how do u keep a sealed room cool during winter when its below freezing? i have a window ac but i was told its not a good idea to run cause the coil can freeze. i want to keep the room sealed so what should i do?? i really dont want to buy a portable ac unit.. should i just run a passive intake outake with scrubbers, filters and just run co2 during the night??
