Cold air return vents can a room still heat up without them?
In order to maintain good air quality you need return air ducts for the furnace. The return air intakes also help balance the temperature differential in the room, return air also helps maintain a safe temperature for the heat-exchangers with out the return air helping reduce the temperature around the heat-exchangers thermal overloads would trip out and shut down the furnace and the danger of rupturing the heat exchanger which would allow combustion exhaust and carbon monoxide entering in to and mixing with the supply air making a deadly situation for the occupant's.
