Now that we’ve covered the basics, let’s proceed with the step-by-step replacement process.
Project step-by-step
What size bathroom fan do I need?
Determining the appropriate size is the first step in replacing your bathroom exhaust fan. Airflow is measured in CFM (cubic feet per minute), indicating how much air the fan can move. To calculate the CFM for your bathroom, measure the length, width, and height of the space and use the following formula:
[ \text{Length} \times \text{width} \times \text{height} \times (0.13) = \text{CFM} ]
Round up the result to the nearest ten to ensure adequate ventilation. Generally, a small bathroom requires a 50 CFM fan, while larger ones need at least 100 CFM.
Remove the bathroom fan cover.
Before starting the replacement process, ensure the power is off and the electricity is not live. Use a screwdriver to remove the old fan cover, exposing the internal components.
Separate the motor from the housing and the duct from the fan
Once the fan cover is removed, locate the screws holding the motor housing in place. Gently remove the screws and separate the motor from the housing, being careful not to damage the wiring. Also, disconnect the duct from the fan, which will be reused with the new fan.
Reuse existing housing system or install new?
Evaluate whether you can reuse the existing housing or if you need to install a new one. It can be reused if the existing housing is the same size as the new fan and in good condition. However, installing new housing may be necessary if there is any damage or the size does not match.
Follow the manufacturer’s instructions for installation details, ensuring a secure and stable mounting for the new fan.
Connect the air exhaust duct to the fan.
Ensure a snug fit by connecting the existing air exhaust duct to the new fan. If the connection is loose, use zip ties to secure it. Proper ductwork is essential for efficient ventilation in your bathroom.
Connect electric wires
When connecting the electrical wires, follow the color coding: white to white, black to black, and green (ground) to green. Use wire connectors or wire nuts for a secure connection. If the new fan comes with easy-to-connect clips, use them for hassle-free installation.
Secure the fan
Once the wiring is complete, secure the fan according to the manufacturer’s instructions. This may involve using brackets or screws to ensure stability. Proper installation prevents the fan from becoming loose or falling out over time.
Test the electric connection.
Before closing up, turn the electricity back on and test the fan to ensure it’s functioning correctly. Listen for any unusual noises or vibrations, as these could indicate a problem with the installation. Address any issues before proceeding to the final step.
Attach the fan cover.
Finally, attach the fan cover securely, ensuring it sits flush with the ceiling and perpendicular to the bathroom wall. A crooked cover needs to be more light, which can affect the fan’s performance. Take your time to ensure a proper fit and alignment.
