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

Curious temperature changes and the expectation of early spring can let us down as we wait until the end of winter. With the random weather this time of year, it’s important to make sure that your furnace service is taken care of and that your furnace is set for any weather swing. Part of owning and using a furnace is being familiar with the system and knowing when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to note and can disclose to 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 True Heating & Cooling.

So, what does this AFUE rating mean for you? What sorts of things should you think on with AFUE?


  • The older your furnace is, the littler its AFUE will also be. This means less energy efficiency paralleled to a new furnace every winter when your system is in use.
  • Compare your AFUE percentage proportionate to money – if your AFUE is 75%, that means that for every $100 you devote to heating your home, only $75 is being used 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 things that go into selecting a new furnace or sticking to your furnace service plan. Over time however, lower efficiency levels can drastically influence your energy usage, monthly bills and comfort. Don’t disregard the AFUE rating of your furnace and consider it when deciding whether it’s time for furnace replacement.
