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

Curious temperature changes and the desire for early spring can let us down as we wait until the end of the cold season. With the erratic weather this time of year, it’s important to ensure that your furnace service is taken care of and that your furnace is prepared for any weather swing. Part of having and utilizing a furnace is being familiar with the system and preparing for when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to note and can inform you what kind of effectiveness you can anticipate from your system. If you are unsure of your AFUE, this percentage can be verified at your next furnace maintenance appointment from one of our professionals at Air-Right Energy Design, 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 littler its AFUE will also be. This means reduced 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 devote to heating your home, only $75 is being used to heat your home.

Considering the age of your furnace and the possibility of overspending on your heating costs has hopefully offered some understanding into the importance of your furnace’s AFUE. There are many things that go into selecting a new furnace or remaining with your furnace service plan. Over time however, smaller efficiency levels can radically effect your energy usage, monthly bills and comfort. Don’t ignore the AFUE rating of your furnace and reflect on it when deciding whether it’s time for furnace replacement.
