Can you add ductwork to an old house?

To answer the question of whether or not you can replace or install your own ductwork, I’d say it is possible but that I highly recommend enlisting the help of a heating, cooling, and ductwork expert. Ductwork runs all throughout your house, which makes doing DIY repairs yourself a heavy contracting lift.
When should you replace ductwork?

How to install ductwork?
1) Begin installing ductwork at the supply unit using sheet metal ductwork. 2) Run ductwork between floor joists whenever possible, and anchor it in place with galvanized hanging straps. 3) Attach ductwork that branches off and approaches each vent or register in the house. 4) Install the return ductwork by starting at the main unit and working outward in the same fashion. 5) Test the installed ductwork by turning your thermostat all the way up. Listen for any high pitched whistles, which indicate escaping air.
