Furnace Service, AFUE and What They Mean for You in Cedar Rapids

Interesting temperature changes and the hope of early spring can let us down as we wait until the end of winter. With the erratic weather this time of year, it’s vital to ensure that your furnace service is taken care of and that your furnace is prepared for any weather shift. Part of having and using 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 disclose to you what kind of effectiveness you can look for from your system. If you are unaware of your AFUE, this percentage can be determined at your next furnace maintenance appointment from one of our professionals at Ilten's Incorporated.

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


  • The older your furnace is, the smaller its AFUE will also be. This means less energy efficiency paralleled to a new furnace every 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 devote to heating your home, only $75 is taken to heat your home.

Bearing in mind the age of your furnace and the likelihood of overspending on your heating costs has hopefully offered some perception into the importance 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 significantly impact your energy usage, monthly bills and ease. Don’t overlook the AFUE rating of your furnace and think of it when choosing whether it’s time for furnace replacement.
