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

Interesting temperature changes and the hope of early spring can mess with us as we wait until the end of the winter season. With the erratic weather this time of year, it’s important to ensure that your furnace service is done and that your furnace is prepared for any weather swing. Part of possessing and using a furnace is being familiar with the system and knowing when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to note and can inform 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 maintenance appointment from one of our specialists at McCune Heating & Cooling.

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 reduced energy efficiency than with a new furnace in the winter when your system is in use.
  • Consider 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 being used to heat your home.

Considering the age of your furnace and the likelihood of overspending on your heating costs has hopefully provided some insight into the significance of your furnace’s AFUE. There are many elements that go into selecting a new furnace or staying in your furnace service plan. Over time though, smaller efficiency levels can drastically effect your energy usage, monthly bills and coziness. Don’t ignore the AFUE rating of your furnace and reflect on it when deciding whether it’s time for furnace replacement.
