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

December 31, 2015

Strange temperature changes and the expectation of early spring can let us down as we wait until the end of the cold season. With the unpredictable weather this time of year, it’s important to make sure that your furnace service is taken care of and that your furnace is set for any weather swing. Part of possessing and operating a furnace is understanding the system and preparing for when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to note and can tell you what kind of productivity you can look for 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 Air Service Co..

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.
  • Consider 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 significance 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, smaller efficiency levels can drastically impact your energy usage, monthly bills and coziness. Don’t ignore the AFUE rating of your furnace and consider it when choosing whether it’s time for furnace replacement.
