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

Curious temperature changes and the expectation of early spring can let us down as we wait until the end of the winter season. With the unpredictable weather this time of year, it’s vital to double check that your furnace service is complete and that your furnace is ready for any weather shift. Part of owning and operating 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 productivity 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 compared 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 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 significance of your furnace’s AFUE. There are many things that go into choosing a new furnace or remaining with your furnace service plan. Over time still, lower efficiency levels can drastically impact 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.
