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

Interesting temperature changes and the desire for 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 done and that your furnace is ready for any weather change. Part of owning and utilizing a furnace is understanding 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 tell 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 professionals at Stan's Heating, Inc .

So, what does this AFUE rating indicate 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 reduced energy efficiency paralleled to a new furnace in the winter when your system is in use.
  • Think about your AFUE percentage with regard 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 potential of overspending on your heating costs has hopefully offered some understanding 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 drastically effect your energy usage, monthly bills and comfort. Don’t ignore the AFUE rating of your furnace and reflect on it when deciding whether it’s time for furnace replacement.
