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

Strange temperature changes and the hope of early spring can keep us holding out as we wait until the end of the cold season. With the random weather this time of year, it’s crucial to double check that your furnace service is done and that your furnace is prepared for any weather shift. Part of possessing and operating a furnace is being familiar with the system and understanding when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to note and can tell you what kind of effectiveness you can look for from your system. If you are not informed of your AFUE, this percentage can be determined at your next furnace maintenance appointment from one of our experts at Superior Comfort Systems.

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 every winter when your system is in use.
  • Think about your AFUE percentage proportionate to money – if your AFUE is 75%, that means that for every $100 you devote to heating your home, only $75 is spent to heat your home.

There are many elements that go into selecting a new furnace or staying in your furnace service plan. Over time still, smaller efficiency levels can radically effect your energy usage, monthly bills and coziness.
