We hope this helps you with your ductwork repairs in Greenville SC.
In this post we are going to take about ductwork.
Step 1: Remove the Ductwork
Remove existing ductwork where needed. Run the new flexible air duct under the house from the floor return to the underside of the air handler and attach to the metal vent box, or plenum (Image 1).
Note: If the air duct isn’t long enough, it is possible to add extra length. Attach a second air duct to the first by peeling back the insulation and tucking it into the first section approximately 6″-10″ and seal with duct tape. Fold the insulation back in place and roll on the outer layer (Image 2).
Step 2: Secure and Seal Duct
Use plastic ties, placed every few feet, to attach the entire length of the duct to the bottom of the floor joists; this keeps the duct up and away from the ground.
Seal the new flex duct to the new box with plastic ties, keeping the connection between the duct and the box as tight as possible. Once everything is in place, clip the end of the ties, seal everything tight with aluminum tape and burnish with a plastic rib.
Step 3: Create a Wooden Frame
To hold the new vent in place, it may be necessary to create a wooden frame or housing. Measure the opening and cut the 2x4s to size. Nail the frame into the opening and put the new vent in place (Image 1). Center, using 2″ x 4″ braces, and screw in place (Image 2).
