How AFUE affects your bill

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

Curious temperature changes and the hope of early spring can mess with us as we wait until the end of the cold season. With the random weather this time of year, it’s important to ensure that your furnace service is done and that your furnace is prepared for any weather change. Part of possessing and operating 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 know and can inform you what kind of productivity you can expect from your system. If you are unsure of your AFUE, this percentage can be determined at your next furnace tune-up appointment from one of our experts at Ackerman Heating & Air Conditioning.

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


  • The older your furnace is, the lower its AFUE will also be. This means less energy efficiency compared to a new furnace in the 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 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 perception into the importance of your furnace’s AFUE. There are many things that go into choosing a new furnace or remaining with your furnace service plan. Over time however, lower efficiency levels can significantly impact your energy usage, monthly bills and coziness. Don’t disregard the AFUE rating of your furnace and consider it when deciding whether it’s time for furnace replacement.
