Wall fan installation

An experienced professional installer is the best person for the job. When not properly vented to the outdoors, exhaust fans send the moisture and fumes to another area of the home, which causes mold growth and lowers air quality. And failing to seal the vent pipe correctly can lead to water damage to your roof or wall. Or, you may need a larger or more powerful exhaust fan replacement and end up buying the wrong unit to install.

A licensed electrician from Mr. Electric can guide you to the right product for your needs and perform your exhaust fan installation right, the first time. If your current fans are too small, underpowered, or improperly vented, we can install the right exhaust fan to solve your home ventilation problems. When Mr. Electric adds or replaces an exhaust fan, you may want to take the opportunity to upgrade to a multi-functional fan. The saw will start doing its job.

All you need to do is to guide the cutter flawlessly towards the marked line. After the first round of cutting, just use the hammer and pliers to take out the brick or wood from the hole. Before inserting the fan into the hole make sure that you have properly cleaned the inside part of the hole so that you can easily see the attic through the hole. You can use a powerful vacuum cleaner or just use a mop for this cleaning job.

Now, go to the attic and connect a 4-inch wide and degree duct elbow with vent fan carrier or fan housing. You will find a port there to connect it. After connecting it, you should secure the connecting with duct tape foil. To do that, get the fan out of its box and unfasten its wiring. Before fixing it into the hole, connect the fan with a power outlet and check if the fan is working properly or not.

Now, place the fan on the fan housing and set it exactly in the middle of the carrier. Take out the fan of the hole and connect the cable connection securely. After that insert the fan again and attach the given screw to secure the fan on that position firmly. Staying inside the attic, choose a position in the middle part of the sidewall. Mark that position and make a small see-through hole on that spot.

Make sure that the hole is not too far from the fan. Use a ladder for secure climbing. Take the reciprocating saw and make a diamond-shaped hole in that position. This kind of hole is perfect for attaching round or square shape objects on the wall using screws. Finally, add the connector duct with the wall cap. And, attach the connector with the flexible duct and secure the ducting hose firmly with duct tape. Take the duct line inside by pushing the cap inward with your hands.

Once the cap reaches close to the wall, attach it firmly to that position using screws. This step is a very significant part of the bath fan installation process. You may directly connect the fan with the bathroom light. As a result, you can turn on and off both of them by switching the same switch. Make sure that you have securely connected all the wires and fastened all the screws.

If you are not feeling enough confident to do this step by yourself then do not take risks. Seek help from an expert in this regard.

Remember there are several brands and sizes of exhaust fans out there, so you need to choose the appropriate one for you. But whatever you have in front, these are the basic steps to follow. You may also love to read my another post on how to vent a bathroom fan through the roof.
