Mold growth, musty odors, and structural damage are just a few of the problems that can result from too much moisture in a crawl space. To combat such issues, choosing the right size of dehumidifier for your crawl space is crucial. Here’s how to choose a dehumidifier for the underside of your home:
1. Assess the Size and Condition of Your Crawl Space
Before purchasing a dehumidifier, evaluate the dimensions and conditions of your crawl space. Measure the square footage to determine the appropriate capacity for your dehumidifier. Additionally, consider the humidity levels and any signs of dampness or water damage.
2. Understand Dehumidifier Sizing
Dehumidifiers are sized based on their moisture removal capacity, measured in pints per day. Manufacturers specify the square footage that a dehumidifier can effectively cover. According to experts, for crawl spaces, the recommended capacity ranges from 70 to 155 pints per day, depending on the size and sealing of the area.
3. Consider the Sealing of Your Crawl Space
The level of sealing in your crawl space will impact the size of the dehumidifier you need. According to professionals, loosely sealed crawl spaces require dehumidifiers with a capacity of up to 1,800 square feet. In comparison, moderately and tightly sealed areas can have capacities of up to 2,600 and 4,400 square feet, respectively.
4. Assess Additional Factors
There are a few other aspects to consider when choosing the right dehumidifier size for your crawl space. These include the climate in your region, the number of people occupying the space, the presence of doors and windows, and the proximity of appliances like washers and dryers.
Adjust the dehumidifier capacity accordingly, adding 10 pints for humid climates. You should also add 5 pints if your crawl space has multiple windows or doors, or if there’s a dryer or washer nearby.
5. Consider Desiccant Dehumidifiers
In some cases, traditional compressors and refrigerant dehumidifiers may not be suitable due to freezing temperatures or difficult drainage. Desiccant dehumidifiers are recommended for such scenarios. Such units use moisture-absorbing materials to extract humidity without relying on refrigeration, making them ideal for crawl spaces with specific challenges.
6. Seek Expert Advice
If you’re unsure about the size and specifications of the dehumidifier needed for your crawl space, consult with professionals in the field. They can assess the underside of your home and provide personalized recommendations to ensure optimal moisture control.
