Crawl Space and Whole House Dehumidifiers in Suwanee, GA

What a Crawl Space Dehumidifier Does (and Why Georgia Homes Need One)

A crawl space dehumidifier pulls moisture out of the air under your house and keeps it at a dry, steady level so mold, rot and musty smells can't take hold. It runs on its own, drains to the outside and shuts off when the space reaches the humidity you set.

That matters more in North Atlanta than most places. Georgia summers are humid, and a lot of homes in Suwanee, Duluth, Lawrenceville and Johns Creek sit over a crawl space with ductwork running through it. Warm, wet air settles under the floor, soaks into wood and insulation, and rises into the rooms above. Your HVAC system pulls some of that air right into the ducts and blows it through the house.

The EPA recommends keeping indoor humidity between 30% and 50%. Many Gwinnett crawl spaces sit well above that from May through September. A properly sized crawl space dehumidifier brings that number down and holds it there, so the air you breathe upstairs starts drier and cleaner. Our guide to indoor humidity in Georgia breaks down the right level for each season.

Signs Your Home Has a Humidity Problem

High humidity in a house rarely announces itself with a leak. It shows up in small ways that are easy to blame on something else. Call us if you notice any of these:

• A musty or earthy smell that comes back after you clean
• Ducts or pipes in the crawl space that sweat or drip
• Damp, sagging or fallen insulation under the floor
• Mold spots on floor joists, baseboards or closet walls
• Rooms that feel sticky even with the AC running
• Allergy symptoms that get worse in summer

If you see visible growth or the smell is strong, start with mold testing so you know exactly what you are dealing with before anything gets installed. Not sure where the moisture is coming from? Our air quality testing measures humidity, particles and VOCs room by room.

Crawl Space vs Whole House Dehumidifier: Which One You Need

Both units remove water from the air. The difference is where they sit and which air they dry. Here is how we decide:

If the problem starts under the floor, a crawl space dehumidifier fixes it at the source. If the whole house reads high on our meter, a whole house dehumidifier works through your existing ducts to dry every room at once. Some homes need both: one to keep the crawl space dry and one to keep the living space comfortable. We show you the readings and tell you which one solves your problem, not the most expensive option.

Doesn't My AC Already Remove Humidity?

Some. Your air conditioner pulls moisture out while it cools, but only while it runs. On mild, rainy spring and fall days in Georgia the AC barely turns on, so the air stays cool and damp. That is when musty smells and sticky floors show up. A whole house dehumidifier works on its own schedule, drying the air even when the AC is off, so the house stays comfortable and your system doesn't have to run colder just to feel dry.

The same thing happens below the floor. Your AC never touches the air in the crawl space, so a crawl space dehumidifier is the only way to keep that space dry year round.

Our Dehumidifier Installation Process

Every dehumidifier installation follows the same air quality process we use on every job: test, inspect, then fix.

1. Test the humidity. We measure humidity in your living space and your crawl space so we start with real numbers, not guesses.
2. Inspect the space. We check the crawl space, ductwork and HVAC system and look for standing water, leaks and damaged insulation. The inspection is free with any service.
3. Size and place the unit. We match the dehumidifier to the size of the space and set it where air moves best, away from corners where damp air gets trapped.
4. Run the drain line. The unit drains to the outside or into your condensate line, so there is no bucket to empty.
5. Set your target. We set the humidity level for your home and show you how to read it.

Most homes get a dehumidifier installed in one visit. If your ducts run through a damp crawl space, ask about crawl space encapsulation at the same visit so damp crawl space air stops reaching your system.
