Why St. Louis & St. Charles Homeowners Need a Whole-House Dehumidifier This Summer
St. Louis summers are not subtle. The heat is one thing, but the humidity that comes with it is something else entirely.
What a lot of homeowners don’t realize is that that thick, sticky feeling inside your home isn’t just from the heat. It’s a moisture problem, and your air conditioner alone isn’t built to solve it.
During mild but muggy stretches in late spring and early fall, your AC may not run long enough to pull meaningful moisture from the air. The result is a home that feels damp, stuffy, and uncomfortable, even when the thermostat reads 72°.
A whole-house dehumidifier can take away that muggy feeling and leave you with a house that feels cool and refreshed, even in the St. Louis heat.
Where Humidity Problems Show Up First
Moisture doesn’t announce itself. It tends to settle in the lowest points of your home — basements, crawl spaces, and lower levels — where it lingers long after a storm passes. In older brick homes, which are common throughout the St. Louis area, that dampness can be especially persistent.
If any of the following sound familiar, humidity may already be an issue in your home:
-
- A musty smell in the basement or lower level
- Condensation on windows or glass doors
- That “wet basement” feeling, even when there’s no standing water
- Wood floors or trim that warp, swell, or feel soft underfoot
- Allergy or asthma symptoms that seem worse indoors
What Excess Moisture Actually Does to Your Home and Health
High indoor humidity isn’t just uncomfortable; it’s also damaging. When moisture levels climb above 50%, conditions become favorable for mold, mildew, and dust mites. For Missouri families with allergies or asthma, that’s a serious concern.
Beyond health, the structural toll adds up over time:
-
- Wood furniture, flooring, and cabinetry absorb moisture and deteriorate faster
- Clothing, linens, and stored items in damp spaces are more vulnerable to mildew
- Humidity counteracts your AC’s cooling effect, making the home feel warmer than it is and causing the system to run longer than it should
- Higher energy bills follow, because the AC is working harder without delivering full results
Choosing Between a Whole-House Dehumidifier or a Portable Dehumidifier
Portable dehumidifiers have their place — a single damp closet, a rarely used storage room. But for a St. Louis home? They fall short in a few important ways.
A portable unit manages moisture in one room at a time and requires frequent emptying. In a multi-level home, you’d need several of them running constantly to make a dent. Even then, the coverage is uneven.
A whole-house dehumidifier integrates directly with your existing HVAC system, and it consistently pulls moisture from the air throughout the home, without buckets to empty. Basements, crawl spaces, and upper floors are all covered with a whole-house dehumidifier.
What Types of Dehumidifiers Does Jones Air & Water Install?
Jones Air & Water installs whole-home dehumidifiers from Aprilaire, a brand known for reliability and quiet operation. These systems work with your existing HVAC system to remove excess moisture year-round, without the need for a separate unit or daily maintenance.
Aprilarie systems are designed for quiet operation. They won’t disrupt sleep or daily routines. The system runs automatically, maintaining indoor humidity within the recommended range of 30–50%.
If your home has a crawl space, it should be properly sealed before installation. Without sealing, the system would constantly work to prevent outside air from entering the space.
