Middle Tennessee's summers routinely push outdoor humidity above 85%. A commercial crawlspace dehumidifier is the only reliable way to keep your crawlspace below the 55% threshold where mold can't grow — regardless of what the weather is doing outside.
The big-box store sells dehumidifiers for $200–$400. Homeowners buy them, set them in the crawlspace, and feel like the problem is solved. Here's what actually happens:
A properly sized and installed commercial unit solves all of these problems — and typically lasts 10–15 years with annual filter maintenance.
We install and service Aprilaire E-Series dehumidifiers — the most trusted name in professional crawlspace dehumidification. Every model is designed specifically for the demanding conditions of below-grade sealed crawlspace environments.
Removes up to 70 pints/day. Compact design fits tight crawlspaces. Corrosion-resistant aluminum coils, built-in condensate pump, and automatic humidity sensing. Backed by a 5-year warranty and designed & assembled in the USA.
Removes up to 95 pints/day. One of Aprilaire's most energy-efficient models. Features interactive digital display, auto-defrost, and continuous auto-drain. Ideal for larger crawlspaces with higher humidity loads.
Removes up to 130 pints/day. Recognized as Most Efficient of ENERGY STAR®. High-capacity unit for large or heavily moisture-loaded crawlspaces, with MERV-8 filtration and flexible ducted or freestanding installation.
All units we install include auto-drain capability — water is pumped out continuously with no bucket to empty and no risk of the unit shutting off from a full reservoir.
Optional wired or wireless remote display lets you monitor crawlspace humidity from inside your home without ever opening the access door.
We offer an annual filter cleaning and performance check to keep your unit running at peak efficiency and catch any issues early.
In Middle Tennessee — almost always yes. A vapor barrier stops ground moisture (a big source), but humid air still enters through foundation vents, gaps, and the access door. A dehumidifier handles residual vapor and keeps humidity controlled regardless of outdoor conditions.
A commercial unit like the Aprilaire E100 uses about 700W at full capacity — comparable to a window AC unit. Most homeowners spend $15–30/month operating it. The HVAC savings from reduced humidity typically offset that cost entirely.
Barely noticeable, if at all. Commercial crawlspace units run at around 50–55 decibels — about the level of a normal conversation. In a fully sealed crawlspace, you typically can't hear it from inside the home.
Yes. We service and repair Aprilaire and other commercial-grade units regardless of who installed them. Call us to schedule a service visit.
