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

Interesting temperature changes and the expectation of early spring can let us down as we wait until the end of the winter season. With the random weather this time of year, it’s vital to double check that your furnace service is complete and that your furnace is prepared for any weather change. Part of having and using a furnace is being familiar with 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 disclose to you what kind of efficiency you can look for from your system. If you are unaware of your AFUE, this percentage can be verified at your next furnace tune-up appointment from one of our professionals at Four Seasons Air Conditioning and Heating LLC.

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 less energy efficiency paralleled to a new furnace in the winter when your system is in use.
  • Consider your AFUE percentage in relation 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 understanding into the significance of your furnace’s AFUE. There are many things that go into selecting a new furnace or remaining with your furnace service plan. Over time still, decreased efficiency levels can significantly influence your energy usage, monthly bills and ease. Don’t ignore the AFUE rating of your furnace and consider it when determining whether it’s time for furnace replacement.
