I live in a 4 level split. I can oly find one cold air return register and it is on the main or 3rd level. My house is always cold in the upstairs 4th level. Would the lack of more cold air returns cause this?

Hi there, this is a new home and this is in the ceiling of my basement. Is it ok to have plumbing go through joists that are blocked for cold air return? The builder roughed in the kitchen sink and dishwasher incorrectly and my guess is the hvac guy used the two floor joists for cold air return because there was nothing there. They've fixed the location of the plumbing and now the drains and supply come down into the cold air return, the drain exits via a hole in the joist and the supply exits via a rough hole cut into the corrugated plastic that caps the end of the run. Thanks for your help.
