Fans are a home addition that can enhance any room with the style and size of the fan, as well as the obvious added comfort of the circulation of the air created from it. Installing a fan will give you a sense of accomplishment, and the best part is it can be done in just a couple hours.

  1. 1

    Turn off the power. Go to your electrical box and turn the circuit off for the area you are working in.

  2. 2

    Remove the previous fan or light fixture if there is one. Use the wire nuts to cover the ends of the wires until you are ready for the new fan.

  3. 3

    Make sure the support for the fan is sturdy. If there is none, install the new mounting bracket in the fan package.

  4. 4

    Match up the wires according to colour. The fan will have 3 or 4 wires depending if there is a light or not. If there is a light, there will be a wire for it that is black with a white stripe, red or blue. The fan lead wire will be black, the neutral will be green or copper, and the neutral lead will be white.

  5. 5

    Take the wires from the existing wires in the home and connect them with the wires from the fan. The two white are paired, the two neutral are paired, and the two black are paired. If there is the fourth wire, this one is paired with the black lead. Wrap the wire ends together and secure with a screw nut. If your home wiring does not have a neutral, then the ground neutral wire can be attached to the fan's right clip or screw.

  6. 6

    Finish installing the fan with the mounting screws. Attach the blades to the fan with the screwdriver.

  7. 7

    Connect the source wiring from the home to the light switch. The black and colour wire will be combined and wrapped around the screw at the bottom of the switch. The white wire will wrap around the screw at the top of the switch. The neutral wraps around the neutral screw which is a green colour.

  8. 8

    Install the light switch into a plastic electrical mount box. The box should be installed against a frame board in the home. Screw the switch into place against the wall into the electrical box until secure.

Tips and warnings

  • If additional wiring is needed from your main home source, check with an electrician to make sure the circuit is not overflowed.
