5 Tips to Wiring an Exhaust Fan 5 Tips to Wiring an Exhaust Fan

Wiring an exhaust fan is not difficult. In order for the exhaust fan to work properly, care and attention need to be taken during the installation process. If an exhaust fan isn't installed correctly, you run the risk of developing mold and mildew behind the walls. This can be difficult to detect and even harder to correct later. There are a few things that can help you along the way.

Tip 1- Dealing with Power

Before you work with any type of wiring in your home, the breaker should be flipped. While it may be tempting to only cut the breaker for the bathroom, it's actually a good idea to cut the power to the home entirely. This will ensure that there are no live wires that you aren't expecting. In older homes, the wiring isn't always predictable. Cutting the main breaker is really the safest way to go.

Since you will have no electric light once you do this, it's a good idea to try to do this job during the day, when you can open blinds or curtains to allow sunlight in to the room. A flashlight is also a must.

Tip 2- Housing Boxes

An exhaust fan will have a housing box. This is needed for the fan to stay put. It will also allow a way for the ductwork to attach to the fan securely. Don't skimp on the housing. You will be much better off purchasing a higher quality housing box, or building one yourself if you choose.

Tip 3- Follow the Directions

While many people think this is a no brainer, it is worth mentioning. Wiring diagrams can differ from one unit to another. Using the diagram provided by the manufacturer for your exhaust fan will ensure that all the wiring is done correctly and will reduce the risk of malfunction or danger.

Tip 4- Snap On Pieces

Many exhaust fans will have a cover that simply snaps in to place. This is the easiest way to finish everything off. Some models will require you to use screws to attach the cover. While this isn't difficult to do, it can be hard to manipulate as you stand on a ladder and try to use a screwdriver or a drill. If possible, try to choose models with the snap on covers for ease of installation.

Tip 5- Have a Friend to Help

You will need to climb up on a ladder to access the ceiling for the exhaust fan. Even though the installation is simple, standing on the ladder and trying to hold a flashlight, other tools, and look at diagrams can be tricky and dangerous. Having a friend handy will take a lot of the stress off and make for a safer environment. They can read off the diagram, hand you the tools, and hold the light when you need them to.
