Managing your Thermostat
By Lou Carlozo, Tribune Brand Publishing
During hot weather months, it doesn’t take much of a thermostat tweak to send your energy bills soaring. The question is: how can I best manage my cooling costs without sacrificing comfort?
“We will be tempted to crank the air conditioner, but it’s a drain on the power grid, an inefficient use of energy and a huge expense,” says Suzanne Jones, vice president of the Association of Energy Services Professionals. “There are smart ways to stay cool and remain energy efficient.”
You might think your thermostat can handle the task all by itself, but the truth is, it needs a little help to get the job done. So, here are some of the best ways to save energy and beat the heat, based on suggestions from Jones, government sources and Orlando Utilities Commission:
Use smart thermostats
“Using a smart thermostat will save up to one-third of all your heating and cooling costs if used properly,” Jones says. “You can adjust the temperature in your home from your phone or mobile device if you are on vacation, at work or spending the day away. You can also pre-program different temperature settings throughout the day just in case you tend to forget to adjust the thermostat manually when you leave.” Jones adds that while smart thermostats can cost anywhere from $150 to $300, “they more than pay for themselves.”
Use ceiling fans
Jones highly recommends ceiling fans, although many consumers don’t fully understand how they work. The fan cools you down by triggering evaporation from your skin and forcing warm air away from you. The thing to remember is: fans cool people, not rooms, so it’s best to turn them off when you leave. Using a ceiling fan can make you feel anywhere from three to eight degrees cooler. Be sure to factor in the cost of installation, especially if you need an electrician. And shop around for bargains. Sales on fans are plentiful this time of year — some models cost as little as $50.
Easy does it
When you crank your air conditioner, that sudden blast of cold air may feel nice, but it’s wasteful. “It’s a much more efficient use of energy to use air conditioning to maintain a stable temperature throughout the day,” Jones says. “Make it slightly cooler if need be during the day, and warmer at night. But adjust gradually. This saves energy because the house doesn't have to be completely cooled all at once.”
Consider an energy audit
“Talk to your utility,” Jones says. “Utilities are excellent partners in making your home more energy efficient and they will have a number of incentive and rebate programs for you to take advantage of. These include home energy audits, which are often free or very inexpensive and will show you how to save energy in your home.”
Convert to LED bulbs
Many people shy away from using LED bulbs because of they are more expensive. But as Jones puts it, “Converting to LED light bulbs will cut down on the heat generated by incandescent bulbs. For example, an LED bulb may cost you about $20, but it will save you as much as $140 over the 20-year life of the bulb.”
Keep direct sunlight out
Window treatments play a big role in allowing you to set your thermostat at a higher temperature setting and stay cool. “By using blinds, shades and drapes, you will reduce the amount of radiant (solar) heat into your home,” explains David Mayer, a conservation specialist with Orlando Utilities Commission. “This translates into a cooler, more comfortable home and allows you to potentially raise your air conditioner temperature setting.”
Mayer says every degree that you’re able to raise the AC temperature setting will help you save between 6% - 8% on your cooling cost. So a small tweak can add up to big savings on your electric bill.
According to Energy.gov, medium-colored drapes with white-plastic backings can reduce heat gains by 33 percent. With interior blinds that number jumps to 45 percent. And if you’re up for installing an awning, that’s the best solution of all. Window awnings can reduce solar heat gain in the summer by up to 65 percent on south-facing windows and 77 percent on windows that face the setting sun in the west.
“I would agree that a large portion of heat gain through windows can be reduced with window treatments,” Mayer says. To prevent an even larger portion of solar heat from entering your home, he recommends installing window film or solar screens, for which OUC offers a rebate.
“One additional benefit that solar screens offer is the ability to remove them during the winter to naturally heat your home with sunlight,” Mayer says. Another alternative, he notes, is to plant trees on the east and west sides of your home to provide natural shading during the warmer months.
Look for drafty areas in your home
“Seal drafts to ensure that cold air is not escaping,” Jones advises. Here’s why: When cold air escapes, your air conditioner has to work harder and you have to set your thermostat lower to achieve the same cooling effect. Do-it-yourself weather stripping for doors and caulk for windows is cheap and easy to install. Also make sure to caulk around the holes where pipes go into the wall under sinks — a less obvious source of air leaks.
Finally, make sure that your central air conditioning unit bears the Energy Star seal. Government statistics show Energy Star certified units have higher seasonal energy efficiency ratio (SEER) and energy efficiency ratio (EER) ratings, making them more than 15% more efficient than conventional models.
