Caulk and seal all openings into your home, especially around doors and windows.
Install window shades or curtains, and close them during the day to keep sunlight from heating your home. Patio covers are also a great means to help shade your home.
Strategically plant trees and shrubs to help shade from the sunlight.
Install a programmable thermostat (and program it properly). Suggested temperature setting is 78 degrees during the summer. (A NEST smart thermostat is a worthwhile invest for your home.)
Change out all lightbulbs to LED bulbs. They do not put off heat and use a fraction of the electricity.
Add more or update your insulation. Newer insulation can be a worthwhile investment for your home.
Have your AC unit serviced to insure it is running properly. Don't forget to change the filters regularly!
Make sure all ductwork is sealed properly and not leaking cool air into your attic or crawl space.
Turn down your water temperature to the "WARM" setting, which is 120 degrees.
Shorten your showers. By simply reducing the lingering time by a few minutes can save hundreds of gallon of hot water per month for a family of four. Showers account for 2/3 of your water heating costs.
Install low flow shower heads and aerators.
These can drastically cut the cost of heating hot water.
Cook your meals in the microwave or outside
on the grill instead of heating up the oven in the kitchen.
Use appliances efficiently.
Do only full loads when using your dishwasher and washer.
Use cold water. Be sure and clean your clothes dryer’s lint trap after each use.
Turn off the lights
in unoccupied rooms. Unplug that spare refrigerator in the garage if you don’t really need it. Turn off TV’s if no one is watching them.
Unplug electronics that continue to use electricity even when they are switched “off”.
Reduce the operating time of your pool filter and automatic cleaning sweep to our to five hours a day and use only during off-peak times.
