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

Interesting temperature changes and the desire for early spring can mess with us as we wait until the end of the winter season. With the erratic weather this time of year, it’s crucial to double check that your furnace service is complete and that your furnace is set for any weather change. Part of having and operating a furnace is knowing the system and preparing for when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to know and can inform you what kind of efficiency you can anticipate from your system. If you are not informed of your AFUE, this percentage can be verified at your next furnace tune-up appointment from one of our experts at Bell Air Conditioning Inc..

So, what does this AFUE rating suggest for you? What sorts of things should you consider with AFUE?


  • The older your furnace is, the smaller its AFUE will also be. This means not as much energy efficiency compared to a new furnace each winter when your system is in use.
  • Think about 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.

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