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

Strange temperature changes and the hope 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 vital to ensure that your furnace service is taken care of and that your furnace is set for any weather swing. Part of owning and using a furnace is understanding the system and preparing for when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to know and can inform you what kind of effectiveness you can look for from your system. If you are not informed of your AFUE, this percentage can be clarified at your next furnace service appointment from one of our professionals at Guidry's Air Conditioning & Refrigeration Service.

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


  • The older your furnace is, the littler its AFUE will also be. This means reduced energy efficiency paralleled to a new furnace every winter when your system is in use.
  • Compare your AFUE percentage proportionate to money – if your AFUE is 75%, that means that for every $100 you use heating your home, only $75 is taken to heat your home.

Considering 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 elements that go into picking a new furnace or sticking to your furnace service plan. Over time though, decreased efficiency levels can significantly impact your energy usage, monthly bills and coziness. Don’t ignore the AFUE rating of your furnace and consider it when determining whether it’s time for furnace replacement.
