FAQs
Why is excess indoor humidity such a common problem in Sequatchie?
The Sequatchie Valley’s humid subtropical climate brings long, muggy summers and abundant rainfall. Outdoor moisture easily infiltrates homes through crawl spaces, attics, and everyday activities such as cooking, showering, and even breathing. When your HVAC system is sized or run mainly for temperature control, it may not remove enough moisture, leaving relative humidity above the recommended 45–50 %. Persistent high humidity can lead to mold growth, musty odors, warped wood, higher cooling bills, and aggravated allergy or asthma symptoms.
How does a whole-home dehumidifier integrate with my existing heating and air-conditioning system?
A whole-home (also called ducted) dehumidifier is tied directly into your home’s return or supply ductwork. As air circulates through the HVAC system, the dehumidifier pulls a portion of that air across a cold coil, condensing and draining excess moisture to the outside or to a condensate pump. The dried, slightly warmed air is then sent back into the duct stream for distribution. The unit has its own humidistat so it only operates when indoor humidity exceeds the set point, working in tandem with—and independently from—your main air conditioner or heat pump.
What signs indicate I might need professional dehumidifier installation?
• Indoor relative humidity consistently above 55 % as shown on a hygrometer or smart thermostat • Condensation on windows and glass doors • Musty or mildew odors, especially in closets, basements, or crawl spaces • Visible mold or mildew on walls, ceilings, or around vents • Buckling hardwood floors or sticky doors and cabinets • Family members experiencing increased allergy or respiratory problems If two or more of these symptoms are present, a humidity assessment and dehumidifier quote are recommended.
How do I know what size dehumidifier my Sequatchie home needs?
Sizing is based on a combination of square footage, ceiling height, infiltration rate, number of occupants, and moisture sources such as crawl spaces or indoor pools. Whole-home units are rated in pints per day (PPD) of moisture removal. Most 2,000–3,000 sq ft homes in the valley require 70–100 PPD units, while larger or leakier homes may need 120 PPD or more. During our in-home evaluation, we measure current humidity levels, inspect building envelope tightness, and use ACCA Manual LLH guidelines to select a properly sized system so it runs efficiently without short-cycling.
What is involved in the installation process, and how long does it take?
1. Moisture audit and load calculation 2. Selection of dehumidifier brand and model (e.g., Aprilaire, Honeywell, Santa Fe) 3. Placement planning—typically in a mechanical room, attic, or crawl space 4. Connection to existing supply/return ducts or installation of dedicated duct runs 5. Condensate drainage to the outside, floor drain, or condensate pump with overflow protection 6. Electrical tie-in to a dedicated 120 V or 240 V circuit 7. Calibration of the onboard humidistat and integration with any smart-home controls Most standard installations are completed in one working day (4–8 hours). Crawl-space or complex ductwork jobs may require an additional day.
How much does a whole-home dehumidifier cost and will it lower my energy bills?
In Sequatchie, turnkey installation typically ranges from $2,200 to $3,800 for standard 70-100 PPD units and $3,800 to $5,500 for high-capacity or crawl-space encapsulation packages. Costs include equipment, labor, duct materials, electrical, condensate management, and a one-year labor warranty. By maintaining optimal humidity, your air conditioner doesn’t have to run as long to achieve comfort, often trimming 10–15 % off summer cooling bills. You also protect wood furnishings and deter mold remediation expenses, making a dehumidifier a cost-effective investment over its 10-15-year lifespan.
