A/C refrigerant lines

Can somebody give me some insight on gurgling refrigerant lines on new construction Goodman heat pump?
Thanks for any advice. BC

That is common on Goodman units.
The sound is from the restrictor piston at the evaporator coil.

This can be an indication of a low refrigerant charge.
If all else functions, I would let it go.

Grab the suction line. If it is cool-cold to the touch, there is likely sufficient refrigerant charge.
