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

Strange temperature changes and the expectation of early spring can mess with us as we wait until the end of winter. With the random weather this time of year, it’s crucial to make sure that your furnace service is done and that your furnace is set for any weather shift. Part of possessing 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 an important measurement to know and can disclose to you what kind of effectiveness you can expect 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 specialists at Gee & Missler Heating & Air Conditioning.

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


  • The older your furnace is, the lower its AFUE will also be. This means less energy efficiency compared to a new furnace in the 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 spend on 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 provided some perception into the significance of your furnace’s AFUE. There are many things that go into picking a new furnace or remaining with your furnace service plan. Over time though, decreased efficiency levels can drastically effect your energy usage, monthly bills and comfort. Don’t disregard the AFUE rating of your furnace and consider it when deciding whether it’s time for furnace replacement.
