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

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 erratic weather this time of year, it’s vital to double check that your furnace service is done and that your furnace is ready for any weather change. Part of possessing and utilizing a furnace is understanding 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 Heating and Air Conditioning.

So, what does this AFUE rating mean for you? What kinds of things should you take into account with AFUE?


  • The older your furnace is, the smaller its AFUE will also be. This means less energy efficiency compared to a new furnace every winter when your system is in use.
  • Compare your AFUE percentage with regard 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.

Considering the age of your furnace and the likelihood of overspending on your heating costs has hopefully given 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 however, smaller efficiency levels can drastically impact your energy usage, monthly bills and coziness. Don’t overlook the AFUE rating of your furnace and consider it when determining whether it’s time for furnace replacement.
