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

Interesting temperature changes and the hope of early spring can let us down as we wait until the end of the cold season. With the unpredictable weather this time of year, it’s vital to ensure that your furnace service is done and that your furnace is ready for any weather swing. Part of having and using a furnace is being familiar with the system and preparing for when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to note and can inform you what kind of productivity you can look for from your system. If you are unsure of your AFUE, this percentage can be determined at your next furnace maintenance appointment from one of our professionals at Brian’s Heating & Cooling, Inc..

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


  • The older your furnace is, the lower its AFUE will also be. This means not as much energy efficiency compared to a new furnace in the winter when your system is in use.
  • Think about your AFUE percentage proportionate to money – if your AFUE is 75%, that means that for every $100 you devote to heating your home, only $75 is spent to heat your home.

Considering the age of your furnace and the possibility of overspending on your heating costs has hopefully provided some perception into the significance of your furnace’s AFUE. There are many factors that go into selecting a new furnace or staying in your furnace service plan. Over time still, decreased efficiency levels can drastically impact your energy usage, monthly bills and ease. Don’t overlook the AFUE rating of your furnace and reflect on it when choosing whether it’s time for furnace replacement.
