Basement Humidity?

I have a raised ranch and the basement is split finished basement with a boiler/tool room. I have a dehumidifier that works well but I was curious as I read mention of air circulation is important. I have Central air in the finished basement part. But would a fan help along with the dehumidifier remove moisture? Would an exhaust fan in the boiler room part help?

Hi xx,
What are your moisture readings?
I'm not sure where you are having problems, the finished area or is the boiler/tool room a separate area with high moisture?

The finished basement is about 25x15. divided by a wall and a door to the tool/boiler room 25x10. both rooms have windows the finished part has ac. The dehumidifier is in the toolroom since I noticed moisture by rusting tools. I am sure the finished basement as well not sure best are to but dehumidifier but I have in toolroom. I was wondering if an exhaust fan or regular fan would help?

The air conditioner should take care of the finished side. Since the outside air probably has more moisture in it than you want, I would just use a dehumidifier on the tool room side and do not ventilate. A good dehumidifier should control the humidity with no extra air circulation and certainly no exhaust to the outside.

I'm for just the dehumidifier as well. Sounds like you don't need one with much capacity, either.

do you mean the windows in the tool room should be closed during summer months?

Humidity is a combination of moisture and temperature. If it is 80 outside at 80% humidity and you invite that air into a somewhat cooler garage. the 80% RH can jump to 100%, especially overnight. Yes there are times when you can leave the windows open, but you need to judge whether you are increasing the moisture in that room or decreasing it.

In the winter the cold outside air becomes very dry as it warms up. But in the summer it goes the other way. Cool tools from a cool overnight open window will be covered with moisture when the warm morning air flows in.

The finished basement doors are closed to the toolroom and foyer. The dehumidifier is running in the boiler room which has 2 windows opened for fresh air flow. With summer approaching and humid days upon us is this the best set up? Thanks

Really.... when the humidifier is running the windows need to be shut. If it's a low humidity day you can turn off the humidifier and open the windows.

To be running the dehumidifier with the windows open is non productive.

Running the dehumidifier with the windows open means you're trying to dehumidify your whole neighborhood. Close the windows.
