That's a material lift, nothing special for HVAC. We called the beam lifts, because we used them to lift beams.

The lift made it possible for three of us to get that beam up there without having to hurt ourselves...

The companies making lifts have 'end of arm' fittings for all kinds of work. One extends width for drywall, another for narrow pieces, etc.
One has a shelf [cut down pallet] and works as freight elevator to my mezzanine. Sure, trips up and down stairways but far less than hand carry.
