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

December 31, 2015

Curious temperature changes and the expectation of early spring can mess with us as we wait until the end of winter. 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 set for any weather shift. Part of possessing and utilizing a furnace is being familiar with the system and knowing when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to know and can disclose to you what kind of productivity you can expect from your system. If you are not informed of your AFUE, this percentage can be verified at your next furnace maintenance appointment from one of our experts at KDM Service Corporation.

So, what does this AFUE rating indicate 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 not as much energy efficiency compared to a new furnace each 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 spend on heating your home, only $75 is spent to heat your home.

Taking into account the age of your furnace and the likelihood of overspending on your heating costs has hopefully given some understanding into the significance of your furnace’s AFUE. There are many things that go into choosing a new furnace or remaining with your furnace service plan. Over time however, lower efficiency levels can drastically impact your energy usage, monthly bills and ease. Don’t overlook the AFUE rating of your furnace and consider it when determining whether it’s time for furnace replacement.
