Each summer presents the same dilemma: You need to keep cool, but your air conditioning costs keep climbing along with the temperature. Keep those costs down with these easy-to-follow tips.
Seal in the Cool Air
You’d never leave a window open if you were trying to keep your house warm in the winter; treat your home in the summer the same way by preserving cool air inside. Keep all the windows and doors shut, and fix any leaks around the frames. Check for gaps under your eaves and around cables, pipes, and outflows that pass from the interior to the exterior of your home. The sun beating down on your roof can heat the whole house, so make sure your attic has enough insulation.
Optimize Your Thermostat Usage
If you haven’t already, investing in a thermostat with a timer is a great idea. After all, your thermostat should turn on the AC only when there’s someone home to benefit from the cold air. Make sure there are no appliances or heat sources near your thermostat.
Harness the Power of Sunshades
Unshaded windows can turn your living space into a greenhouse in the summer. Block the sun shining through your windows by installing awnings or shutters on the exterior of your building. Inside, blackout curtains, blinds, and window films help keep the heat from building up.
Reduce Internal Heat Sources
Some household appliances generate a lot of heat. Your oven and stovetop produce the most, but your washer and dryer also put out a good amount of heat. Try to cook and bake in the cool evenings and early mornings; avoid making dishes that require having the oven on for long periods. Try to do laundry during cooler hours of the day and dry your clothes outdoors if you have the space. If possible, move your washer and dryer away from the rest of the house, such as into the basement.
Maintain Your AC System
Replace disposable air filters regularly, and make sure that grills and registers are open all the way and free of any obstructions. Any duct work must be kept in good repair. Ensure that the AC unit has sufficient airflow. At least once a year, have your AC unit checked by a trained professional.
Evaluate the Need for AC Replacement
If your unit is too small or too large for the space you’re cooling or is more than 10 years old, replacing it may be the most cost-effective option. The newest models use much less energy than AC units even a few years old. Switching to an Energy Star–certified unit could save even more power. Depending on your region, you may find that there are financial incentives to replace your unit with a more energy-efficient and environmentally friendly model.
With a few simple tweaks, you can make your home more comfortable without breaking the bank. Use these tips to enjoy your summer while minimizing your AC bills.
