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

Curious temperature changes and the hope of early spring can mess with us as we wait until the end of winter. With the erratic weather this time of year, it’s important to make sure that your furnace service is complete and that your furnace is ready for any weather swing. Part of possessing and utilizing a furnace is knowing the system and knowing when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to note and can tell you what kind of effectiveness you can anticipate 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 experts at Jack's Refrigeration Heating and 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 littler its AFUE will also be. This means less energy efficiency than with a new furnace in the winter when your system is in use.
  • Consider 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 being used to heat your home.

Considering the age of your furnace and the possibility of overspending on your heating costs has hopefully provided some insight into the weight of your furnace’s AFUE. There are many factors that go into picking a new furnace or remaining with your furnace service plan. Over time though, smaller efficiency levels can drastically impact your energy usage, monthly bills and comfort. Don’t ignore the AFUE rating of your furnace and think of it when choosing whether it’s time for furnace replacement.
