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

Curious temperature changes and the desire for early spring can keep us holding out 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 done and that your furnace is prepared for any weather change. Part of having and operating a furnace is being familiar with the system and understanding when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to know and can disclose to you what kind of efficiency you can look for from your system. If you are unsure of your AFUE, this percentage can be verified at your next furnace tune-up appointment from one of our specialists at Air Pro Heating & Cooling LLC.

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 smaller its AFUE will also be. This means less energy efficiency compared to a new furnace in the 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 spend on heating your home, only $75 is being used to heat your home.

Bearing in mind the age of your furnace and the potential of overspending on your heating costs has hopefully given some perception into the weight of your furnace’s AFUE. There are many factors that go into choosing a new furnace or sticking to your furnace service plan. Over time still, smaller efficiency levels can radically effect your energy usage, monthly bills and comfort. Don’t ignore the AFUE rating of your furnace and reflect on it when determining whether it’s time for furnace replacement.
