I have recurring mold problems in the basement of my Raised Ranch house.

Should I still get a humidifier - for the winter months when the heat is running? IS this a must have?
Would it help for the house to be drier w/o a humidifier - so that the mold isn't as much of a problem anymore atleast in Winter and in summer ofcourse the A/C will hopefully dehumidify enough -

I probably still need to run a separate "de-humidifier" in the basement during summer.
thanks yall
