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

December 31, 2015

Curious temperature changes and the hope of early spring can let us down as we wait until the end of the winter season. 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 set for any weather swing. Part of possessing and utilizing a furnace is knowing the system and understanding when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to recognize and can inform you what kind of effectiveness you can expect from your system. If you are unsure of your AFUE, this percentage can be determined at your next furnace tune-up appointment from one of our specialists at Scott Temperature.

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


  • The older your furnace is, the smaller its AFUE will also be. This means not as much energy efficiency paralleled to a new furnace each winter when your system is in use.
  • Think about your AFUE percentage in relation 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 potential of overspending on your heating costs has hopefully given some insight into the importance of your furnace’s AFUE. There are many factors that go into choosing a new furnace or staying in your furnace service plan. Over time still, decreased efficiency levels can radically effect your energy usage, monthly bills and coziness. Don’t ignore the AFUE rating of your furnace and consider it when deciding whether it’s time for furnace replacement.
