No heat, cold air, repeated cycling or an unfamiliar furnace sound? Call the Toronto line and describe exactly what the system is doing.

Useful before you call
Furnace trouble often becomes obvious at the worst time: the thermostat is calling for heat, but the house stays cold. Other warning signs include a unit that starts and stops repeatedly, air that never warms up, a blower that keeps running, new mechanical sounds or an error code on the control board.
Some causes are simple and others require trained diagnosis. Before calling, check that the thermostat is set to heat and note whether the furnace has power. Do not remove sealed panels, bypass safety switches or repeatedly reset a system that smells unusual. If you suspect a gas leak or carbon monoxide, leave the property and contact the appropriate emergency service.
A useful furnace repair call includes the furnace brand if visible, approximate age, the symptom, when it began and any recent maintenance or repair. That information helps separate a repair question from a maintenance or replacement conversation without pretending the cause can be confirmed online.

Questions before service
Possible causes range from thermostat or airflow issues to ignition, fuel or control problems. A proper diagnosis is needed before the repair can be determined.
No. Repeated resets can hide an underlying fault. Record any error code and describe the behaviour when you call.
A suspected gas or burning-electrical smell should be treated seriously. Leave the area when appropriate and contact the emergency utility or fire service before arranging ordinary HVAC service.
Share your postal code, furnace brand and approximate age if known, the symptom, any error code and when the problem started.
