Furnace Service, AFUE and What They Mean for You in Metro Atlanta

Curious temperature changes and the desire for early spring can mess with us as we wait until the end of winter. With the erratic weather this time of year, it’s vital to double check that your furnace service is done and that your furnace is prepared for any weather shift. Part of possessing and utilizing a furnace is knowing the system and understanding when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to know and can disclose to you what kind of effectiveness you can expect from your system. If you are not informed of your AFUE, this percentage can be clarified at your next furnace tune-up appointment from one of our professionals at ACS Inc.

So, what does this AFUE rating indicate for you? What sorts of things should you take into account 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 in relation to money – if your AFUE is 75%, that means that for every $100 you devote to heating your home, only $75 is being used 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 insight into the importance of your furnace’s AFUE. There are many elements that go into choosing a new furnace or sticking to your furnace service plan. Over time however, smaller efficiency levels can drastically impact your energy usage, monthly bills and coziness. Don’t disregard the AFUE rating of your furnace and reflect on it when determining whether it’s time for furnace replacement.
