Frequently Asked Questions

Can I Install a crawl space dehumidifier myself, or do I need a licensed contractor to install it?

Most manufacturers won’t honor a warranty of a product that has been installed by an individual homeowner. However, the Moisture Medic® Crawl Space Dehumidifier warranty proudly covers both a DIY installation or a professional one. Whether you’re doing a Crawl Space Encapsulation® or using it in a basement, it can be installed by you or a licensed contractor.

What Size Dehumidifier Do I Need?

Crawl Space Dehumidifiers come in many sizes. Choosing the correct size dehumidifier depends on your crawl space and every crawl space is different. If a dehumidifier is too large for the space, the on-board controls will work against the productivity of the dehumidifier. One of the byproducts of running a crawl space dehumidifier is heat. Heat is not a bad thing when it is winter, but it is not a good thing when you are removing moisture from the air with a dehumidifier. A larger-than-needed dehumidifier in a crawl space will create excess heat and cause the dehumidifier to run shorter cycles. This can cause a shorter lifespan for the dehumidifier. Choosing the correct size dehumidifier for your crawl space will ensure you get the lifespan you expect.

How Often Do I need to Change the Filter?

After initial installation, you should allow 6 weeks for the unit to run. After 6 weeks, it is recommended that you check your filter. If it’s clean, check again monthly. After the first cleaning, you will be able to determine if you should check within a shorter or longer period of time. This all depends on how dirty the filter was during the first change. Each crawl space is unique in how often the filter of a dehumidifier has to be changed.

Does My Crawl Space Have to Be Encapsulated to Put in A Dehumidifier?

No, the Moisture Medic® dehumidifier is designed to run independently to control the humidity in your crawl space.

However, think of your crawl space as a room in your home you’re trying to keep warm during the winter. If you crack a window, the cold air will come in. Your heater will run and attempt to keep the room warm, but will be strained because of the unstable environment. A crawl space is no different. In order to get the most out of your investment and have your dehumidifier last its full lifetime, a full crawl space encapsulation is the best option.
