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

Curious temperature changes and the expectation of early spring can keep us holding out as we wait until the end of the winter season. 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 shift. Part of having and utilizing a furnace is knowing the system and preparing for when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to recognize and can disclose to you what kind of efficiency you can expect from your system. If you are not informed of your AFUE, this percentage can be verified at your next furnace maintenance appointment from one of our experts at Garoken Energy Co. Inc..

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


  • The older your furnace is, the littler its AFUE will also be. This means not as much energy efficiency compared to a new furnace each winter when your system is in use.
  • Think about 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 insight into the importance of your furnace’s AFUE. There are many things that go into picking a new furnace or sticking to your furnace service plan. Over time though, smaller efficiency levels can drastically influence your energy usage, monthly bills and comfort. Don’t disregard the AFUE rating of your furnace and consider it when determining whether it’s time for furnace replacement.
