As the temperatures start to drop in Burlington and Hamilton, many homeowners rely on their furnaces to keep their homes warm and comfortable. But what if your furnace seems to be running non-stop? A constantly running furnace is more than just an annoyance — it could be a sign of an underlying issue that needs attention.
At Lougheed Heating & Cooling, we help local families stay comfortable year-round. Let’s look at the most common reasons your furnace might be working overtime and how to fix the problem.
1. Dirty or Clogged Furnace Filter
One of the simplest and most common causes is a dirty filter. When your furnace filter gets clogged, it restricts airflow, forcing your system to run longer to push heat through your home.
👉 Solution: Replace your furnace filter every 1–3 months for optimal efficiency.
2. Leaky Ductwork or Poor Insulation
If warm air is escaping through leaks in your ducts or poorly insulated areas, your furnace will work harder than it should. Burlington’s older homes and Hamilton’s historic houses often have drafty spots that make your furnace run longer.
👉 Solution: Seal leaks, add insulation, and schedule a professional duct inspection.
3. Thermostat Problems
Sometimes the issue isn’t with your furnace at all — it’s your thermostat. If your thermostat is misreading the temperature or malfunctioning, it can cause your furnace to stay on longer than necessary.
👉 Solution: Upgrade to a smart thermostat for accurate readings and better control of your home comfort.
4. Furnace Size or Age
If your furnace is too small for your home, it may never quite reach the desired temperature, leading to constant run cycles. On the other hand, an aging furnace naturally loses efficiency and may need more frequent repairs.
👉 Solution: If your furnace is more than 15 years old, it might be time to consider a replacement with a high-efficiency York furnace.
Why It Matters
A furnace that runs non-stop not only drives up your energy bills but also puts unnecessary wear and tear on the system. By addressing these issues early, you can avoid costly breakdowns in the middle of a cold Burlington or Hamilton winter.
