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

Curious temperature changes and the expectation 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 vital to double check that your furnace service is taken care of and that your furnace is prepared for any weather change. Part of having and using a furnace is knowing the system and understanding when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to note and can disclose to you what kind of efficiency you can look for from your system. If you are unsure of your AFUE, this percentage can be determined at your next furnace service appointment from one of our professionals at Woody's Sudden Service Inc.

So, what does this AFUE rating indicate for you? What types of things should you think on with AFUE?


  • The older your furnace is, the lower its AFUE will also be. This means less energy efficiency paralleled to a new furnace each 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 spend on heating your home, only $75 is spent to heat your home.

Taking into account the age of your furnace and the likelihood of overspending on your heating costs has hopefully given some perception into the weight of your furnace’s AFUE. There are many factors that go into choosing a new furnace or remaining with your furnace service plan. Over time however, decreased efficiency levels can radically effect your energy usage, monthly bills and comfort. Don’t overlook the AFUE rating of your furnace and think of it when deciding whether it’s time for furnace replacement.
