A furnace that struggles in the middle of an Ontario winter is stressful. Before you spend money, it helps to know whether you are dealing with a repair or a sign that your furnace has reached the end of its life.

Signs your furnace may need replacing

  • Age. Many furnaces last around 15 to 20 years, depending on the model and how well they are maintained.
  • Frequent repairs. If you are calling for service more and more often, the repair bills can add up.
  • Uneven heating. Rooms that are always too cold or too warm can point to a system that is no longer keeping up.
  • Rising energy bills. An older system may use more fuel to deliver the same heat.
  • Noises. Banging, rattling or squealing that does not go away deserves attention.

When a repair makes sense

If your furnace is relatively young and the problem is a single part, such as a thermostat, igniter or blower issue, a repair is often the sensible choice. A technician can inspect the system and explain what failed and what it will take to fix.

Safety comes first

If you notice a yellow or flickering burner flame, soot around the furnace, or a carbon monoxide alarm sounds, treat it seriously. If an alarm sounds, leave the home and call 911. Every home with a fuel-burning appliance should have working carbon monoxide alarms.

Questions to ask before you decide

  • How old is the furnace, and what is its repair history?
  • What exactly is wrong, and what will the repair involve?
  • What are my replacement options, and what would installation involve?
  • Will new equipment be the right size for my home?

We give clear, plain-language explanations so you can choose with confidence. Installation estimates are given by phone or, if needed, by visiting your property.

What a furnace inspection looks at

During an inspection, a technician typically checks the ignition and burners, the blower, the controls and thermostat, airflow, and the venting. Safety controls are tested as well. Knowing the condition of each part makes the repair-or-replace decision much clearer.

Ways to help your furnace last longer

  • Change the filter on schedule.
  • Book an annual tune-up before winter.
  • Keep the area around the furnace clear.
  • Do not ignore new noises, smells or short cycling.
