Extra INFO: Be sure and check your local codes for pipe sizes and balancers if needed in the main box. This helps guide the airflow to rooms at a farther distance too. Check ratings for pipe sizes too. Use a larger “Y” if needed in longer runs. Use foil duct if your in a colder or hotter climate. Unfortunately, our local hardware stores only carried black “trash bag” covered ducts. Ask your city inspectors of a list of codes. Some states do not allow unlicensed homeowners to run their own duct work. Check your cold air ducts as well. Air must flow correctly. Study the subject well before going off anyones Youtube video. This is just how we did the runs. Good luck!
