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

Interesting temperature changes and the desire for early spring can mess with us as we wait until the end of the winter season. With the erratic weather this time of year, it’s important to make sure that your furnace service is done and that your furnace is ready for any weather change. Part of having and using a furnace is knowing the system and knowing when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to know and can tell you what kind of productivity you can anticipate 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 specialists at Southern Heating & Cooling Inc..

So, what does this AFUE rating indicate 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 not as much energy efficiency compared to a new furnace every winter when your system is in use.
  • Think about your AFUE percentage with regard 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.

Taking into account the age of your furnace and the possibility of overspending on your heating costs has hopefully provided some perception into the weight of your furnace’s AFUE. There are many elements that go into picking a new furnace or remaining with your furnace service plan. Over time however, smaller efficiency levels can significantly influence your energy usage, monthly bills and comfort. Don’t disregard the AFUE rating of your furnace and reflect on it when deciding whether it’s time for furnace replacement.
