How AFUE affects your bill

Furnace Service, AFUE and What They Mean for You in Franklin Lakes

Strange temperature changes and the desire for 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 double check that your furnace service is complete and that your furnace is set for any weather change. Part of owning and using a furnace is being familiar with the system and knowing when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to know and can disclose to you what kind of productivity you can expect 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 experts at Total Comfort.

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 lower its AFUE will also be. This means less energy efficiency than with a new furnace each winter when your system is in use.
  • Compare your AFUE percentage in relation 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.

Bearing in mind the age of your furnace and the potential of overspending on your heating costs has hopefully given some understanding into the significance of your furnace’s AFUE. There are many things that go into picking a new furnace or remaining with your furnace service plan. Over time though, decreased efficiency levels can radically impact your energy usage, monthly bills and coziness. Don’t overlook the AFUE rating of your furnace and reflect on it when determining whether it’s time for furnace replacement.
