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

Strange temperature changes and the desire for 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 important to double check that your furnace service is done and that your furnace is prepared for any weather swing. Part of having and utilizing a furnace is understanding the system and knowing when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to recognize and can tell you what kind of efficiency you can anticipate from your system. If you are unaware of your AFUE, this percentage can be determined at your next furnace maintenance appointment from one of our experts 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 each winter when your system is in use.
  • Consider your AFUE percentage proportionate to money – if your AFUE is 75%, that means that for every $100 you spend on heating your home, only $75 is taken to heat your home.

Considering the age of your furnace and the potential of overspending on your heating costs has hopefully given some understanding into the significance of your furnace’s AFUE. There are many factors that go into choosing a new furnace or remaining with your furnace service plan. Over time though, 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 determining whether it’s time for furnace replacement.
