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

Interesting temperature changes and the hope of 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 owning and utilizing a furnace is being familiar with 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 note and can inform you what kind of effectiveness you can expect from your system. If you are unsure of your AFUE, this percentage can be verified at your next furnace service appointment from one of our experts 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 paralleled to a new furnace each winter when your system is in use.
  • Consider your AFUE percentage in relation 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.

Bearing in mind the age of your furnace and the potential 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 choosing a new furnace or remaining with your furnace service plan. Over time though, smaller efficiency levels can radically effect your energy usage, monthly bills and coziness. Don’t ignore the AFUE rating of your furnace and reflect on it when determining whether it’s time for furnace replacement.
