Whole-House Dehumidifier Installation Solution in Hendersonville NC | Case Study
How an Aprilaire E100 System Eliminated Sticky Air and Protected Against Water Damage
A whole-house dehumidifier installation gives homeowners total control over indoor moisture levels during muggy mountain summers. When humid North Carolina weather hits, standard air conditioners often struggle to keep up. This leads to clammy indoor air, musty odors, and higher risks of mold growth.
Problem:
To solve high indoor humidity safely, three critical elements are required:
- Whole-Home Humidity Control: A system built right into your air ducts to clean and dry the air in every room, not just a single corner.
- Safe Water Drainage: High-powered dehumidifiers pull gallons of water out of the air every day. That water needs a clear path out of the home and a safety shut-off to prevent accidental leaks.
- Dedicated Power: Heavy-duty equipment needs safe, proper electrical wiring so it runs reliably without tripping breakers.
The Solution:
Aprilaire E100 System & Custom Safety Setup
📅 Install Date 📅: 11/18/2026
⏱️ Time to Complete⏱️: 10 Hrs
💵 Total Investment 💵: ~$4,000
Installed an Aprilaire Model E100 Dehumidifier paired with dedicated plumbing and custom safety controls.
- We connected an Aprilaire E100 directly into the existing ductwork to quietly pull excess moisture out of every room in the home, rather than just one isolated area.
- We ran sturdy PVC piping into an automatic drain pump that sends collected water outside, eliminating the need to empty heavy water buckets.
- We mounted a safety float switch on the drain pan that instantly shuts off power if the drain ever gets blocked, protecting floors and ceilings from standing water damage.
- We installed dedicated wiring with a GFI outlet designed specifically to handle heavy-duty appliances safely near water lines.
- We discounted about $300 off the project total through the Blue Ridge Service Agreement.

Why Was This Solution the Best Choice?
We chose the Aprilaire Model E100 because Aprilaire makes top-tier whole-home dehumidifiers, pulling up to 100 pints of moisture out of the air daily. Standard air conditioners only remove humidity while actively cooling. On mild, sticky days, the central AC shuts off early and leaves the house feeling damp.
The Aprilaire E100 runs whenever humidity rises—keeping air fresh and comfortable without over-cooling. By pairing this unit with a dedicated drain pump, an automatic flood-prevention float switch, and safe GFI electrical wiring, we made sure the system runs safely without any risk of water leaks or electrical shorts.
Best of all, the homeowner rests easy knowing the setup is completely covered by our 1-Year Labor Warranty and a 5-Year Aprilaire Parts Warranty.
4 Tips for Homeowners Dealing with Indoor Humidity & Condensate Systems
Target 30%–50% Relative Humidity
Keeping your home’s relative humidity in this sweet spot stops mold and dust mites in their tracks while keeping your air comfortable.
Never Skip Secondary Float Switches
Always make sure your dehumidifier or AC unit has an automatic overflow float switch. It’s a tiny part that can save you thousands of dollars in water damage repairs.
Clear Your Drain Lines Each Season
Algae and gunk naturally build up in drain lines over time. Pouring a cup of plain white vinegar down your primary drain line every few months helps keep water flowing freely.
Schedule Annual System Check-up
Dehumidifiers take a huge workload off your primary air conditioner, but both systems need regular check-ups. Yearly maintenance keeps filters clean, switches working, and equipment running efficiently before summer humidity sets in.
