Make sure your refrigerator door seals are airtight. Test them by closing the door over a piece of paper or a dollar bill so it is half in and half out of the refrigerator. If you can pull the paper or bill out easily, the latch may need adjustment or the seal may need replacing.
Install white window shades, drapes, or blinds to reflect heat away from the house.
Don't keep your refrigerator or freezer too cold. Recommended temperatures are 37° to 40°F for the fresh food compartment of the refrigerator and 5°F for the freezer section. If you have a separate freezer for long-term storage, it should be kept at 0°F.
To keep your retracting tape measure working smoothly wipe the metal blade with a small dab of car wax, then wipe with a clean cloth. This will help protect the blade's finish and keep it retracting smoothly.
