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

December 31, 2015

Strange temperature changes and the expectation of early spring can mess with us as we wait until the end of winter. With the erratic weather this time of year, it’s vital to double check that your furnace service is taken care of and that your furnace is prepared for any weather change. Part of having and using a furnace is understanding the system and understanding when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to know and can tell you what kind of effectiveness you can expect from your system. If you are not informed of your AFUE, this percentage can be determined at your next furnace service appointment from one of our experts at Freed Heating & Air Conditioning.

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


  • The older your furnace is, the smaller its AFUE will also be. This means reduced energy efficiency paralleled to a new furnace every 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.

Bearing in mind the age of your furnace and the likelihood of overspending on your heating costs has hopefully provided some understanding into the importance of your furnace’s AFUE. There are many factors that go into picking 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 ease. Don’t overlook the AFUE rating of your furnace and think of it when determining whether it’s time for furnace replacement.
