Is the use of dehumidifiers a solution to interior moisture problems?

Honest answer. No.

Dehumidifiers pull moisture out of the air. If there is a moisture problem: AC condensation or imbalance, plumbing, roof or foundation leak, unsealed drainage system, foundation overpour, or any other issues causing interior moisture or dampness then these problems should be dealt with directly. If a space requires a dehumidifier then it has a definite moisture problem that should be addressed first.

Dehumidifiers will not remove puddles of water from a floor or dry out wet carpet and should only be used if other moisture prevention measures have failed.
