Best Crawl Space Dehumidifier Benefits

Crawl spaces are found underneath the living space of a house. They are usually built on the ground level, but some homes have them in attics or basements. Crawl spaces provide an area for ductwork and other utilities to pass through.
Due to their location, they can also be prone to moisture problems because there is no barrier between the crawl space and outside air where water vapor settles due to heat transfer from indoor heating coils or coolers.
Consequently, dampness accumulates inside the crawl space which leads to mold growth as well as wood rot that can damage your home’s foundation and beams supporting your roof structure. To protect against these dangers, you should install a good quality dehumidifier in your crawl space during cold weather months, which is the time when humidity is at its highest.
How To Choose A Crawl Space Dehumidifier

When choosing the best crawl space dehumidifier for your home’s needs, you have many considerations to take into account. There are numerous brands and types available on the market today, so it’s important to identify your needs and preferences before you decide which dehumidifier to buy.
It is important to keep in mind that crawl space dehumidifiers come as either mobile or stationary types. Mobile dehumidifiers are best for those who want to remove excess moisture from their crawl spaces but can’t afford extra equipment like a blower or a duct.
They simply need to be plugged into an outlet and they can get rid of moisture fast with no hassles. Stationary dehumidifiers include more features such as humidistats and condensate pumps, making them better for those who want added control over their dehumidifying units.
Finally, there are two sizes of dehumidifiers for crawl spaces: the 10 to the 30-pint dehumidifier and the 30 to 50-pint. The lower capacity (10 to 30-pint) is more suitable for small spaces while the larger capacity (30 to 50-pint) is great for bigger areas like garages and storage rooms.
How To Use A Crawl Space Dehumidifier
Once you have selected a crawl space dehumidifier, properly using it is important for preventing any mishaps from happening. Always read the manufacturer’s user manual thoroughly before starting to use your new unit.
Then, plug it in and position it right over the area with the most moisture and remove any obstructions like furniture or boxes. Finally, turn it on and let it do its work by removing water vapor from inside your crawl space.
Crawl Space Dehumidifier tips
While dehumidifiers are considered one of the best solutions for preventing moisture problems in crawl spaces, there are some tips you should follow to ensure proper use.
First, before starting your dehumidifier, it is important that you address insulation problems. If rubbish or construction materials are packed around your unit, remove them carefully so as not to damage it and add more insulation instead. Also, check your crawl space vents to ensure proper ventilation.
After that, keep in mind that running your dehumidifier on the highest setting may damage it if it’s not designed for continuous operation. Thus, you should choose low-speed settings when possible and monitor the humidity levels in your crawl space in order to avoid problems.
Finally, make sure that your crawl space dehumidifier is switched off and unplugged when cleaning or moving it. Also, note that using a ground fault circuit interrupter (GFCI) with the cord of your unit will provide added protection against electrical shocks. Afterward, place it back in its original position and turn it on again.
Factors To Consider When Choosing Best Crawl Space Dehumidifier

Choosing the best crawl space dehumidifier is no easy task. There are lots of things to consider and it can be hard to know where to start. The wrong choice could lead to expensive repairs or even significant mold problems down the line. But with a little care and consideration, you can avoid these possible pitfalls and find an option that will work well for your needs without breaking your budget.
Here are 4 things you should consider when choosing a crawl space dehumidifier.
Size of the Crawl Space
First, you need to determine how large your crawl space is. There are different sized models for different sized spaces. You don’t want to go bigger than you need, but it’s also important not to go too small. Just because you can find one for a smaller space doesn’t mean it will work as well as a model designed for medium-sized spaces.
Electrical Outlet
The next thing to consider is whether or not the crawl space dehumidifier requires an electrical outlet. If there isn’t one, then it may be best to look for a different option or just forego the dehumidifier altogether. However, some units can be connected to an outlet and then unplugged and moved on a whim. This can really come in handy if you’re doing solar panels
Drainage System
You’ll also want to consider whether or not your crawl space already has a drainage system. If not, installing one may be required to use the crawl space dehumidifier. Without it, you run the risk of water accumulating on your floor and causing serious damage. Installing one doesn’t take long with the right tools, though, so it’s still worth considering this option if you aren’t sure if your crawl space has one.
Brand Name
When you’re looking for a crawl space dehumidifier, it’s also important to consider the brand name that makes it. Like with anything else you buy, some brands are better than others. You can find some great models made by Fortin Electric, which is one of the top manufacturers in the industry.
