Venting your clothes dryer directly into the garage could be a building-code violation and a bad idea. Dryer vents exhaust a large amount of water vapor. Putting this condensation into your garage could create rust on unpainted surfaces, and worse, mold inside the walls and ceiling. Clothes-dryer venting should be to the outside.
Does your garage heat up like an oven? Once the heat builds up in the objects in the garage, they can radiate heat for hours after the direct sun is gone. Insulation and ventilation fans will help reduce the temperature inside your hot garage.
To keep your attic cool, your attic ventilation requires moving massive amounts of air. More than natural ventilation will do. Attic ventilation fans or turbine roof vents will assist in moving the air. But, powered attic fans can draw your air-conditioned air out of the house.
Consider an attic fan if your attic gets as "hot as blue blazes." There are solar attic fans available. They work great on a sunny day. But the solar powered attic fans do not work on cloudy days or when the sun goes down. However, the attic still has hot air inside at sunset.
Bathroom exhaust fans are vital components of your home's ventilation system. Bathroom fans not only exhaust offensive odors, they also pipe vast amounts of humid air to the exterior of your home. Bathroom vent fans come in all types and sizes, but I prefer the ones that have the fan motor located in the attic. These residential bathroom exhaust fans are the quietest ones I have ever used, and they are extremely powerful.
Air vents replace the air in your home that is used by your hot water heater, furnace and other vents. Tim Carter explains how they work and why they are so important to have in your home. In modern homes, that are very tight, a fresh air vent brings in necessary air. This video shows you how an air vent works in your home.
Ceiling fans can keep you cool and save lots of money. Not all ceiling fans work well. The best ceiling fans have balanced motors and blades. Ceiling fans keep you cool the same way a hurricane forms in the ocean. You can install ceiling fans anywhere you need cooling, even outdoors on a covered porch.
Dryer vents need to be cleaned on a regular basis. The flapper door on exterior dryer-vent housings must be checked for lint buildup. If lint builds up on the flapper to such an extent that it will not close completely when the dryer is off, all sorts of interesting things can crawl inside your vent and dryer.
Whole house fans and attic fans are often confused. Solar attic fans are a new group of products that use solar energy to move hot attic air. Attic exhaust fans remove hot air from attic spaces, while whole house fans remove hot air from both living spaces and the attic at the same time.
Clothes dryer vents can actually create water leaks. If the clothes dryer vent pipe gets cold, the warm, moist air inside condenses and turns to liquid water. This water can leak from the vent pipes if the seams are not taped. The best way to stop clothes dryer vent pipe leaks is to make sure the pipe does not get cold.
