How AFUE affects your bill

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

Curious temperature changes and the desire for early spring can mess with us as we wait until the end of the winter season. With the unpredictable weather this time of year, it’s important to double check that your furnace service is taken care of and that your furnace is set for any weather change. Part of having and operating a furnace is knowing the system and knowing when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to note 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 maintenance appointment from one of our professionals at Knoechel Heating Company.

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


  • The older your furnace is, the littler its AFUE will also be. This means not as much energy efficiency compared to a new furnace every winter when your system is in use.
  • Consider your AFUE percentage proportionate to money – if your AFUE is 75%, that means that for every $100 you use heating your home, only $75 is being used to heat your home.

Bearing in mind the age of your furnace and the possibility of overspending on your heating costs has hopefully provided some perception into the weight of your furnace’s AFUE. There are many factors that go into choosing a new furnace or remaining with your furnace service plan. Over time still, lower efficiency levels can drastically impact your energy usage, monthly bills and coziness. Don’t ignore the AFUE rating of your furnace and think of it when determining whether it’s time for furnace replacement.
