How to Know Which Crawl Space Dehumidifier You Need
Humidity in crawl spaces and basements can become a concerning problem that causes poor air quality, mold and mildew growth, and expensive structural damage if left untreated. To prevent these problems, an HVAC professional would recommend investing in a quality crawl space dehumidifier to manage the excess moisture before it affects your home.
Before we dive into the top dehumidifiers for crawl space moisture control, it's important to know how to find a dehumidifier that fits your space. Some considerations would be the size of the space with the humidity problem, and the climate of your home. If the area is too small compared to the suggested room size of a dehumidifier, you may be over-consuming energy and increasing your electric bill. If the area is too large for the suggested room size of the dehumidifier, it will have a more difficult time maintaining the desired humidity.
The climate is also a very important factor to take into consideration. High-humidity environments such as coastal areas will likely need a dehumidifier with a higher pint capacity. Climates with extreme temperatures will also affect the dehumidifier if it is not built to operate in low temperatures.
