1 Seal Air Leaks to Keep Cool Air In
As temperatures climb, small gaps around doors, windows, and vents let cool air escape, making your AC work harder. Apply caulk or weatherstripping to seal leaks and keep your home comfortable without wasting energy.

2 Add or Upgrade Insulation
Good insulation doesn’t just help in winter—it also keeps your home cooler in summer by reducing heat transfer. Check your attic and walls, and if necessary, add insulation to maintain consistent indoor temperatures.

3 Switch to LED Lighting
Longer daylight hours mean less indoor lighting use, but when you do turn on the lights, make sure they’re energy-efficient. LED bulbs use up to 90% less energy than traditional bulbs and emit less heat, helping to keep rooms cooler.

4 Install a Programmable or Smart Thermostat
A smart or programmable thermostat helps optimize cooling, adjusting temperatures when you’re asleep or away to reduce energy use. Join the Four County EMC Connect My Thermostat program to earn rewards and reduce energy consumption during expensive demand response events.

5 Use Smart Power Strips
Electronics and appliances continue to draw power even when turned off, leading to unnecessary energy waste. Smart power strips help by cutting off power to idle devices, saving you money on your energy bill.

6 Improve Water Heater Efficiency
Lower your water heater temperature to 120°F to prevent overheating and reduce energy costs. Consider installing an insulating blanket to minimize heat loss, and if you’re planning a summer vacation, set your water heater to its lowest setting before you leave.

7 Keep Heat Out with Window Film or Curtains
Sunlight streaming through windows can quickly heat up your home. Reflective window film blocks UV rays, and thermal curtains help trap cool air inside. Both options reduce strain on your air conditioner.

8 Get Your AC Ready for Summer
Before the heat peaks, check your air conditioning system. Replace or clean air filters, clear debris around outdoor units, and schedule a professional inspection to ensure your system is running efficiently.

9 Adjust Ceiling Fans for Summer Mode
Set your ceiling fans to spin counterclockwise to create a cooling breeze. This helps circulate air more efficiently, allowing you to keep your thermostat a few degrees higher without sacrificing comfort.

10 Reduce Heat in the Kitchen
Ovens and stovetops can add unnecessary heat to your home. Whenever possible, use an outdoor grill, microwave, or slow cooker instead. Run full loads in the dishwasher and use the heat-dry setting sparingly to prevent extra heat buildup. By taking these DIY steps now, you’ll enjoy a more energy-efficient home all summer long. Small changes can lead to big savings while keeping you and your family cool.
