How AFUE affects your bill

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

Strange temperature changes and the desire for early spring can mess with us as we wait until the end of the cold season. With the unpredictable weather this time of year, it’s vital to double check that your furnace service is taken care of and that your furnace is set for any weather swing. Part of possessing and utilizing 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 central measurement to recognize and can disclose to you what kind of productivity you can look for from your system. If you are unaware of your AFUE, this percentage can be determined at your next furnace tune-up appointment from one of our professionals at 1st Choice Service Group Inc.

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


  • The older your furnace is, the lower its AFUE will also be. This means less energy efficiency compared to a new furnace each winter when your system is in use.
  • Compare 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 taken to heat your home.

Bearing in mind the age of your furnace and the likelihood 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 sticking to your furnace service plan. Over time though, decreased efficiency levels can drastically effect your energy usage, monthly bills and comfort. Don’t overlook the AFUE rating of your furnace and consider it when choosing whether it’s time for furnace replacement.
