Understanding crawl spaces
Crawl spaces are typically found beneath houses and serve as an access point to various utility systems, such as plumbing and electrical work. They are spaces that are not tall enough for a person to stand up, but rather require crawling or crouching to navigate. Crawl spaces play a crucial role in maintaining the structural integrity of a building by providing a dry and stable environment. By creating a barrier between the ground and the structure, crawl spaces help prevent moisture from seeping into the foundation and causing damage.
Common issues in crawl spaces
Crawl spaces can be prone to a range of issues that can impact the overall health and stability of a home. One of the most common problems is excessive humidity. Moisture can enter the crawl space through the ground or via leaks in pipes and ducts, leading to increased humidity levels.

Mold growth can also weaken the structural integrity of the building, potentially leading to costly repairs. Additionally, excessive moisture can attract pests such as termites and rodents, further jeopardizing the stability of the structure. By effectively controlling crawl space humidity, homeowners can protect their investment and ensure the health and safety of their living environment.
Introduction to dehumidifiers
Dehumidifiers are essential tools in controlling and maintaining crawl space humidity. These devices work by removing excess moisture from the air, effectively reducing humidity levels and mitigating the risks associated with excessive moisture. Dehumidifiers are specifically designed to target crawl space environments, offering a range of benefits and advantages over traditional methods of moisture control.
Definition and function of dehumidifiers
A dehumidifier is a device that extracts moisture from the air, reducing the humidity levels in the surrounding environment. It typically consists of a fan, a refrigeration system, and a water collection reservoir. As air passes through the dehumidifier, it comes into contact with the refrigeration system, causing the moisture to condense and collect in the reservoir. The drier air is then released back into the crawl space, effectively lowering humidity levels.
Types of dehumidifiers
There are two main types of dehumidifiers commonly used in crawl spaces: refrigerant-based dehumidifiers and desiccant dehumidifiers. Refrigerant-based dehumidifiers are the most common and work by cooling the air, causing the moisture to condense. Desiccant dehumidifiers, on the other hand, use a moisture-absorbing material to extract moisture from the air. Each type of dehumidifier has its own advantages and limitations, and the choice depends on the specific needs and conditions of the crawl space.
How dehumidifiers work
Dehumidifiers utilize the principles of condensation and evaporation to remove moisture from the air. The fan inside the dehumidifier pulls air from the crawl space, passing it through the refrigeration system or the desiccant material. In refrigerant-based dehumidifiers, the air is cooled below its dew point, causing the moisture to condense into liquid form. The liquid is then collected in the reservoir, while the drier air is reheated and released back into the crawl space. Desiccant dehumidifiers, on the other hand, use a rotating wheel or cartridge coated with a moisture-absorbing material. As the air passes through the desiccant material, the moisture is absorbed, resulting in drier air being released into the crawl space.
