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

December 31, 2015

Interesting temperature changes and the expectation of early spring can let us down as we wait until the end of the winter season. With the unpredictable weather this time of year, it’s vital to double check that your furnace service is done and that your furnace is set for any weather shift. Part of owning and operating a furnace is understanding the system and understanding when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to note and can tell you what kind of effectiveness you can look for from your system. If you are unaware of your AFUE, this percentage can be clarified at your next furnace maintenance appointment from one of our specialists at Booneville Heating & Cooling LLC.

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 littler its AFUE will also be. This means not as much energy efficiency paralleled to a new furnace in the winter when your system is in use.
  • Compare your AFUE percentage in relation 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.

Bearing in mind the age of your furnace and the possibility of overspending on your heating costs has hopefully given some understanding 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 though, lower efficiency levels can drastically influence your energy usage, monthly bills and comfort. Don’t ignore the AFUE rating of your furnace and consider it when determining whether it’s time for furnace replacement.
