Exhausting extra co2

Probably a stupid question I’m about to ask, but are constant high co2 levels a problem? I got a meter and checked mine when I was considering a sealed room, but my ambient levels are between 1000-1500 so obviously I decided against it. Is there any reason I’d need to vent it out of the house during lights off or is just worrying about it the best bet? Plants don’t seem to mind but if I can make them do even better than they are I’m all for it(within reason lol).
