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

December 31, 2015

Strange temperature changes and the hope of early spring can mess with us as we wait until the end of the cold season. With the unpredictable weather this time of year, it’s crucial to make sure that your furnace service is done and that your furnace is set for any weather shift. Part of possessing and utilizing a furnace is knowing the system and understanding when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to know and can tell you what kind of efficiency you can anticipate 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 Farris Heating & Air.

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 lower its AFUE will also be. This means reduced energy efficiency paralleled to a new furnace in the winter when your system is in use.
  • Consider 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.

Considering the age of your furnace and the possibility of overspending on your heating costs has hopefully provided some perception into the importance of your furnace’s AFUE. There are many elements that go into selecting a new furnace or sticking to your furnace service plan. Over time still, smaller efficiency levels can significantly impact your energy usage, monthly bills and ease. Don’t disregard the AFUE rating of your furnace and think of it when deciding whether it’s time for furnace replacement.
