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

December 31, 2015

Strange temperature changes and the expectation of early spring can keep us holding out as we wait until the end of the winter 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 prepared for any weather shift. Part of possessing and operating a furnace is understanding 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 tell you what kind of efficiency you can anticipate from your system. If you are unaware of your AFUE, this percentage can be clarified at your next furnace maintenance appointment from one of our experts at Service Max Heating & Air Conditioning.

So, what does this AFUE rating indicate for you? What types 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 in the 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 spent to heat your home.

Considering the age of your furnace and the possibility of overspending on your heating costs has hopefully offered some perception into the weight of your furnace’s AFUE. There are many elements that go into selecting a new furnace or sticking to your furnace service plan. Over time however, decreased efficiency levels can radically impact your energy usage, monthly bills and comfort. Don’t overlook the AFUE rating of your furnace and think of it when determining whether it’s time for furnace replacement.
