Do New Windows Really Help With Heating and Cooling Costs

Window replacement companies often claim that new windows can lower heating and cooling costs. Is this true?

According to the U.S. Department of Energy, “heat gain and heat loss through windows are responsible for 25%–30% of residential heating and cooling energy use.” The DOE website article also states, “it’s important to choose the most efficient windows you can afford that work best in your climate.”

So, to answer your original question: yes, windows help with heating and cooling costs. Here are some tips for picking the right window for your climate and budget.

Tips for Selecting Energy-Efficient Windows

Of course, there are some things you can do to make your current windows more efficient. Consider adding caulk and weatherstripping. Use window coverings that help increase efficiency. Also, consider using awnings or overhangs to create additional shade on your home during the summer.

However, if it’s time to replace your windows, here are some tips.

Look for the Energy Star label.

The National Fenestration Rating Council (NFRC) runs tests on windows to measure performance. Those products with a specific energy performance rating are given an Energy Star label. At a minimum, look for replacement windows with this designation.

The Midwest experiences extreme cold. The DOE recommends gas-filled windows with Low-E coatings for this type of climate. The government agency further recommends that you choose a low U-factor (the rate at which a window conducts non-solar heat flow) for harsh Midwestern winters.

Unfortunately, the Midwest also experiences extreme heat. If you are most concerned with reducing your cooling bills, select windows with coatings designed to reduce heat gain. Specifically, look for a low solar heat gain coef­ficient, a measure of solar radiation admitted through a window.

Select a Window Company Known for Expert Installation

The Department of Energy also warns homeowners that “even the most energy-efficient window must be properly installed to ensure energy efficiency and comfort. Have your windows installed by trained professionals according to manufacturer’s instructions; other­wise, your warranty may be void.”

There’s a lot to consider when installing windows. The techniques vary depending on the type of window and the construction material used for the house.
