Diy Whole House Fan

A DIY whole house fan is a relatively inexpensive and easy way to cool your home in the summer. It works by pulling in cooler outside air through open windows and doors and exhausting it through the attic. To make your own whole house fan, you will need a fan, a duct, a damper box, and a grille.

1. Choose a location for the fan in your attic. It should be centrally located and have at least 3 feet of clearance above it.
2. Cut a hole in the attic ceiling the size of the fan.
3. Install the damper box in the hole and secure it with screws.
4. Attach the fan to the damper box and screw it into place.
5. Connect the duct to the fan and the damper box.
6. Seal any cracks around the fan and the duct with caulk.
7. Install the grille in the hole in the ceiling.
8. Wire the fan to a switch.

Once the fan is installed, you can use it to cool your home by opening some windows and doors and turning on the fan. The fan will pull in cooler outside air and exhaust it through the attic, which will help to lower the temperature inside your home.

Here are some tips for making a DIY whole house fan:

• Choose a fan that is large enough to cool your home. The size of the fan will depend on the square footage of your home.
• Make sure the duct is large enough to accommodate the airflow from the fan. A good rule of thumb is to use a duct that is at least 12 inches in diameter.
• Seal any cracks around the fan and the duct to prevent air leaks.
• Use a switch that is rated for the amperage of the fan.
• Open some windows and doors when using the fan to allow fresh air to enter your home.

Be sure to follow all safety precautions when installing and using a DIY whole house fan.
