How to Install a Ceiling Vent Booster Fan

Installing a ceiling vent booster fan in the bathroom, or in any other room in the house, can increase the effectiveness of the fan, allowing all fumes, moisture and dirt particles to be safely deposited outside of the house. This is an easy job and can be completed by any homeowner within a couple of hours. When choosing the booster vent that you want to install check the local city building codes because some models will require the help of an electrician when wiring it into the house. If the room already has a fan, than it is a simply task to wire the new unit in, and an expensive electrician will not be needed.

Tools and Materials Needed:

  • Vent booster fan
  • Electrical wire (if needed)
  • Electrician pliers
  • Wire caps
  • Power saw (if needed)
  • Small ladder or step stool

Step 1 - Remove the Old Vent

Before working on any project that involves electricity, find the circuit that runs the particular area and turn the breaker off inside of the panel. Remove the bolts, or screws, that are holding the current fan in place and remove the wires. Make sure to put the wire caps back on each individual wire to prevent the chance of any problems. Remove the entire fan unit from the ceiling, cutting around the edges if the sheetrock is covering the corners.

Step 2 - Install the Booster Fan

Measure the new booster fan and make sure that the hole in the ceiling is large enough to accommodate it. If it is not, then use a power saw and re-cut the hole so that it is slightly larger than the base of the booster vent. Push the vent into place and screw or bolt it down so that it stays in place. Wire the unit using the existing wires and wire caps. If the room does not have any wiring, then you will have to wire the room, making sure to install the electrical runs and junction boxes correctly in order to prevent the chance of starting a fire, or worse yet, getting shocked when using it.

Step 3 - Finish

Attach the booster vent fan cover into place, as well as any trim that the unit may have come with. Turn the power back on in the fuse panel and turn the vent on, making sure that it is working correctly.

Installing a booster vent in the ceiling of any room is an easy project and can easily be accomplished by any homeowner. As long as the fan is not a new installation, most of the time an electrician will not be needed when wiring it in. Just be aware that electricity can kill, so treat it with respect and always turn off the main power source before beginning the project. Never try to take shortcuts and work with the power on. Turning the light switch to the off position is not an acceptable way to turn the power supply off.
