Furnace Service, AFUE and What They Mean for You in Reeds Spring

Interesting temperature changes and the desire for early spring can let us down as we wait until the end of the cold season. With the unpredictable weather this time of year, it’s important to make sure that your furnace service is complete and that your furnace is set for any weather shift. Part of owning and operating a furnace is being familiar with the system and understanding when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to recognize and can inform you what kind of effectiveness you can look for from your system. If you are unsure of your AFUE, this percentage can be verified at your next furnace tune-up appointment from one of our professionals at All Seasons Comfort Systems Inc.

So, what does this AFUE rating indicate for you? What types of things should you think on with AFUE?


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

Taking into account the age of your furnace and the likelihood of overspending on your heating costs has hopefully given some perception into the importance of your furnace’s AFUE. There are many factors that go into selecting a new furnace or staying in your furnace service plan. Over time however, decreased efficiency levels can significantly influence your energy usage, monthly bills and comfort. Don’t disregard the AFUE rating of your furnace and think of it when determining whether it’s time for furnace replacement.
