Why Dehumidifiers Matter in St. Louis Summers
St. Louis summers are known for heat and heavy humidity. That moisture doesn’t stay outside — it can make indoor air feel sticky and uncomfortable, even when your A/C is running. During mild but muggy days in late spring and early fall, your system may not run long enough to remove excess moisture.
Humidity issues often appear first in basements, crawl spaces, and lower levels, especially in older brick homes, where dampness can linger after storms. A whole-house dehumidifier pulls moisture from the air before it settles, helping protect your home from moisture damage and humidity-related buildup.
If you’re noticing persistent moisture, our team can evaluate your home and recommend the right whole-house solution for steady, season-long control.
What to Expect from Dehumidifier Installation
Installing a whole-house dehumidifier is typically straightforward and designed to work with your existing HVAC system. Here’s what the process usually looks like:
- Home & moisture assessment: A thorough evaluation of areas where humidity tends to build up, including basements, crawl spaces, and lower levels, along with a discussion of your comfort goals.
- System recommendation: Selection of the right dehumidifier based on your home’s layout, moisture levels, and HVAC configuration.
- HVAC integration & placement: Professional installation in a location that allows effective moisture removal and even distribution of drier air throughout the home.
- Condensate drain setup: Proper routing of collected moisture to a suitable drain for clean, dependable operation.

Dehumidifiers FAQ
How do dehumidifiers cut down on energy costs?
Many people turn their air conditioners up when high humidity makes their homes feel muggy. However, the temperatures aren’t always hot enough to run the AC during spring and fall.
Whole-home dehumidifiers provide a more effective alternative by affecting the “real feel” temperature in your home. Humidity can counteract the cooling effects of air conditioning, making your home feel warmer than it actually is. This means you will be keeping your air conditioning system running longer without getting as many benefits from it as you should.
Dehumidifiers counteract this issue by removing moisture from the air, helping your air conditioner run more efficiently. This can help you significantly cut down the costs of heating and cooling your home.
Are dehumidifiers noisy?
Some dehumidifiers can be noisy, but one standout feature of the AprilAire system is its quiet operation. It effectively reduces excess moisture without adding unwanted sound to your home. With the AprilAire whole-home dehumidifier, you can maintain balanced humidity levels without interrupting sleep, work, or everyday comfort.
Can I install a dehumidifier in my home’s crawl space?
If your home has a crawl space, adding a dehumidifier can help keep that area dry and reduce musty odors. However, before installing an AprilAire whole-house dehumidifier, the crawl space should be properly sealed to prevent outside air from entering.
Without sealing the vents, an in-duct dehumidifier would constantly be trying to remove moisture from both the crawl space and the incoming outdoor air. Sealing the space first allows the system to work efficiently and maintain consistent humidity control.
Do I still need a dehumidifier if I have air conditioning?
Often, yes. Air conditioners cool the air, but they don’t always remove enough moisture, especially during mild but humid spring and fall weather, or in basements and crawl spaces. A whole-house dehumidifier manages humidity directly, helping your home feel less sticky and more comfortable.
What’s the difference between a portable dehumidifier and a whole-house dehumidifier?
A portable dehumidifier is designed to manage moisture in a single room and often requires frequent emptying or access to a nearby drain. In larger homes or multi-level spaces, it can be difficult to maintain overall humidity.
A whole-house dehumidifier, on the other hand, works with your HVAC system to remove excess moisture throughout the entire home. The result is more consistent humidity control, particularly beneficial for basements, crawl spaces, and humid St. Louis summers.
