When the summer heat hits, your air conditioning becomes your best friend and your electric bill’s worst nightmare. While upgrading to a high-efficiency unit or adding insulation can help, there are plenty of completely free ways to cut cooling costs without spending a dime. Here are the top strategies you can start using today.
Sunlight streaming through windows is beautiful, but it also turns your home into a mini greenhouse. Keep blinds, shades, or curtains closed during the hottest parts of the day, especially on south- and west-facing windows. This simple step can lower indoor temperatures by several degrees.
Ceiling fans and portable fans do not actually cool the air, but they move it around to make you feel cooler. Run ceiling fans counterclockwise in summer so the air blows downward. You can also place a box fan in a window at night to pull in cooler outside air.
When outdoor temperatures drop in the evening or early morning, switch off your AC and let the cool air in. Create a cross-breeze by opening windows on opposite sides of your home. Close them again once the day starts heating up.
If you are cooling spaces you are not using, you are wasting energy. Shut doors and vents in unused rooms so your AC can focus on the areas you actually occupy.
Every degree you raise your thermostat can save about 3% on cooling costs. If you normally keep it at 72°F, try 75°F instead. Use fans to maintain comfort at slightly higher temperatures.
Ovens, stovetops, dryers, and even certain electronics release heat that makes your AC work harder. Cook outdoors, use a microwave, or run appliances in the early morning or late evening to keep indoor temperatures lower.
A dirty filter reduces airflow and forces your AC to run longer to achieve the same cooling. While replacement filters cost money, most systems already have a reusable one you can rinse and dry for free.
You do not want cool air escaping through cracks. Walk around your home and feel for warm air leaks near doors, windows, and vents. Even temporary fixes like rolled-up towels can make a difference until you can do permanent sealing.
If you have trees or shrubs, take advantage of them. Keep blinds open on shaded windows for daylight without added heat. This saves on cooling and also reduces the need for artificial lighting.
Cutting your AC bill does not have to cost a cent. By making small adjustments such as closing blinds, using fans, and being strategic with windows and appliances, you can keep your home comfortable and your wallet happy all summer long.
