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

Strange temperature changes and the hope of early spring can mess with us as we wait until the end of the winter season. With the random weather this time of year, it’s crucial to double check that your furnace service is taken care of and that your furnace is prepared for any weather swing. Part of owning and utilizing a furnace is understanding the system and preparing for when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to recognize and can tell you what kind of efficiency you can expect from your system. If you are unaware of your AFUE, this percentage can be determined at your next furnace service appointment from one of our professionals at Air Temperature Control.

So, what does this AFUE rating suggest for you? What types 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 than with 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 use heating your home, only $75 is being used to heat your home.

Considering the age of your furnace and the potential of overspending on your heating costs has hopefully provided some insight into the significance of your furnace’s AFUE. There are many elements that go into selecting a new furnace or remaining with your furnace service plan. Over time however, smaller efficiency levels can significantly influence your energy usage, monthly bills and ease. Don’t ignore the AFUE rating of your furnace and consider it when deciding whether it’s time for furnace replacement.
