Yes, during boiling you're vaporizing gallons of liquid and that liquid will condense onto your walls, ceiling, etc unless properly ventilated. We recommend speaking with an HVAC specialist to avoid this. We use a 400CFM exhaust fan for our in house test brewery and that works well to exhaust the vapor out of our brewery.
