No Heat in Cobourg? Start With a Few Safe Checks
If the furnace is running without warming the home, cycling on and off, or not starting, check that the thermostat is set to heat and that the set temperature is above the room temperature. Look at the furnace filter and confirm that supply vents and return grilles are open and unobstructed. From outside, you can also look for snow or debris blocking accessible intake and exhaust openings without taking the equipment apart.
Do not remove furnace panels or work on gas or electrical components. If a carbon-monoxide alarm sounds or you smell gas, leave the home and follow the emergency instructions from your gas utility or local emergency services. If a breaker trips, leave it off and arrange an assessment rather than resetting it.
When requesting furnace repair, tell Fortis when the problem began, what the thermostat shows, whether the system starts, and whether you have noticed an error code, unusual sound, or repeated cycling. A technician can then assess the thermostat call, airflow, ignition sequence, safety controls, electrical components, and other system conditions. Call (289) 688-4822 or request service for a furnace-repair assessment in Cobourg.
