Blasting the air conditioning to counteract stifling heat can provide much-needed relief this summer, but the utility bills that follow might not be as pleasant. The good news is you might have more control over your energy use than you think.
According to the Bureau of Labor Statistics, the price of electricity has been steadily climbing over the past two years.
“Most U.S. households will continue to pay high costs for energy throughout the summer because of high energy prices and the anticipated [high] temperatures,” says Courtney Klosterman, home insights expert at insurer Hippo.
Paula Glover, president of the Alliance to Save Energy, a nonprofit that advocates for energy efficiency policy, estimates that based on numbers from the Energy Department, consumers could save 10% to 20% a year on energy bills just by shifting habits and making some energy-efficient investments.
But, she adds, “You have to be diligent.”
Here are five steps you can follow to lower your energy bill this summer:
TAKE A BASELINE
Before making any changes, it’s helpful to examine how much energy you currently use, says Angie Hicks, co-founder of Angi, a website that provides information on home services. Hiring a professional to give your home an energy audit typically costs between $200 and $700 and gives you helpful information about where your home might be leaking, she adds.
You can find one through local home service provider listings, and some utilities offer the service for free. [For instance, Entergy Arkansas offers free assessments under certain conditions, see arkansasonline.com/710assess.]
Electronics themselves might be leaking, says Ethan O’Donnell, digital editor of FamilyHandyman.com, a website about home improvement projects. Televisions, appliances and all kinds of other electronics can use energy even when they are turned off, he says. A tool called an electricity usage monitor, which can be found for under $15, helps determine exactly how much.
O’Donnell discovered that his lamp, appliances and phone chargers were using more electricity than he realized even when powered off, so he made an effort to unplug them when possible and estimates he saves at least $50 a month from those changes.
EFFICIENT HABITS
Simple changes like adjusting your thermostat, turning lights off when you leave the room and keeping windows and doors shut when the air conditioning is on can go a long way, Glover says. Installing a smart thermostat, which automatically adjusts the temperature based on time, your habits and the season, can also help, she adds.
Hicks suggests leaving window coverings closed during the day to help keep the sun’s heat out of your home and getting a seasonal tuneup to your air-conditioning system to make sure it’s working efficiently. Changing your air filter monthly or quarterly also helps it run better, she adds.
SMALL UPGRADES
Small home improvement projects, such as adding or replacing weather stripping that seals leaks around doors and windows, can reduce your energy consumption significantly, Hicks says. “Walk around your house with a lit candle and if the flame flickers, that’s where drafts are coming in. That’s a good candidate for weather stripping,” she says.
Another simple job involves swapping out incandescent bulbs for LED light bulbs, which use at least 75% less energy, according to the Energy Department. “It seems like nothing but has an enormous impact when we do it collectively,” Glover says.
UPDATE APPLIANCES
While buying new appliances can be expensive, the investment can pay off in energy savings, especially when you select products with the Energy Star certification, a program run by the Environmental Protection Agency.
SMART INVESTMENTS
According to Angi’s State of Home Spending in 2022 survey, 29% of homeowners say they plan to add solar panels to their home within the next five years. Updating the heating, ventilating and air conditioning system, or HVAC, was another popular choice (23%). Those kinds of big investments can pay off over the long run, says Hicks, who adds that federal income tax credits are available.
Installing doors as a barrier to different zones in the house can help improve efficiency by letting you control what gets warm and what stays cool, says Jonathan Flynn, a senior building analyst with Home Energy Consultants in Pleasant Valley, N.Y., and a certified Home Energy Rating System rater. “One of the big flaws in most two-story homes is that there is a stairway that leads up and no door at the top or bottom,” he says.
To prevent that energy leakage, Flynn installed a sliding door at the bottom of the stairs in his own home, but he recognizes that doing so might not be practical or desired by all homeowners with open floor plans. Still, he encourages homeowners to at least consider making these kinds of changes, even if they aren’t currently popular.
After all, he adds: “Energy efficiency work in your home is one of the few investments you can make that will actually pay you back.”
