FAQs

Why is excess indoor moisture a common issue in Louisville?

Louisville experiences hot, humid summers and frequent rainfall, which means outdoor humidity routinely creeps above 70 %. That moisture infiltrates homes through open windows, doors, crawlspaces, and even the slab or basement walls. When indoor relative humidity stays above 50 – 55 %, you can see mold growth, musty odors, warped wood floors, peeling paint, and aggravated allergy or asthma symptoms. A dedicated, whole-home dehumidifier keeps humidity in the optimal 40 – 50 % range, protecting your health, furnishings, and the structural integrity of the house.

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

A whole-home dehumidifier is hard-ducted into your supply and/or return ductwork, typically near the air handler. When the built-in humidistat senses humidity above your set point, the unit draws air from the return plenum, removes excess moisture by passing it over a refrigerated coil, and sends the drier air back through the supply ducts. Condensate drains safely to a floor drain or condensate pump. Because the unit shares the duct network, every conditioned room benefits, and your central HVAC blower distributes the dehumidified air uniformly without the need for multiple portable devices.

What signs indicate I should consider professional dehumidifier installation?

You may need a dehumidifier if you notice: • Persistent condensation on windows or supply vents • Musty or “basement” odors that linger even after cleaning • Visible mold or mildew on walls, ceilings, or HVAC registers • Buckling hardwood floors or peeling wallpaper • A sticky, clammy feel indoors even when the A/C is running • High indoor humidity readings (over 55 %) from a hygrometer. If any of these conditions appear, scheduling a moisture assessment and load calculation will confirm whether a whole-home dehumidifier is the right solution.

How do professionals determine the correct dehumidifier size for my home?

Sizing is based on square footage, typical moisture load, number of occupants, infiltration rates, and the presence of moisture sources such as crawlspaces or unfinished basements. Technicians perform a Manual J or similar load calculation, measure indoor humidity levels, and inspect duct design. Whole-home units are rated in pints of moisture removal per day (ppd); most Louisville homes require 70 – 120 ppd systems, while larger or older homes with crawlspaces may need 135 ppd or more. Proper sizing ensures efficient operation, prevents short-cycling, and minimizes energy costs.

What is involved in the installation process and how long does it take?

After the moisture assessment, installation generally takes 4–6 hours. Steps include: 1) Selecting a mounting location near the air handler or in a conditioned crawlspace/basement. 2) Cutting into supply/return ducts and attaching insulated flex or rigid duct runs. 3) Installing a dedicated 120 V or 240 V electrical circuit if required. 4) Adding a condensate drain line with an air-gap or trap, plus an overflow safety switch. 5) Integrating controls—a wall-mounted humidistat or smart-thermostat interface. 6) Testing airflow, refrigerant pressures, and condensate drainage. The crew will also show you filter access and control settings before departure.

How do I maintain my dehumidifier, and what lifespan should I expect?

Routine maintenance is simple: • Replace or clean the air filter every 3–6 months. • Flush the condensate line annually to prevent clogs and algae. • Vacuum the exterior and inspect duct connections for leaks. • Have a licensed HVAC technician perform a yearly check-up that includes refrigerant pressure, coil cleanliness, and electrical testing. With proper care, high-quality whole-home dehumidifiers last 10–15 years. Regular maintenance not only extends lifespan but also keeps energy consumption low and ensures your indoor humidity stays within the recommended range all year.
