Furnace Service, AFUE and What They Mean for You in San Angelo

Curious temperature changes and the hope of early spring can keep us holding out as we wait until the end of winter. With the unpredictable weather this time of year, it’s vital to make sure that your furnace service is complete and that your furnace is ready for any weather shift. Part of owning and utilizing a furnace is being familiar with the system and preparing for when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to recognize and can inform you what kind of productivity you can anticipate from your system. If you are unsure of your AFUE, this percentage can be clarified at your next furnace tune-up appointment from one of our professionals at Air-Dynamics Inc.

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


  • The older your furnace is, the smaller its AFUE will also be. This means not as much energy efficiency paralleled to a new furnace in the winter when your system is in use.
  • Consider 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 taken to heat your home.

Bearing in mind the age of your furnace and the possibility of overspending on your heating costs has hopefully provided some understanding into the importance of your furnace’s AFUE. There are many factors that go into choosing a new furnace or remaining with your furnace service plan. Over time however, decreased efficiency levels can drastically impact your energy usage, monthly bills and ease. Don’t disregard the AFUE rating of your furnace and consider it when determining whether it’s time for furnace replacement.
