Why furnace maintenance matters
Ontario furnaces work hard through long heating seasons. Regular maintenance provides an opportunity to inspect operation, clean or service accessible components where required, check airflow and identify developing issues before the coldest weather.
What professional furnace maintenance can include
Service can include filter and airflow review, blower operation, ignition and controls, burners, venting, safety controls, thermostat operation and overall heating performance. The exact work depends on the furnace and its condition.
Maintenance is not the same as repair
If the furnace is already failing to heat, short cycling, making new noises or showing another active fault, diagnosis and repair may be needed rather than routine maintenance alone.
