FAQs

Why is a whole-home dehumidifier important for controlling mold spores in Shelbyville?

Shelbyville’s warm, rainy springs and humid summers routinely push indoor relative humidity above 60 percent—the threshold at which mold spores thrive. A whole-home dehumidifier pulls moisture from the air before it circulates through your HVAC system, keeping humidity in the 30–50 percent range. By depriving mold of the moisture it needs, you protect your family’s health, reduce musty odors, and prevent costly damage to drywall, flooring, and furniture.

How does a dehumidifier integrate with my existing heating and air-conditioning system?

During installation, the dehumidifier cabinet is tied into the supply and/or return plenum of your central HVAC ductwork. As your air handler moves air, a dedicated fan inside the dehumidifier directs a portion of that airflow across a refrigerated coil that condenses excess moisture. The dry air is then returned to the duct system and distributed throughout your home. A condensate line safely drains the collected water to a floor drain or condensate pump. You operate the unit through its own humidistat or sometimes through a combined smart thermostat that manages both temperature and humidity.

What humidity level should I maintain to prevent mold growth?

National health agencies and building-science experts recommend keeping indoor relative humidity between 30 percent and 50 percent year-round. In Shelbyville’s climate, that usually means targeting 45 percent in summer and 35–40 percent in winter. Staying below 50 percent suppresses mold, dust mites, and bacterial growth, while levels above 30 percent prevent overly dry air that can irritate skin, sinuses, and wood furnishings.

How can I tell if my home has excess humidity or hidden mold spores?

Warning signs include persistent musty odors, fogged windows, visible condensation on HVAC vents, peeling paint, and dark spotting on walls or HVAC registers. You may also notice worsening allergy or asthma symptoms. A professional indoor air-quality assessment will measure relative humidity, take air samples for spore counts, and inspect ductwork, crawl spaces, and attic areas with moisture meters and infrared cameras to locate hidden mold sources.

What size dehumidifier does my Shelbyville home need?

Sizing is based on square footage, ceiling height, insulation quality, and typical moisture load from cooking, showers, and local weather. Most single-family homes in Shelbyville require units rated between 70 and 130 pints per day. Our technicians perform a Manual J-based moisture calculation to ensure the dehumidifier can keep up on the muggiest July afternoons without short-cycling or wasting energy.

How much maintenance does a professionally installed dehumidifier require?

Routine tasks are simple. Clean or replace the air filter every 3–6 months, inspect and flush the condensate line annually, and vacuum the exterior grille to remove dust. During your spring or fall HVAC tune-up, our Shelbyville technicians will check refrigerant pressures, calibrate the humidistat, and confirm that the drain trap is clear. With proper care, most whole-home dehumidifiers last 8–15 years.
