Insulation: Have the correct amount of insulation in your walls and attic. If you are not sure about your insulation, call your local insulating company or contractor to have it checked.
Your attic must be property vented to keep the home cool.
Insulating your wall outlets and switches will help reduce cold air from coming into the home. Check that pipes and wires coming into the house are caulked. (This will help keep the critters out too)
Windows: Double-pane is the norm. (Two pieces of glass with a sealed in air space) If you have single pane windows, install storm windows to reduce heat transfer. Caulking and weather stripping will reduce air leaks. In summer, draw blinds, shades, or drapes to keep the heat out. In winter, close them at night to keep the heat in.
Doors: Be sure all doors fit properly, and have weather stripping and caulking.
Have the humidity in your home at around 40. This will make your home feel warmer, therefore, you can lower the temperature in winter.
Heating/cooling ducts: all joints in ducts should be sealed to avoid air leakage.
If you have a fireplace, be sure the damper is closed when not in use. Keeping the fireplace doors closed will also help reduce heat loss.
Air conditioners: be sure the unit is free from plants, shrubs, and dirt. Locate the unit on the north side of the house or in a shady spot. Clean the filter regularly. Be sure your air conditioner is the correct size for your home.
Install a programmable thermostat. You can save as much as 10% a year if you turn your thermostat back 10 – 15% for 8 hours. Keep the temperature down as low as comfortable in the winter and as high as comfortable in summer.
Be sure furniture, curtains, etc. are not blocking heating/cooling vents.
Hot water tank: insulate the tank and the outgoing hot water line. Don’t buy a water heater that is too big or too small for your home. Drain a bucket of water from the bottom of the tank yearly to eliminate sediment that may have built up.
Leaking faucets can waste gallons of water per month.
Don’t let the water run when doing dishes, shaving, brushing your teeth, etc.
Have lights where you need them most: at your desk or work area, rather than a general ceiling light.
Fluorescent bulbs use 75% less electricity. Halogen bulbs are also efficient.
Did you know that many electronics in your home use power even when not on? Unplug battery chargers, game consoles, TV’s, etc.
Lighter wall colors will reflect more light while darker wall paint will require more lighting.
