Replace a low-hanging duct
Photo 1: Disassemble a duct joint
Unbend the folded portion of each joint’s “drive coupler.” Pull each one off with pliers. Support the duct with two spring clamps and chain and then remove the duct hangers.
Photo 2: Install the new duct
Hoist the new duct into place and hold it with the spring clamps and chain. Line up the joints and insert the top and bottom edges into the S-slips. Install the drive couplers and bend the ends with a hammer. Then install the duct hangers.
Don’t let low-hanging ductwork scuttle your plans for a basement remodel. If the ductwork is in the way, you have three options. You can reroute it or split it into more but smaller ducts. But the least disruptive and easiest way is to replace the low ducts with new ducts that are flatter but wider. In most cases, you can gain several inches of headroom.
Measure the existing ducts that are too low. Sketch out the current duct layout and note the location of each joint. Take the sketch to a professional heating contractor and get a quote for building new, flatter ducts. If the new ducts provide enough headroom, just deliver the old ducts to the contractor to use as a template for the new ones.
To disassemble a duct joint, remove the drive “couplers” (Photo 1). Then install the new duct (Photo 2). Seal all the joints with aluminum duct tape or duct-sealing caulk.
