Brand new AC unit makes whooshing sound and air "chokes"
I would verify the screw that connects the blower to the blower motor is tight, I have seen where a loose fan (squirrel cage) slipping has caused this exact issue. I don’t have time to look it up right now but there is usually a maintenance over ride some times the plastic cutout that looks like a horizontal I on the right lower side. This may allow you to view the problem and I am not sure but may allow for the filter to be removed and will still turn the blower on.
