As summer temperatures climb, homeowners are seeking effective ways to keep their homes cool without facing high electricity bills. Energy experts offer several strategies for efficient cooling and cost savings.
The U.S. Department of Energy reports that homeowners can save as much as 10% annually on cooling and heating by adjusting their thermostat by 7 to 10 degrees for eight hours a day. To maximize savings during summer, it is best to keep the difference between indoor and outdoor temperatures as small as is comfortably possible.
Utility provider DTE Energy recommends a specific setting of 78 degrees. For every degree you raise your thermostat, you can save between 1% and 3% on cooling costs. Raising the temperature a few degrees higher when you are away from home can increase these savings further.
In addition to thermostat management, several household habits can help reduce indoor heat:
- Adjust Cooking Methods: Use a microwave, slow cooker, or outdoor grill instead of an oven, which generates significant indoor heat. When using the stovetop, turn on the exhaust fan to vent hot air outside.
- Block Sunlight: Close blinds and curtains on sun-facing windows to prevent solar heat from warming your home.
- Time Appliance Use: Postpone running heat-producing appliances, such as clothes dryers and dishwashers, until the cooler evening hours.
- Reduce Humidity: Use the air-dry setting on your dishwasher and take shorter, cooler showers to minimize heat and humidity, which can force your air conditioner to work harder.
Proper air conditioner maintenance is also crucial for efficiency. Key tasks include:
- Check the Filter: Clean or replace your air conditioner’s filter every month.
- Clear the Outdoor Unit: Keep the area around the outdoor condenser coil free of leaves, shrubs, and other debris, maintaining at least 18 inches of clearance for proper airflow.
- Inspect the Drain: Ensure the unit’s outdoor drain remains clear and unclogged.
