Furnace Service, AFUE and What They Mean for You in Front Royal

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 make sure that your furnace service is done and that your furnace is ready for any weather shift. Part of possessing and operating a furnace is knowing 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 know and can tell you what kind of efficiency you can look for from your system. If you are unaware of your AFUE, this percentage can be determined at your next furnace tune-up appointment from one of our specialists at Dave's Diversified Services.

So, what does this AFUE rating suggest for you? What types of things should you take into account 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 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 spent to heat your home.

Taking into account the age of your furnace and the possibility of overspending on your heating costs has hopefully given some perception into the weight of your furnace’s AFUE. There are many things that go into selecting a new furnace or staying in your furnace service plan. Over time still, decreased efficiency levels can significantly impact your energy usage, monthly bills and coziness. Don’t disregard the AFUE rating of your furnace and reflect on it when deciding whether it’s time for furnace replacement.
