Where Should I Place A Attic Dehumidifier?
The attic can be a tricky place in the home to control humidity. Hot air rises, so all the humid and warm air moves to the attic, and without adequate airflow, it just sits there with no place to go resulting in dangerous mold, bugs, and water damage. While this may go unnoticed with undeveloped attics, it can pose an immediate problem with renovated attic spaces.
A portable dehumidifier designed for attics with many of the same qualities as one designed for a crawl space can be beneficial. You can install an attic dehumidifier into the HVAC system much like a whole-house dehumidifier.
Placing a dehumidifier in converted attic spaces can make spending time in the attic more pleasant and prevent damage to items placed in the room, making you more likely to return.
Insulating walls and sealing windows in the attic to prevent the outdoor elements from coming in through spaces under the roof can help prevent additional moisture. If the renovated attic has a bathroom, installing an extractor can be a big help.
