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

Curious temperature changes and the desire for early spring can mess with us as we wait until the end of the cold season. With the random weather this time of year, it’s important to make sure that your furnace service is complete and that your furnace is set for any weather swing. Part of possessing 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 central measurement to note and can inform you what kind of efficiency you can look for from your system. If you are unsure of your AFUE, this percentage can be clarified at your next furnace service appointment from one of our professionals at Alltemp Comfort Services LLC.

So, what does this AFUE rating suggest for you? What types of things should you think on with AFUE?


  • The older your furnace is, the smaller its AFUE will also be. This means less energy efficiency paralleled 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 taken to heat your home.

Taking into account 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 selecting a new furnace or sticking to your furnace service plan. Over time still, smaller efficiency levels can significantly impact your energy usage, monthly bills and ease. Don’t ignore the AFUE rating of your furnace and reflect on it when determining whether it’s time for furnace replacement.
