How to Redirect Airflow From Vent


Redirecting airflow is a method of changing the direction that air flows in your case while still using your front intake fans. This will allow you to improve cooling and also create a more uniform pressure throughout the case. Today I will discuss how to redirect airflow from vent to improve air circulation. So let us get into the topic.

Step-wise Guide on How to Redirect Airflow From Vent

Step 1:

Take out the filters. Most of the systems have used mesh filters for filtering the air. They should be removed and taken to a professional place where they can wash them. If you are doing this job at home, open up all your windows so that there will be space between the ducts and make sure that vent is placed properly on top of them. Moreover, clean the grilles that are also installed outside.

Step 2:

Clean the vents properly to ensure good airflow. Use a sharp object with pointed ends to check for blockages in the vents. Remove any blockages you find and dispose of them properly.

Step 3:

Connect the exhaust properly to an outside air vent. This can be done by taking the air fitting tool with you and connecting it properly to the vent outside your house. Now, open up the exhaust fan so that there is suction between the two vents. Make sure that you have not yet flipped a switch for running any other fans inside your home because that may interfere with this test.

Step 4:

See if there is any leakage with the switch on. Once you have opened up the fan, you can check for any air leaks. If there is a leak, air would get into your home through it, rather than outside. Exhaust fans work like a vacuum and suck out all the air inside your home. If this kind of leakage happens, then just make sure to install new grilles to eliminate such problems.

Step 5:

You’re all set! This is an action you take when you’re finished with the installation. Now, just flip the switch that controls the other fans installed inside your house and watch them work properly after testing everything else.

Precautions While Redirecting Airflow From Vent

The following safety measures must be taken when redirecting airflow from the vent: these measures will protect you from injury inside the air ducts and at the ends of air vents.

Wear Safety Goggles:

You should wear safe working goggles before starting this task to prevent dust particles from entering your eyes.

Ensure That There Is No Electricity Flowing Through Those Wires:

If you are not sure about where the electric current is passing through your walls or ceilings, you should disconnect them completely. If it is safe to work with the wires, you should wear rubber gloves and use tape or clamps to seal all outlets after removing them. If you are not sure about anything about electrical wiring, you should always call a licensed electrician.

 Give Vent a Good Wipe Off:

Vent can be cleaned using a dry rag or a vacuum cleaner. Ensure that there is no dust or debris left inside the vent system before proceeding further.

Wear Proper Clothing:

Always wear proper clothes while performing this job inside air ducts and vents. This will prevent you from getting hurt due to falling debris inside the air ducts during the ventilation redirecting process.  

Don’t Make Any Structural Changes in the Vents:

You should never change or alter the structure of the ducts while doing this type of work. For example, you should never install smoke detectors on top of supply shafts. Instead, just look at what is already there and see if it can be done more easily.

Make Sure to Check for Vent Obstructions and Ensure Proper Flow Before Redirecting Airflow:

Before executing the job of redirecting airflow from the vent, make sure that all obstructions are obliterated from the ventilation system and clean them up completely using a vacuum cleaner or dry rag. After completely removing all kinds of obstruction from the ventilation system, proceed further towards the redirection process.


It’s really not that complicated as it sounds like, but it surely takes some time, and a lot of patience is needed for doing this job at home. I hope you have obtained a clear idea of how to redirect airflow from vent, ensure proper precautions during the process. Thank you, and have a good day!
