Indeed, a higher than average humidity coupled with the absence of light is the perfect reunion of conditions for mold, mildew and dirt growth. Not only that, but insects like ants, termites or other nefarious creatures find these conditions perfect for reproduction, which of course is very problematic, especially in the summer.

A dehumidifier fit for crawlspaces has to have an extremely large capacity, be easy to install while very hands-off in the long run (no one really wants to have to access to their crawlspaces on a regular basis), and an excellent value.

On the other hand, it can be less aesthetically pleasant than other domestic units, and a little more noisy. Even though it never hurts to have a beautiful and silent one!

Crawl Space Dehumidifier: Frequently Asked Questions

If the crawl space of your house is musty and moldy, then it is likely that the level of relative humidity is above acceptable margins. High levels of water vapor in a crawl space not only encourage growth of molds and mildew but it can also ruin the environment of your entire house.

If you have been trying to improve the environment of your room without success, then the problem could be emanating from your crawl space. A crawl space dehumidifier pulls excess moisture from the crawl space of your house to ensure that it has an environment that is unsuitable for fungal growths.

Maybe you are looking for a suitable dehumidifier for your crawl space and you are researching in order to make a well informed decision. Crawl space dehumidifiers come in different sizes, shapes, and capacities, and it is, therefore, important to consider various factors before ordering a unit for your space.

The following list of frequently asked questions will provide you with most of the information that you need to know about these dehumidifiers.

Why do I need a dehumidifier in my crawl space?

Excess moisture in a crawl space encourages growth of mold and mildew and also creates a good environment for the breeding of insects. To prevent this, it is necessary to ensure that the relative humidity of your crawl space is within the recommended range.

A crawl space dehumidifier pulls excess moisture from your crawl space to create an environment that discourages growth of these living organisms. Considering the damages that excess moisture can cause, it is necessary to ensure that you have a suitable dehumidifier in your crawl space.

Can a crawl space dehumidifier help to control pests?

Most pests prefer dark spaces that have high levels of moisture. If your crawl space has damp conditions, then it is providing pests with the ideal environment that they require for breeding.

Pests (dustmites in this case) are more easily attracted by humid environments.

Pests (dustmites in this case) are more easily attracted by humid environments.

If you have been trying to control pests in your house with little or no success, then it is likely that you have been attacking the wrong target. To eliminate them, you should attack their breeding places.

A dehumidifier will help to destroy their breeding space by removing excess moisture from your crawl space.

How can I estimate the capacity that is suitable for my crawl space?

Crawl space dehumidifiers are available in different sizes, capacities, shapes, and designs. If you select a low capacity dehumidification solution for your large crawl space, then it may be unable to effectively pull excess moisture.

For best performance, the capacity of your dehumidifier should match with the size of your space. Most manufacturers will provide you with an estimate of the size that they recommend their product for. This can help you to determine the capacity that is suitable for your crawl space.

Apart from capacity, you should also ensure that there is enough space to accommodate the dehumidifier that you intend to order. Most crawl spaces are narrow and they cannot accommodate large dehumidification units.

Since manufacturers understand the conditions of most crawl spaces, they ensure that their units are compact and rugged. Even if your crawl space is narrow, you can still get a suitable dehumidification solution for it.

Where does the captured water go?

If your house has a large crawl space, then it is likely that your dehumidifier will pull several pints of moisture from it. The amount of water captured by your dehumidifier will also greatly depend on the humidity of your surroundings.

Most crawl space dehumidifiers have a pumping mechanism that allows them to pump the captured water to an external sink. Such systems are suitable for underground spaces. Some units lack a pumping mechanism and they are designed to use gravity. The water captured by a dehumidifier is unsuitable for consumption, but you can use it for other purposes such as watering your flower beds, lawns, and trees.

How much electricity does a dehumidifier consume?

The energy needs of a dehumidifier mainly depend on its capacity, design, and features. High capacity dehumidifiers consume more electricity than low capacity systems. They are, therefore, likely to cause a bigger impact on your electricity bill.

To cut electricity consumption, it is advisable to limit the operating hours of your unit. You should consider the conditions of your crawl space and the relative humidity of your surroundings when planning such a schedule. In addition, to minimize energy wastage, you should select an Energy Star rated system. Energy Star rated dehumidifiers are optimized to consume minimum energy. Such a dehumidification system will help you to save money.

What is the cost of operating a dehumidifier in my crawl space?

The cost of operating a dehumidifier mainly depends on the number of hours that it is operating in a day and its capacity.

If your unit is running throughout, then the cost of running it is likely to be higher because it parts will wear more quickly. Unless you live in a high humidity environment, it may not be necessary to run your dehumidifier throughout. You can prolong the life of your dehumidifier by limiting the number of hours that it operates in a day.

Does the unit produce noise?

The amount of noise produced by a dehumidifier varies from one model to another. Some models produce irritating sounds while others are whisper quiet. Although it is unlikely that the sound of your crawl space dehumidifier will cause noise interference, it is important to consider this factor when selecting a dehumidification solution for your space. However, this should not be a key consideration.

Can I use an ordinary dehumidifier for my crawl space?

The ordinary dehumidifier is not a suitable choice for your crawl space. Unlike a crawl space dehumidifier, an ordinary unit is not designed to fit in crawl spaces. The compactness and ruggedness of crawl space unit makes it an ideal choice for your tight and damp spaces.

If you are planning to buy a crawl space dehumidifier, we hope you now have all the information that will enable you to select a suitable dehumidification solution for your space.
