Crawl Space Dehumidifier

Choosing the right crawl space dehumidifier for your home

Helitech customers ask all the time “Why does my crawl space seem so musty even though I don’t have any water in the crawlspace?”.

The answer is simple, really. Most homes that are built over a crawlspace were designed with foundation vents that allow air to pass into the crawlspace from the outside – which is really a big problem that can lead to much larger issues than just a musty smell.

Your home’s crawl space provides easy access for plumbing, electrical, and structural repairs. But if proper precautions are not taken to prevent high humidity levels, your crawl space can easily become a breeding ground for mold, musty odors pests, and microscopic organisms which thrive in damp, dark, cold conditions.

A crawl space dehumidifier can help. It will remove excess moisture from your crawl space air and pump it outside to drain. Crawl space dehumidifiers improve not only the air quality of crawl space but of your entire home.

Keep this in mind if you don’t think that musty crawl space is a big issue … 50% of the air in your home comes directly from the crawl space. That’s right … at least 50% of what you and your family breathes comes from the crawl space. Any mold spores, mildew, bacteria, and dust mites that are in the crawl space are also in the air that you are breathing.

Dehumidifiers can prevent mold and water damage.

It’s a simple fix that protects the health of your home and family.

As the warm air from your living space rises and escapes through attic vents, the cold air from your crawl space travels upward to replace it. This is called the ”stack effect,” and it is why mold in your crawl space can spread upward to your home. And, because mold and microorganisms can aggravate your children’s asthma, allergies, and other respiratory conditions, it’s important to your family’s health to install a crawl space dehumidifier with a pump.

According to the Environmental Protection Agency, health problems associated with poor indoor air quality include eye irritation, allergies, headaches, and respiratory problems such as asthma. These problems can be directly related to the presence of mold and dust mite infestation in the home. One of the recognized solutions to addressing these health issues is effective moisture control.

Before you commence with a crawl space dehumidifier installation, though, you need to do your research. Here’s what to look for:

  1. The capacity of your dehumidifier to remove water from the air
    It seems that this should go without saying, but often people rush into buying the cheapest model without much research. High-quality de-humidifiers have high ‘gallons removed per day,’ meaning that they are able to remove quite a bit of moisture from your crawl space’s air. This is, after all, the chief purpose of your crawl space dehumidifier. In addition to reading product descriptions be sure to parse through Hydrabreeze crawl space dehumidifier reviews—as well as other brands—to see the real-life capacity of the dehumidifier as well.
  2. Your dehumidifier’s airflow
    In order to effectively reduce the relative humidity (RH) of your crawl space, all of your crawl space’s air must flow through the dehumidifier every couple of hours. To accomplish this, your dehumidifier must have a powerful fan and a high air flow as measured in CFM (cubic feet of movement per minute). Usually, you can look through crawl space dehumidifier reviews to see what past users have thought of the airflow. We use the HydraAir dehumidifier, which can remove an astonishing 110 pints per day. Most compact models provide only 70 pints per day of water removal.
  3. Look for a dehumidifier with a pump
    Unless you want to go into your crawl space every so often to empty your dehumidifier’s reservoir, it’s important to look for dehumidifiers that come with a pump. These pumps will direct the water removed from the air outside to drain away from your house.
  4. Installation company
    The crawl space dehumidifier installation company you choose is just as important as the actual equipment. In order for it to work, it needs to be installed correctly. Usually, your dehumidifier needs to be paired with a ventilation system, a vapor barrier, and a drainage system. Helitech can point you toward the right crawl space air system for your home.

At Helitech Waterproofing & Foundation Repair, our goal is to improve the health of your home. We’ll guide you toward the best solution for your home and family.


Helitech’s Compact HydraAir (formerly Hydrabreeze) Dehumidifier

How do we stop all of these issues and get ready for that nasty smell? Simple – with Helitech’s HydraAir dehumidification system.

Once a crawl space has been encapsulated or sealed off, Helitech can install a Hydrabreeze compact unit into your crawl space to reduce the humidity level and leave your home with conditioned air that not only smells better but is better for your family’s health.

The HydraAir compact unit is very small and is perfect for a crawlspace at only 12” x 12” x 21”. It can be hung with a Hydrabreeze joist hanging kit or placed on a level surface for use. It has an easy-to-set dial for desired humidity level as well as a switch to set the fan to auto or continuous use.

The Hydrabreeze unit will remove 70 pints per day, which is almost 9 gallons of water PER DAY. Keep in mind that all of that moisture and water vapor in your crawl spaces goes straight up through your home, so why wouldn’t you want clean low humidity air to breathe?

And the best part? No buckets to empty as the condensation water is discharged by the drain hose to a sump pit location or can be pumped directly outside with an added condensation pump attachment.

Mold particles are over 2 microns in size. The Hydrabreeze unit will take particles out of the air down to less than 2 microns, thus removing all mold particles and creating a clean breathing environment for you and your family.

For your home’s health, and more importantly your family’s health, we recommend all crawl spaces have a HydraAir unit to Heal Your Home’s air.

How Helitech’s Dehumidifier Works

The American-made, Energy Star HydraAir works in the simplest of terms by removing moisture from the air. This creates living spaces that are not only comfortable to you, but inhospitable to dust mites, mold, and other allergens.

This happens in a few easy steps:

  1. Humid air is pulled into the dehumidifier through the high-efficiency Merv air filter.
  2. It then passes over the evaporator coil. The cold surface of the evaporator coil, combined with the humid air, forces water to condense and droplets to form on the coil.
  3. This water then drops into the drain pan and runs out of the Hydrabreeze through the drain tube to an exit point.
  4. The now cold, dry air passes over the condenser coils and is heated to near room temperature. The conditioned air is then supplied to the basement or crawl space.

In these 4 easy steps, your home’s air is now below the recommended 50% relative humidity and you no longer have to worry about mold, dust mites, or those musty smells.

If needed, the HydraAir unit can also be fitted with a ducting kit to keep it out of sight in a storage room when the basement is finished.  

Just remember – 50% of the air you and your family breathe comes from your home’s crawlspace or basement. Choose HydraAir and heal your home’s air.

Kevin E. came out today to assess water damage in our basement. He was friendly, honest, and upfront on the work that needs to be done. He explained everything from the work scope to the payment breakdown. We feel the quote is reasonable (based on quotes from other competitors). I would definitely recommend Kevin and Helitech!
