If your furnace seems to run constantly but your home still feels chilly, it’s not your imagination. During Saskatchewan winters, heating systems often face extreme workloads—sometimes because of weather, sometimes because of preventable issues. Here’s why your furnace might be overworked and what you can do about it.
Your Filters Are Clogged or Old
Dirty filters restrict airflow, forcing the blower motor to work longer to deliver the same amount of heat. Change them every one to three months, especially when pets or renovations add dust.
Leaky Ductwork Wastes Heat
A 15 percent leak in your duct system can raise energy use by up to 30 percent (NRCan, 2024). Pro Service Mechanical offers duct sealing and testing for older homes throughout Saskatoon.
Thermostat Issues Throw Off System Control
If your thermostat is in direct sunlight or near a draft, it can misread temperatures and keep the furnace running. Smart thermostats eliminate guesswork by tracking usage and learning your patterns.
Poor Insulation or Air Leaks Are the Culprit
Even a new furnace can’t keep up if your home leaks heat. Adding attic insulation or sealing basement rim joists will lighten the load on your system and cut your gas bill.
The Furnace Itself Needs Service or Replacement
Older units lose efficiency over time as heat exchangers and burners degrade. If your furnace is 15+ years old, consider a modern high-efficiency model that can save up to 20 percent on fuel costs (energy.gov, 2024).
A furnace that runs too hard isn’t just inefficient—it’s a warning sign. With regular maintenance and home improvements, you can restore comfort and reduce energy use.
