HVAC guys use offset tin shears, which come with red or green handles.

I need to cut 2 rectangular openings in an existing HVAC supply and return
ducts.

How can I do this?

I've tried using a power jigsaw with a metal cutting blade -- big mess.

I see things like power shears when I do Google searches, but that seems
like a whole lot of money to spend to just cut the 2 openings.

Are there any hand tools or cutting chisels that will work for this?

Any other suggestions?

The HVAC crew that installed my new furnace last week did as others have
described here. Used a hammered cutter to make a simple slit in the sheet
metal, then used offset tin snips (they'll save your hands a lot of cuts) to
make the rectangular opening.

Yes there are hand tools for this.

Why are you doing this?

To provide heat and AC to a basement. The basement currently has supply and
return ducts running across the ceiling, but there are no supply vents or
return vents.

I just did the tin snips routine today and it worked without too much
trouble. I also did what someone else here suggested and folded back a tab
of the sheet metal on each end to create a double thickness and make the
opening more rigid. That worked well too.
