- Natural gas or propane furnace: normally nothing more than an age question on the application.
- Oil heat: expect questions about the tank — its age, whether it is indoors or outdoors, and its construction — and often a requirement for an inspection by a certified oil burner technician. Insurers set their own tank age limits and they vary, so ask yours before assuming anything.
- A wood stove, wood insert or a fireplace with an insert: many Canadian insurers require a WETT inspection report from a certified inspector before they will bind or renew.
- Electric baseboard or a heat pump: generally straightforward, although electrical panel capacity may come up during the conversation.
- Portable space heaters as a primary heat source: usually a decline, and reasonably so.
Rural properties north of Dundas Street in Burlington and out through Flamborough are where this comes up most often around here, because oil, propane and wood remain real primary heat sources beyond the gas mains.
The Difference Between Damage and Breakdown
A standard policy covers sudden and accidental damage, not a furnace that wore out. If a twenty-year-old blower motor finally seizes, that is maintenance rather than a claim. If a burst supply line floods the basement and destroys the furnace, that is damage, and it is the water event that triggers coverage rather than the furnace failure.
Equipment breakdown coverage is the endorsement that fills the gap. Many Ontario insurers sell it as an add-on covering mechanical or electrical breakdown of home systems, sometimes including the furnace, the air conditioner and the water heater. It is inexpensive relative to what it covers and most homeowners have no idea it is purchasable. Does home insurance cover furnace breakdown works through what is and is not typically included.
The Winter Vacancy Clause That Denies Real Claims
Leave the house in winter without meeting the policy's heating condition and a burst-pipe claim can be refused. Nearly every Ontario homeowner policy carries a condition for periods when the home is unoccupied during the heating season: either the heat is maintained and a competent person checks the home at stated intervals, or the water supply is shut off and the plumbing drained. Both the interval and the wording differ between insurers, and that detail is what decides claims.

The practical version if you go south for February: hold the thermostat no lower than 16°C, arrange for someone to actually walk through the house on the schedule your policy requires, and set up a low-temperature alert. A smart thermostat that emails you when the house drops below a threshold is the cheapest early warning available. Read the clause yourself rather than taking a neighbour's word for the number of days.
What to Keep in the File
Dated invoices, the contractor's licence details and the permit for anything that was installed. After a fire, a carbon monoxide incident or a water loss, an adjuster's questions are entirely predictable, and a folder answers them in five minutes instead of five weeks.
- The annual tune-up invoice, dated, listing what was actually performed rather than a single line reading service call.
- The company name and confirmation that the technician was TSSA-licensed. How to verify a TSSA licence sets out exactly what to ask for and how to check it.
- The permit and the municipal inspection sign-off from the original installation, because unpermitted gas work is precisely the sort of thing that complicates a claim.
- Model and serial numbers for the furnace, the air conditioner and the water heater, recorded somewhere outside the basement.
- Photographs of the mechanical room taken once a year, which take five minutes and settle arguments about condition before they start.
- Any red tag you have ever received, together with the invoice showing the correction was completed.
Red Tags, and Why They Matter to an Insurer
A red tag is a documented finding that an appliance was unsafe. When a licensed technician or the gas utility identifies an unsafe condition, the appliance is tagged — an immediate-hazard tag means it is shut down and the gas secured on the spot, while a non-immediate tag identifies a condition that must be corrected within the period stated on the tag itself. Enbridge Gas will tag an appliance during a meter or service visit for the same reasons a contractor will.
Running a tagged appliance anyway is the clearest possible evidence of knowing neglect, and it is not a position you want to occupy while an adjuster reads the file. The most common cause we encounter is a cracked heat exchanger, and on a furnace fifteen years or older a repair at $1,500–$3,000 usually argues for replacement instead. Is a cracked heat exchanger an emergency explains why it gets shut down rather than scheduled.
What an Inspection Costs and What It Should Include
A standalone furnace tune-up in the GTA runs $120–$250, and for insurance purposes the report is the part you are buying. A visit worth paying for includes a combustion analysis, an ambient carbon monoxide test, burner and flame sensor cleaning, a heat exchanger inspection, a check of the venting and combustion air, a static pressure reading across the filter, and a written record of the actual numbers.
If your insurer or broker has asked for something specific — an oil burner report, a WETT report, a letter confirming the furnace was serviced — get the exact wording of the requirement in writing and hand it to the contractor before the visit. A generic invoice frequently is not what the underwriter asked for, and a second visit costs more than the first phone call would have. What is included in a furnace tune-up sets out the standard scope.
We are TSSA-licensed and fully insured, and our invoices list the readings rather than a single line item, which is what an underwriter or an adjuster is looking for. If you need a documented heating inspection for a policy, a renewal or a real estate closing anywhere from Burlington through Hamilton, say so when you book or read what our HVAC inspection covers.
Frequently asked questions
Do I need a furnace inspection to get home insurance in Ontario?
Usually not for a gas furnace. Insurers typically ask the age of the heating system and move on. Inspections are commonly required for wood-burning appliances, where a WETT report is standard, and for oil heat, where the tank and burner are assessed. Ask your broker what your specific insurer wants before booking anything.
Will insurance cover a furnace that stops working?
A standard policy will not, because mechanical failure from age and wear is excluded. Optional equipment breakdown coverage is what pays for mechanical or electrical failure of home systems, and it is sold as an add-on by many Ontario insurers. If a covered peril such as a flood or fire destroyed the furnace, that is a different situation and normally covered.
What is a WETT inspection and do I need one?
It is an inspection of a wood-burning appliance and its chimney carried out by a certified inspector, assessing clearances, installation and condition. Many Canadian insurers require a current report before insuring a home with a wood stove or a fireplace insert. If your house has one, ask your insurer directly whether they require it and how recent it must be.
Does home insurance require me to keep the heat on in winter?
Most Ontario policies include a condition covering unoccupied periods during the heating season, requiring either maintained heat with someone checking the home at stated intervals, or the water shut off and the system drained. The required interval varies between insurers, so read your own wording before travelling rather than relying on a general rule.
Can an insurer deny a claim because the furnace wasn't serviced?
It depends on the policy wording and on what caused the loss. Lack of maintenance is not automatically fatal to a claim, but wear and tear is excluded and neglect can be argued, particularly where an appliance was tagged as unsafe and run anyway. Dated service invoices are the cheapest protection against that argument.
