How to Secure Heat & Air Ducts to a Subfloor
Heat and air ducts run from the furnace to different rooms of the house. These ducts help heat and cool the house depending on the time of year. If you are making an addition to your house, or just looking to add more air ducts to your home, you can run them through the subfloor at various locations. This will help get better air circulation and keep your house at the temperature you want it. Does this Spark an idea?

Inspect the ducts in the basement that you will be running through the subfloor. Follow along the duct and verify they are all secure in place together. Run a tape measure across the length and width of the final duct that will be installed into the subfloor. Record the measurement.

Mark the location from the basement on the subfloor where the duct will be installed. Press the top of the duct up against the subfloor and outline it with a pencil so the proper hole can be cut in the subfloor for the duct to fit through.

Remove the duct from the subfloor and attach a wood blade to a reciprocating saw. The subfloor will likely be made of 3/4-inch plywood that can easily be cut with a reciprocating saw. Press the blade of the saw up to the subfloor along the corner at the pencil mark.

Press the trigger and cut carefully along the pencil line with the saw. Move from side to side until a hole has been cut out. Turn off the saw and wipe away any excess dust from the cut with a clean rag.

Slide the duct into the opening to verify it fits snugly into place. Move upstairs and set a vent down on top of the opening and into the duct underneath. Secure it in place with the two provided screws through the pre-drilled hole on each side of the vent with a Phillips head screwdriver.
