Pre-Winter Furnace Checklist for Orillia Homes

October 30, 2025
As the crisp air settles over Orillia and Simcoe County, the coming winter means one thing for homeowners — it is time to ensure your furnace is ready. The last thing anyone wants is to discover a malfunctioning heating system on the first freezing night of the season. Preparing your furnace before the cold hits can prevent costly repairs, save energy, and keep your home safely warm all winter long. Why a Furnace Tune-Up Matters Winters in Orillia can be harsh and unpredictable. Regular furnace maintenance ensures that every component is working efficiently and safely. Annual tune-ups reduce the risk of sudden breakdowns, improve heating performance, and help your system last longer. Neglecting your furnace until temperatures plummet often leads to emergency repairs, higher energy bills, and potential safety risks like carbon monoxide leaks. Your Pre-Winter Furnace Checklist Replace or clean the air filter. This is one of the simplest and most effective steps to keep airflow strong and energy use low. Inspect your thermostat. Confirm that it reads accurately and responds quickly to temperature adjustments. Clear supply and return vents. Keep them free from furniture, rugs, or drapes that may restrict circulation. Check your carbon monoxide detector. Replace batteries and test functionality — this is vital for safety. Inspect the outdoor intake and exhaust pipes. Remove snow, debris, or insect nests that may block ventilation. Schedule a professional inspection. A certified technician from Mr. Heat Furnace Orillia can clean burners, check gas pressure, test the heat exchanger, and verify safe operation. Frequently Asked Questions How often should I service my furnace? Once a year — ideally in the fall before consistent cold weather sets in. Can I perform maintenance myself? You can replace filters and clear vents, but internal cleaning and combustion testing should be left to professionals. What if I smell gas or see an orange flame? Turn off the system immediately and call a qualified HVAC technician. These are potential signs of unsafe combustion. Stay Warm and Worry-Free Beat the rush and schedule your furnace tune-up before the first frost.

Strange noises or unfamiliar odours coming from your furnace are never pleasant — and they are often a sign that something needs attention. Understanding what these signals mean can help you act quickly and avoid bigger repairs down the road.


Common Furnace Noises and What They Mean

  • Squealing or screeching: Often caused by a worn-out blower belt or motor bearing.
  • Banging or booming: Could be delayed ignition or expanding ductwork. Have this inspected immediately, as it can indicate a combustion issue.
  • Rattling or vibrating: Loose panels, screws, or parts inside the blower housing.
  • Clicking: Normal when the furnace starts up, but repeated clicking could mean an ignition problem.

Furnace Smells Explained

  • Dusty or burning smell: Normal the first time you turn the furnace on each season; it should fade quickly.
  • Rotten egg or sulphur smell: This indicates a possible gas leak — evacuate the home and call your gas company or Mr. Heat Furnace Orillia immediately.
  • Musty or damp odour: May indicate mould growth in ductwork or a clogged air filter.
  • Electrical or metallic smell: Can signal overheating or wiring problems.


When to Call a Professional

If noises grow louder or smells persist beyond the first few minutes of operation, it is best to have a certified technician investigate. Delaying service can lead to further damage or safety risks.
