Foil tape for leaks/seams and depending on the situation, sometimes insulating the ducts is in order.

Stopping any warm air leaks is a VERY good idea!

Insulating ductwork that goes through unheated areas is usually a good idea as well, but stop the air leaks first!

Avoid fabric duct tape.

Foil works well.

It's not necessary to insulate ducts which run through heated spaces.

Foil tape is a patch job. If you want it done right, use a mastic sealant then insulate.

I have never seen mastic at any big box store and trade suppliers don't sell to the general public.

In my area, all plumbing supply houses sell to the public & most carry mastic.

Even the big orange nearest to me has mastic and that store almost never has what I want.
