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

Curious temperature changes and the desire for 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 vital to ensure that your furnace service is taken care of and that your furnace is ready for any weather swing. Part of owning and using a furnace is understanding the system and understanding when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to know and can tell you what kind of effectiveness you can expect from your system. If you are unaware of your AFUE, this percentage can be clarified at your next furnace tune-up appointment from one of our specialists at D & D Heating & AC.

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


  • The older your furnace is, the smaller its AFUE will also be. This means less energy efficiency than with a new furnace in the winter when your system is in use.
  • Compare your AFUE percentage with regard to money – if your AFUE is 75%, that means that for every $100 you use heating your home, only $75 is being used to heat your home.

Taking into account the age of your furnace and the likelihood of overspending on your heating costs has hopefully offered some insight into the significance of your furnace’s AFUE. There are many things that go into picking a new furnace or staying in 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 determining whether it’s time for furnace replacement.
