How to Install an Air Vent Fan? A Complete Guide



A well-performing air vent fan can add much comfort to your home. From removing harmful pollutants to eliminating unpleasant odors, an air vent comes in. Many homeowners avoid using the air vent because installing it is challenging, but things are not that difficult. 


You can perform the air vent fan installation task following a professional guide. Yes, you need tools and a precise idea of your home's structure. Malfunctioning air vent systems can cause major problems, so proper installation is crucial. 


What Is an Air Vent Fan?

An air vent or solar attic fan is a key component of the home's air venting system. The fan allows the venting system to remove air, moisture, and bad odors from the rooms. It is mounted in the frame and attached to the attic as part of the ventilation system.  


When the fan spins, it draws air inside the home and helps it pass through the exhaust duct. Moreover, the fan plays a prominent role in improving the air quality of your home by controlling the humidity level. 


Depending on your preferred location, you can install the vent fan in your kitchen, bathroom, living room, or laundry room. The installation process will remain almost the same. 


How to Install an Air Vent Fan? 


You need to go through a few steps to complete the task carefully. Plus, as mentioned above, you should have access to some necessary tools like; 



  • A Vent fan.

  • A power drill. 

  • Framing square.

  • Pencil. 

  • Jigsaw.

  • Drywall screws. 

  • 4-inch hole saw.

  • Duck tape.

  • Screwdriver

  • 90-degree duct elbow.

  • Goggles. 


Once you access these tools, the quiet air vent installation process will be super easy. Here’s the step-by-step guide you should follow.


Step 1: Choose the Right Fan


You should not install a random fan in your home air ventilation system. Instead, you should choose the fan based on the room size where you tend to install it. CFM (Cubic Feet per Minute) comes in when choosing a fan. Remember, a larger room requires a higher CFM exhaust fan. Also, ensure the fan's noise level remains low and is energy efficient. The Attic Depot is the best place to purchase attic fans. 


Step 2: Locate or Mark the Installation Point


You must have a clear view of where to install the vent fan. All you need to do is drill a reference hole in that area. Once you do this, you have to climb up into the attic to visualize whether there are any obstacles. It is always recommended to place the fan mounting in between the joints. Choose the center area of the room for a better ventilation process. 


Step 3: Measure the Vent Fan Mounting and Mark It on the Ceiling


Now, based on the size of the fan mounting, you need to make the area. You can use the framing square and mark the ceiling with a pencil. This will give you a proper understanding of how much area you need to cut to install the ceiling air vent fan. 


Step 4: Cut the Marked Area


Once you have outlined, it’s time to cut the marked area. You need to use a jigsaw to perform this task. While cutting the intake port hole, ensure you don’t cut outside the outline. If you do so, placing the fan mounting in the hole will be difficult. Wear goggles to avoid the ceiling dust from touching your eyes.

Step 5: Place the Vent Fan


This is one of the most essential steps in installing an air vent fan. You need to place the fan in the area you cut. Moreover, you need to follow the area of the cutout while installing the fan. But make sure to attach a 90-degree duct elbow to the fan to connect it to the exhaust duct. Next, insert the duct exhaust. 


You have two options: Place the ceiling air vent fan inside your home or do the job from the attic or roof. Once you place the fan, attach a cable connector. Then, insert the slide metal brackets into the fan tabs.

Step 6: Insert the Fan to the Joints


Here you need to use the drywall screws and a screwdriver to attach the fan to the joints. Take 1 1⁄2-inch drywall screws and insert them with the joints using the screwdriver. Make sure you do the same for each mounting bracket of the vent fan. 


Step 7: Route the Fan Through an Exit Point


The exit point can be on your roof or the sidewall. But make sure the distance between the exit point and the fan doesn’t exceed 6 feet. You need to cut the duck hole with the help of a 4-inch hole saw. However, the experts suggest drawing a circle and cutting the hole for better output. 


Step 8: Insert the Exhaust Hole into the Vent Cap


For sidewall exit points, you need to secure the vent cap to the outside wall. Once you do this, stretch the flexible exhaust duct to the wall. Then, install the vent cap using roofing cement and nails for roof exit points. 

Step 9: Connect the Wires


First, cut the power supply by flipping the circuit breaker. Snake the electrical cord through the fan’s designated opening with the electricity safely off. It’s time for some electrical matchmaking: connect the black, white, and ground wires using wire nuts. You also have to ensure a snug fit for each pair. Remember, these connections are the heart of your vent fan’s operation, so treat them carefully.


Step 10: Install the Grille


Secure it firmly in place using the screws you set aside earlier. Now, it’s time to dress up your fan. Hold the plastic grille close to the ceiling and carefully slide its mounting wires into their designated slots. Next, lock it into place. Ready to feel the breeze? Flip the switch and enjoy your new fan!


Step 11: Test the Fan


Once you have performed the above steps correctly, switch the circuit breaker to see whether the quiet air vent fan is working. You’ll surely feel your room vented.
