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

Interesting temperature changes and the desire for 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 make sure that your furnace service is done and that your furnace is prepared for any weather change. Part of owning and using 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 a central measurement to know 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 verified at your next furnace service appointment from one of our professionals at Ilten's Incorporated.

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


  • The older your furnace is, the lower its AFUE will also be. This means reduced energy efficiency paralleled to a new furnace each 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 being used 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 significance 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, lower efficiency levels can drastically impact your energy usage, monthly bills and ease. Don’t disregard the AFUE rating of your furnace and think of it when choosing whether it’s time for furnace replacement.
