co2 sealed room, only vent lights off? if at all?

[geestacker]

Yes you can vent but I also know of many who use A/C and they don't vent at all. Unless they open the door and enter the room.

Now what I would do but they have no problem and their smoke is always frist rate.

thanks zandor, also will this ac unit be better than the central used throught the house to keep the room totally sealed and temps at 85-90?
