Furnace Service, AFUE and What They Mean for You in Grand Prairie

December 31, 2015

Curious temperature changes and the desire for early spring can mess with us as we wait until the end of the cold season. With the erratic weather this time of year, it’s important to double check that your furnace service is taken care of and that your furnace is set for any weather change. Part of having and using a furnace is knowing 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 know and can inform you what kind of effectiveness you can look for from your system. If you are unaware of your AFUE, this percentage can be verified at your next furnace service appointment from one of our experts at Bon Air Service Company.

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


  • The older your furnace is, the smaller its AFUE will also be. This means less energy efficiency than with a new furnace every 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 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 perception into the importance of your furnace’s AFUE. There are many things that go into selecting a new furnace or sticking to your furnace service plan. Over time though, decreased efficiency levels can drastically influence your energy usage, monthly bills and comfort. Don’t overlook the AFUE rating of your furnace and consider it when deciding whether it’s time for furnace replacement.
