Ottawa homeowners typically schedule furnace maintenance once a year in the fall before heating season, and air conditioner maintenance once a year in the spring. Annual tune-ups keep your system running efficiently, lower energy bills, and help prevent unexpected mid-winter or mid-summer breakdowns.
Most furnaces and central air conditioners last 15 to 20 years with regular maintenance. If your system is over 15 years old, needs frequent repairs, or is driving up your energy bills, replacing it is often more cost-effective than continuing to fix an aging unit.
Watch for uneven heating or cooling, rising energy bills, strange noises, weak airflow, short cycling, or a system that struggles to reach the set temperature. If you notice any of these signs, book a diagnostic visit before the problem gets worse.
