Furnace Service, AFUE and What They Mean for You in Excelsior Springs

December 31, 2015

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 unpredictable weather this time of year, it’s vital to double check that your furnace service is complete and that your furnace is ready for any weather change. Part of having and using a furnace is knowing the system and knowing when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to note and can tell you what kind of efficiency you can look for from your system. If you are not informed of your AFUE, this percentage can be verified at your next furnace tune-up appointment from one of our experts at Colvin's Heating and Cooling.

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


  • The older your furnace is, the smaller its AFUE will also be. This means less energy efficiency compared to a new furnace each winter when your system is in use.
  • Compare 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.

Taking into account the age of your furnace and the potential of overspending on your heating costs has hopefully provided some perception into the weight of your furnace’s AFUE. There are many elements that go into choosing a new furnace or sticking to your furnace service plan. Over time still, decreased efficiency levels can significantly impact your energy usage, monthly bills and ease. Don’t disregard the AFUE rating of your furnace and consider it when determining whether it’s time for furnace replacement.
