- return is designed with the roof space that should act as a vacuum

That makes me think you have a problem with the intake, maybe it's blocked or a dirty filter? Hang tight an expert should be along shortly. Good luck

You have a cold water air conditioner in your house or is this a commercial building ? Cooling tower? Air flow may increase when front cover is removed, but only slightly. Please describe your system.
