FAQs
Why is a whole-home dehumidifier important in Charleston’s climate?
Charleston’s coastal location brings year-round humidity levels that often exceed 60–70 percent. High indoor humidity promotes mold growth, dust-mite activity, warped wood flooring, and a muggy, uncomfortable feel even when the air conditioner is running. A properly sized whole-home dehumidifier removes excess moisture before it circulates through your ductwork, keeping relative humidity in the ideal 45–50 percent range, improving comfort, protecting furnishings, and allowing your AC to run more efficiently by focusing on temperature rather than moisture removal.
How do I know my home needs a dehumidifier?
Common warning signs include condensation on windows, musty odors, visible mold spots on walls or vents, clammy air, and persistent allergy or respiratory symptoms. You may also notice your air conditioner running constantly without effectively clearing the sticky feeling. Our technicians can perform a humidity audit using calibrated hygrometers to document readings in different rooms. If indoor RH consistently tops 55 percent, we’ll recommend the correct dehumidification solution.
What size dehumidifier do I need, and how is it calculated?
Whole-home units are rated by pints of moisture removed per day (PPD) or cubic feet per minute (CFM) of airflow. Sizing depends on your home’s total square footage, average outdoor humidity, infiltration rates, insulation levels, and existing HVAC capacity. We perform Manual J and room-by-room moisture load calculations along with blower-door testing when needed. The goal is to match the dehumidifier’s extraction rate to your home’s latent load while allowing it to cycle properly for energy savings.
Can a dehumidifier be integrated with my existing HVAC system?
Yes. Most modern whole-home dehumidifiers are ducted and can be tied directly into your supply or return plenum so that dry air is distributed evenly through existing vents. We also offer dedicated return setups with their own intake grilles for balanced airflow. Units feature automatic humidistats that communicate with your thermostat or smart-home system, ensuring seamless operation with your air conditioner or heat pump.
How long does professional installation take, and what is involved?
A typical installation takes 4–6 hours. Our licensed technicians begin with a pre-install inspection to confirm ductwork condition and electrical availability. We then place the dehumidifier—usually in an attic, crawl space, or mechanical room—install a condensate drain line with a fail-safe float switch, connect supply/return ducts, wire an external or integrated humidistat, seal all joints with mastic, and run a full operational test. We’ll review settings with you before leaving.
What maintenance is required after installation, and can your technicians handle it?
Whole-home dehumidifiers are low-maintenance but do require periodic care: filter replacement every 6–12 months, coil cleaning once a year, and verification that the drain line is clear. Our Comfort Club membership includes semiannual visits where we perform a 15-point inspection, clean the unit, sanitize the condensate pan, check humidity set-points, and document performance. Regular maintenance extends equipment life and keeps your indoor air healthy.
