Yes, it's generally recommended to run a dehumidifier in your crawl space all year. While is higher in warmer months, moisture can still build up in cooler seasons. Continuous dehumidification helps prevent mold, wood rot, and other moisture-related problems.

To select the right dehumidifier, consider the size of your crawl space (square footage) the average humidity level, and the severity of moisture issues. A larger space or significant moisture problems may need a higher-capacity dehumidifier, measured in pints of water removed per day. Waykar offers crawl space dehumidifiers with capacities of 158 pints and 130 pints.
