If you are looking for ahow-to install a diffusertutorial guide, you are in the right place. When you perform a diffuser installation in your existing HVAC system, you need a few tools and parts. You need anair diffuserwith dampers to control the flow of air.
What You Need for the Project
You need amarkerto trace the diffuser into the HVAC ducting so that you know where to cut into the line. Then you needsnipsor some other type of cutting tool to create the opening in the duct. Check out the video and the steps below on how to take care to protect yourself from sharp pieces of duct.
As you will see, Phil uses a cutting bit in order to create the first hole and then does the rest with the snips. Apower drillwill make the project go more quickly, but you can use a manual screwdriver to secure the damper blade to the diffuser housing.
Diffuser Installation Steps
The video covers all of this (except the one missing step #4), but this gives you a quick reference overview of the basic steps involved in the process:
Place the diffuser where you want to install it into the existingductwork, then trace it.
Use a cutting bit to create a hole in the ductwork.
Use snips to cut out the traced dimensions (be careful not to cut yourself).
The video doesn't show this step, but you want to use the four pre-drilled holes in those holes in the diffuser housing and some Malco Zip-In Screws (probably the HW8X3/4) to attach the housing to the ductwork. No need for tape or glue.
Install the blade into the diffuser housing.
The most important tip that I can offer you is tobe very careful when you cut into theducting. It's very common to nick a finger on one of those sharp edges, and this kind of injury will bleed a lot. Also, you can end up with a lot worse than a bloody finger, so take extra precaution by wearing gloves (unlike Phil) and taking your time on the project.
Knowing how to install a diffuser housing and blades will allow you to create the ideal installation in your home, whether you are making an addition or finishing a basement or attic. Check out thisShoemaker USR52-SC 16" X 8" diffuseror browse the other fun resources here.
