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

December 31, 2015

Interesting temperature changes and the desire for 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 crucial to make sure that your furnace service is taken care of and that your furnace is prepared for any weather shift. Part of owning and operating a furnace is knowing the system and knowing when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to know and can disclose to 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 Goode Bros AC & Heating.

So, what does this AFUE rating indicate for you? What sorts of things should you take into account with AFUE?


  • The older your furnace is, the littler its AFUE will also be. This means less energy efficiency compared to a new furnace each winter when your system is in use.
  • Consider your AFUE percentage proportionate 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 potential of overspending on your heating costs has hopefully offered some understanding into the significance of your furnace’s AFUE. There are many factors that go into selecting a new furnace or remaining with your furnace service plan. Over time though, smaller efficiency levels can radically influence your energy usage, monthly bills and ease. Don’t ignore the AFUE rating of your furnace and reflect on it when determining whether it’s time for furnace replacement.
