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

December 31, 2015

Interesting temperature changes and the hope of early spring can keep us holding out as we wait until the end of the winter season. With the unpredictable weather this time of year, it’s vital to make sure that your furnace service is complete and that your furnace is set for any weather change. Part of owning and operating a furnace is being familiar with the system and knowing when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to recognize and can inform you what kind of productivity you can anticipate from your system. If you are unaware of your AFUE, this percentage can be verified at your next furnace maintenance appointment from one of our experts at Dearing's Service & Solutions.

So, what does this AFUE rating suggest for you? What kinds of things should you consider with AFUE?


  • The older your furnace is, the lower its AFUE will also be. This means reduced energy efficiency than with a new furnace in the winter when your system is in use.
  • Compare your AFUE percentage proportionate to money – if your AFUE is 75%, that means that for every $100 you devote to heating your home, only $75 is being used to heat your home.

Considering the age of your furnace and the potential of overspending on your heating costs has hopefully given some perception into the importance of your furnace’s AFUE. There are many things that go into choosing a new furnace or staying in your furnace service plan. Over time however, smaller efficiency levels can significantly influence your energy usage, monthly bills and coziness. Don’t overlook the AFUE rating of your furnace and consider it when deciding whether it’s time for furnace replacement.
