Are Gas Furnaces Really Better for the Environment?

Find out if your furnace has green energy consumption habits.

Gas Furnace

The term “green energy” can encompass a variety of things. Whether describing the originating source of the energy, or the efficient use of said energy, the constant threat of climate change has certainly made us sensitive to it.

In the winter, our customers sometimes ask us how “green” gas furnaces are. And the answer might surprise you. Depending on when your furnace was manufactured, your gas-based system could be quite efficient. Usually anything made in the last 5 or so years has a high AFUE (Annual Fuel Utilization Efficiency) rating.

The AFUE is a percentage measured on a scale to 100, with the highest numbers indicating the best performance. Anything above 90 is great, and the most efficient models run as high as 97. That is almost totally perfect efficiency!

The result of these highly efficient units is the reduced consumption of natural gas; a fuel source which is seen as slightly controversial in terms of its “greenness.” By using it efficiently, you reduce the overall carbon footprint of your home’s system. And no matter how you slice it, reduced energy consumption is definitely green!

However, if your unit is on the older side, you are looking at AFUE ratings around 78. It’s a pretty big difference made in just a few short years, but it really adds up. Less efficient systems burn up to 20% more gas each year.

If you want to know how efficient your gas system is, or if you’re looking to upgrade to a newer model, give the pros here at G&M a call. We’ll send one of our energy professionals out to your house, where they can perform a comprehensive energy evaluation. What are you waiting for?
