Fans

Vents and fans controlled by humidistat in basements and crawl spaces help ensure proper air circulation and control moisture build-up.

Try using synthetic oil in your workbench oil can. It works wonders in rejuvenating old electric motors, fans, etc.

Whole-house fans help cool your home by pulling cool air through the house and exhausting warm air through the attic. They are effective when operated at night and when the outside air is cooler than the inside.

Running a ceiling fan in the summer can make you feel 4 degrees cooler, even without air conditioning. Remember to run your ceiling fan counter-clockwise in the summer and clockwise in the winter.

During winter, a ceiling fan can move heat trapped near the ceiling back into the living area. This is especially valuable in rooms with high or vaulted ceilings. Remember to run your ceiling fan counter-clockwise in the summer and clockwise in the winter.

Energy Star labeled ceiling fans with lighting attached use 40% less energy than conventional models, keeping you cool for less.

In the hot summer months, use an attic fan to draw hot air out of the attic. Use a whole-house fan to draw fresh air in through windows and exhaust it out roof vents.

Places that are often or always damp can be hard to maintain completely free of mold. If there’s some mold in the shower or elsewhere in the bathroom that seems to reappear, increasing the ventilation (running a fan or opening a window) and cleaning more frequently will usually prevent mold from recurring, or at least keep the mold to a minimum.

If your home can’t accommodate central air conditioning, try a whole-house attic fan. This device pushes hot air out through attic vents, lowering the temperature throughout your home about five degrees in less than ten minutes. Attic fans cost less than 25 cents per day to operate.
