my basement just freed up, and I'll be cutting it in 3rds I was wondering, I'm going from 2 600 and a 400, to 4 600 and a 400. how much more do you think it wil cost, I don't want to draw attention to my bill, unfortunatly I live in a politically challenged state. say a prayer. anyway, I'm losing a wall unit ac and a 4 gl. dehumidifier.my new area has kick ass exhaust and intake. any suggestions would be apreciated
