How to wire a roof fan.

Whether you are looking to wire a ceiling fan with lights to one power switch or add a fan in a room without a switch source this guide will teach you how to wire a ceiling fan using four common scenarios and the best wiring methods. Roof fans are mounted on plastic or sheetmetal bases that serve as flashing. Connect the black thermostat wire to the black cable wire the white thermostat wire to the white cable wire and the ground wire to the green ground screw in the box. Gable fans fit into the gable vent and can be set to operate only within.

Wiring ceiling fans can seem complicated but the task really just depends on the type of fan you are installing and how you want it to operate. When the fan is securely mounted carry it over to the vent and nail. On average labor costs run between 100 300 and the fan itself may range from as little as 50 to more than 500. To save time use an existing roof or gable vent to install your new attic fan.

Simply cut an opening in the roof typically near the peak and install the fan over the opening. Pricing for attic fan installation varies depending on fan type and its location. You also want a fan that s appropriate for the square footage of your attic space by checking the manufacturer s specifications. This way you don t have to cut a brand new hole but simply make the hole for the vent larger so it can accommodate the fan.

To install an attic fan over a gable vent in your attic trace the body of the fan onto a piece of plywood that s wide enough to mount on the studs on each side of the vent. Use wire nuts to connect the black wire from the 12 2 wire to the black or red wire in the attic fan the white wire to the white wire in the attic fan and the two ground wires. Even if your roof already has ridge vents and plenty of ventilation built in it s a good idea to install gable fans or roof fans to help blow hot humid air out of the attic. Attic ventilation fans also tend to be quite energy efficient in terms of their own operation.
