Furnaces can run on various different fuel sources, but natural gas is the most common in most parts of the country, including the St. Louis area. If you currently have a natural gas furnace or you’re looking to buy a new one in the near future, it’s important to understand how energy-efficiency plays a role in the operating costs of your unit. So let’s take a look at how to determine and maximize the efficiency of a natural gas furnace.

How to determine the efficiency of a natural gas furnace

The efficiency of a natural gas furnace can be determined by looking at its AFUE rating. This rating shows what percentage of fuel a furnace is able to convert into heat. In a furnace with an 85% AFUE rating, for example, 85% of the fuel that is consumed is converted to heat and the other 15% is lost. The higher the AFUE rating, the more efficient the furnace is.

In order to receive an Energy Star rating, a furnace in the northern region of the United States must have an AFUE rating of 95 percent. Along with having a properly sealed and insulated home, upgrading to an Energy Star-rated furnace can lead to great savings on your unit’s operating costs.

How to maximize the efficiency of your current natural gas furnace

In order to maximize the efficiency of your natural gas furnace, it takes more than properly installing a unit with a high efficiency rating. You must also take good care of your furnace throughout its operating life. Three of the best ways you can do this are:
