Never use duct tape, as it is not long-lasting.

What happens if duct size is too small?
Ducts that are undersized will increase the static pressure, which will result in excessive noise as air moves through the system. It is often loud enough to be distracting, so it will not be difficult to overlook and should be addressed, as undersized ducts overwork the heating unit.

What is the most efficient ductwork?
For instance, round duct is the more efficient shape in terms of material use, resistance to airflow, and air leakage. “The tradeoff is that round duct will not always fit in the space provided. In these cases the duct is converted to rectangular or flat-oval so that it can fit the available space.
Should exposed ductwork be insulated?
A: Depending on the climate and the ducts’ location, it may not be necessary to insulate them. … The ducts are exposed to the same cold, heat and humidity that exist on the outside.
