Where should the dehumidifier be placed in the crawl space?

Proper placement of a dehumidifier in your crawl space is crucial for maximizing its efficiency and effectiveness in moisture control. 

1. Choose a Central Location
Select a central spot in the crawl space for your dehumidifier. This location allows for better air circulation and enables the unit to effectively dehumidify the entire area. Avoid placing it too close to walls or obstructions, as this can restrict airflow.

2. Ensure Proper Drainage
If your dehumidifier has a continuous drainage option, position it near a floor drain or a sump pump. This setup allows for easy drainage of collected water, preventing overflow and ensuring consistent operation without frequent tank emptying.

3. Maintain Adequate Clearance
Keep at least a few inches of clearance around the unit to promote airflow and prevent overheating. Ensure that no objects are blocking the intake and exhaust vents, as this can hinder the unit's efficiency.

4. Consider Humidity Levels
Place the dehumidifier in the area of the crawl space where humidity levels are highest. Use a hygrometer to monitor moisture levels and adjust the placement as needed. 

5. Avoid Extreme Temperatures
Ensure that the dehumidifier is placed in a location that avoids extreme temperatures. While most commercial dehumidifiers are designed to operate in a range of conditions, excessively cold or hot environments can affect performance. Ideally, keep the unit in a temperature range between 50°F and 90°F.

6. Install on a Stable Surface
Position the dehumidifier on a stable, level surface to prevent vibrations and noise. Avoid placing it directly on dirt or damp surfaces, as this can introduce moisture into the unit and affect its performance.

7. Use Multiple Units if Necessary
In larger crawl spaces or areas with significant moisture issues, consider using multiple dehumidifiers to ensure comprehensive coverage. This approach allows for better control of humidity levels throughout the space.


By carefully selecting the placement of your Airecoler commercial dehumidifier in the crawl space, you can significantly enhance its efficiency and effectiveness. Proper positioning not only improves moisture control but also contributes to a healthier environment, safeguarding your home from mold, mildew, and other moisture-related issues.
