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

December 31, 2015

Curious temperature changes and the expectation of early spring can let us down as we wait until the end of winter. With the erratic weather this time of year, it’s important to ensure that your furnace service is taken care of and that your furnace is ready for any weather shift. Part of having and operating a furnace is knowing the system and understanding when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to know and can tell you what kind of effectiveness you can expect from your system. If you are unsure of your AFUE, this percentage can be verified at your next furnace maintenance appointment from one of our specialists at Airmen HVAC Service.

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 spend on heating your home, only $75 is taken to heat your home.

Taking into account the age of your furnace and the potential of overspending on your heating costs has hopefully provided some perception into the significance of your furnace’s AFUE. There are many things that go into choosing a new furnace or remaining with your furnace service plan. Over time still, decreased efficiency levels can radically influence 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.
