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

Interesting temperature changes and the expectation of early spring can mess with us as we wait until the end of winter. With the erratic weather this time of year, it’s vital to double check that your furnace service is done and that your furnace is ready for any weather change. Part of owning and using a furnace is understanding the system and understanding when it might require 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 productivity you can look for from your system. If you are unaware of your AFUE, this percentage can be verified 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 smaller 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 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 elements that go into choosing a new furnace or remaining with your furnace service plan. Over time though, lower efficiency levels can radically effect your energy usage, monthly bills and comfort. Don’t disregard the AFUE rating of your furnace and think of it when determining whether it’s time for furnace replacement.
