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

Interesting temperature changes and the expectation of early spring can keep us holding out as we wait until the end of the cold season. With the unpredictable weather this time of year, it’s important to ensure that your furnace service is taken care of and that your furnace is prepared for any weather swing. Part of owning and using a furnace is understanding the system and understanding when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to note and can tell you what kind of productivity you can expect from your system. If you are unaware of your AFUE, this percentage can be clarified at your next furnace maintenance appointment from one of our professionals at House of Heating Incorporated.

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 littler its AFUE will also be. This means not as much 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 devote to heating your home, only $75 is spent to heat your home.

Considering the age of your furnace and the potential of overspending on your heating costs has hopefully provided some insight into the weight of your furnace’s AFUE. There are many things that go into selecting a new furnace or sticking to your furnace service plan. Over time still, decreased efficiency levels can drastically impact your energy usage, monthly bills and coziness. Don’t disregard the AFUE rating of your furnace and think of it when choosing whether it’s time for furnace replacement.
