Furnace Service, AFUE and What They Mean for You in Ontario

Interesting temperature changes and the hope of early spring can mess with us as we wait until the end of the cold season. With the erratic weather this time of year, it’s important to ensure that your furnace service is taken care of and that your furnace is prepared for any weather change. Part of owning and utilizing a furnace is knowing the system and understanding when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to recognize and can inform you what kind of effectiveness you can look for from your system. If you are unaware of your AFUE, this percentage can be clarified at your next furnace tune-up appointment from one of our experts at Stan's Heating, Inc .

So, what does this AFUE rating mean for you? What types of things should you take into account with AFUE?


  • The older your furnace is, the littler its AFUE will also be. This means less energy efficiency paralleled to a new furnace in the winter when your system is in use.
  • Think about your AFUE percentage in relation to money – if your AFUE is 75%, that means that for every $100 you use heating your home, only $75 is taken to heat your home.

Bearing in mind the age of your furnace and the possibility of overspending on your heating costs has hopefully offered some insight into the weight of your furnace’s AFUE. There are many things that go into selecting a new furnace or remaining with your furnace service plan. Over time still, lower efficiency levels can significantly effect your energy usage, monthly bills and coziness. Don’t ignore the AFUE rating of your furnace and consider it when deciding whether it’s time for furnace replacement.
