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

Interesting temperature changes and the hope of 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 vital to ensure that your furnace service is complete and that your furnace is set for any weather shift. Part of possessing and operating a furnace is understanding the system and preparing for 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 expect from your system. If you are not informed of your AFUE, this percentage can be clarified at your next furnace tune-up appointment from one of our experts at Dynamic Comfort Solutions.

So, what does this AFUE rating mean for you? What kinds of things should you take into account with AFUE?


  • The older your furnace is, the smaller its AFUE will also be. This means less energy efficiency than with a new furnace every winter when your system is in use.
  • Consider your AFUE percentage in relation 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.

Taking into account the age of your furnace and the likelihood of overspending on your heating costs has hopefully provided some insight into the importance of your furnace’s AFUE. There are many factors that go into choosing a new furnace or sticking to your furnace service plan. Over time however, smaller efficiency levels can significantly impact your energy usage, monthly bills and comfort. Don’t overlook the AFUE rating of your furnace and think of it when determining whether it’s time for furnace replacement.
