I just bought my first home and have a ton of questions. The first being how do I know if I need a dehumidifier? The previous owner had one in the basement. The basement is dry but does have a drain in the floor which goes to the city system. Some days, the air in the basement is a little damp. The basement is 3/4 finished (of course with nasty 1950's panelling).
If I do use one, do I need to use it year round? Also, what size would I need, basement is about 700-750 Sq. Feet.
