Did you know that if you’re still using one of those older, low-efficiency furnaces, you could be throwing away up to 35 cents of every dollar you spent on your heating bills? That’s because older heating systems have a low-efficiency rating of 65 to 75 percent AFUE, which means they only convert 65 percent to 75 percent of the fuel while the remaining 25 to 35 percent escapes in the air.

If you’re looking to save hundreds of dollars on your annual heating bills, consider upgrading to a high-efficiency heating system. Marsh Heating and Air Conditioning us your reliable heating company in Brooklyn Park MN that offers some of the most efficient furnaces available on the market today.

What is AFUE?

Annual Fuel Utilization Efficiency (AFUE) is a measurement of the thermal efficiency of a piece of combustion equipment like a furnace, water heater, or boiler. The U.S. Department of Energy requires that all new furnaces must convert at least 80 percent of their fuel into heat. New high-efficiency heating systems typically have a minimum of 90 percent AFUE and can be as high as 98 AFUE, which use less fuel and lower your carbon footprint. Because of this great difference in fuel efficiency, a new high-efficiency furnace can allow you to get back your investment in only a few years.

Benefits of High-Efficiency Furnaces


Most high-efficiency furnaces have the ENERGY STAR® seal of approval. ENERGY STAR products are the same or better than standard products, only they use less energy. To earn the ENERGY STAR label, furnaces must meet strict energy efficiency criteria set by the US Environmental Protection Agency or the US Department of Energy. Since they use less energy, these products save you money on your electricity bill and help protect the environment by causing fewer harmful emissions from power plants; and you get the features and quality you expect.

Tax Credits

The United States government particularly offers a federal tax credit of up to 30 percent, or up to $1500 if you purchase and have a high-efficiency furnace installed in your home.

While it is true that lower efficiency furnaces are less expensive, this tax credit can make up for the price difference, should you decide to upgrade to a high-efficiency heating system.

High-Class Airflow

Compared to standard heating systems, high-efficiency furnaces are able to better circulate the air throughout the home. These new furnaces produce more consistent heating and are able to maintain a sustained temperature. This improved airflow can effectively remove impurities from the air and prevent the accumulation of mold. These factors can greatly refine the indoor environment of your home, which results in easier, healthier breathing. This alone can be the most important reason why you should invest in a high-efficiency furnace.

Better Warranty Program

As much as you’d hate it, depending on your usage, your furnace could break at some point. This is when the warranty will help you cover the cost of repair and replacement of broken parts. Though the warranty on your furnace will vary depending on the manufacturer and dealer, selecting a high-efficiency unit will give you a more extensive warranty period compared to a cheaper model. With a condensing furnace, it is especially important to have a long-term warranty on the heat exchangers.

Some manufacturers include their furnaces with a 5-year warranty on covered parts, 10-years if the product is registered online, and a lifetime warranty on the heat exchanger.

Low Operational Noise

In addition to the health and energy advantages of a new furnace, new high-efficiency systems produce much less operating noise than an older model. New energy efficient models make use of state-of-the-art materials that lessen sound, which is important in maintaining a peaceful, quiet indoor environment.
