When the Texas heat bears down, there’s one appliance that rides to the rescue: your air conditioner. Since cooling in the summer accounts for a major portion of residential energy use, we’d like to share with you some ways you can reduce air conditioning’s effect on your power bill.
Change or clean the air filter regularly.
This is probably the most important step you can take to increase efficiency and reduce the wear and tear on your central AC system. Your system will have to work harder to force air through a clogged filter. This advice also applies to those who rely on window AC units. Ensure that those units are also properly weatherstripped to prevent air leakage around the unit.
Use a programmable thermostat.
These devices will turn your temperature up automatically during times of the day you specify, such as when nobody’s home. In fact, if properly set, it can take a significant chunk out of your cooling bill. If you purchase one, it’s important to actually properly program it—a step many people skip.
Luckily, programmable thermostats have become easier to use in the past few years. Newer ones can learn your usage patterns and automatically adjust temperatures without needing your intervention. Some can even be adjusted remotely with a smartphone.
Use fans wisely.
An easy way to feel comfortable while setting the temperature up a couple of degrees is to use a fan. The air moving against your skin evaporates moisture, which makes you feel cooler. Be sure to turn fans off when nobody is around. They’re only effective when blowing directly on someone.
Draw blinds or shades during the day.
Keeping the sun's heat out of a room will help it stay cooler. Open shades after sunset to allow heat to escape.
