Furnace Service, AFUE and What They Mean for You in Napoleon and Northwest Ohio

Strange temperature changes and the expectation 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 taken care of and that your furnace is prepared for any weather shift. Part of having and using a furnace is being familiar with the system and understanding when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to note and can tell you what kind of effectiveness you can anticipate from your system. If you are unsure of your AFUE, this percentage can be determined at your next furnace maintenance appointment from one of our professionals at Von Deylen Plumbing & Heating Inc..

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


  • The older your furnace is, the lower its AFUE will also be. This means not as much energy efficiency compared 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 devote to heating your home, only $75 is taken to heat your home.

Considering the age of your furnace and the potential of overspending on your heating costs has hopefully provided some insight into the importance of your furnace’s AFUE. There are many elements that go into selecting a new furnace or remaining with your furnace service plan. Over time still, decreased efficiency levels can radically influence your energy usage, monthly bills and comfort. Don’t ignore the AFUE rating of your furnace and think of it when deciding whether it’s time for furnace replacement.
