In winter, open shades to let the sunlight to help warm rooms.
In winter, keep your thermostat cooler at night or when the house is empty.
Install a programmable thermostat to heat and cool rooms only when necessary.
Plant trees around your house to cut cooling costs in summer.
Insulate your walls and ceilings.
Install a light-colored or reflective roof.
