FAQs
Why do homes in Gatlinburg often develop musty odors even when the heating and air conditioning system is running?
Gatlinburg’s location in the Smoky Mountains means we experience persistently high outdoor humidity most of the year. When warm, moisture-laden air seeps into a conditioned space and cools, it raises indoor relative humidity. Standard HVAC equipment is designed to control temperature first and will only remove moisture incidentally while cooling. If the air conditioner short-cycles or the furnace is running during mild, damp weather, excess moisture lingers, allowing mold, mildew, and bacteria to grow on coils, ductwork, and porous furnishings—exactly what produces that familiar musty smell.
How does a whole-home dehumidifier eliminate musty odors better than portable units or scented products?
A professionally installed whole-home dehumidifier is connected directly to your supply/return ductwork. It pulls air from the living space, strips out excess moisture over cooling coils that operate independently of your AC, and sends the dried air back through the ducts. Keeping relative humidity in the ideal 45-50 % range stops mold and mildew growth at the source and dries building materials, so the odor molecules they emit disappear instead of being masked. Portable dehumidifiers treat only one room and require constant emptying, while candles or sprays merely cover odors without tackling moisture.
Where will the dehumidifier be installed in my existing heating and air conditioning system?
In most Gatlinburg homes, we mount the dehumidifier in the mechanical room, crawl space, or basement—wherever the main HVAC air handler is located. A short section of insulated flex duct ties the dehumidifier to the return plenum, and a discharge collar sends the dried air back into the supply plenum or a dedicated supply line. A condensate drain is routed to an existing floor drain or condensate pump, and a humidistat is wired to your thermostat or installed as a separate wall control. The footprint is roughly that of a medium suitcase, so no major remodeling is required.
Will adding a whole-home dehumidifier increase my energy bills?
In many cases, homeowners see their total energy costs remain flat—or even decrease. By wringing out latent heat (moisture), the dehumidifier allows you to raise your thermostat setting 2-3 °F while still feeling comfortable, reducing air-conditioning run time. Modern units draw about the same wattage as a small window AC but remove 2–4 times more moisture per kilowatt-hour than portable units. Over an entire Gatlinburg summer, that efficiency plus less AC cycling often offsets the dehumidifier’s electrical use.
How much maintenance does a whole-home dehumidifier need?
Routine upkeep is simple. Replace or clean the internal air filter every 6–12 months, depending on dust levels. During your annual HVAC service visit, our technician will flush the condensate line, confirm refrigerant pressures, and verify the humidistat calibration. Coils are enclosed, so they stay cleaner than an air handler’s evaporator coil. With proper care, quality dehumidifiers last 10–15 years.
What is the installation process and how long will it take?
After an in-home assessment to size the unit (measuring square footage, ceiling heights, and infiltration rates), we schedule a single-day installation. Our crew: 1) sets the dehumidifier on vibration-isolating pads, 2) cuts and seals two 6- to 8-inch duct openings, 3) runs low-voltage control wiring to the thermostat or humidistat, 4) plumbs the condensate drain, and 5) commissions the system with a hygrometer to confirm target humidity. Most Gatlinburg homes are completed in 4–6 hours, and you’ll notice drier, fresher air within the first 24 hours of operation.
