FAQs

Why should I add a whole-home dehumidifier to my HVAC system in Sevierville?

Sevierville sits in the foothills of the Great Smoky Mountains, where summer dew points often hover in the upper 60s and 70s. High indoor humidity encourages mold and dust-mite growth, aggravates allergies, makes your home feel warmer than the thermostat reading, and can warp wood floors and cabinets. A whole-home dehumidifier tied into your HVAC ductwork automatically removes excess moisture from every room, keeping relative humidity in the ideal 45–55 % range. The result is healthier air, reduced musty odors, and lower cooling bills because your air conditioner no longer has to over-cool just to dry the air.

How do I know what capacity dehumidifier my house needs?

Proper sizing is critical. Our comfort specialists perform a moisture load calculation that looks at square footage, ceiling height, insulation levels, air-leakage rates, the number of occupants, and typical indoor RH levels. Residential units are usually rated between 70 and 130 pints per day. An undersized unit will run continuously and still leave the home damp, while an oversized one will short-cycle and waste energy. We use ACCA Manual J data and on-site hygrometer readings to select a model that matches your home’s exact requirements.

How is a dehumidifier integrated with my existing heating and air-conditioning equipment?

The dehumidifier is installed in the return or supply plenum of your duct system, allowing it to treat the entire air stream. A dedicated condensate drain line is run to a floor drain or condensate pump, and we add an overflow shut-off switch for safety. The unit is controlled by its own humidistat or by your Wi-Fi smart thermostat if compatible. Because it has its own fan, it can operate independently of the air conditioner, pulling moist air through the filters, cooling coil, and dehumidifier media before delivering dry air back through the supply ducts.

Will the installation be disruptive and how long does it take?

A typical whole-home dehumidifier installation takes 3–6 hours. We begin by covering work areas with drop cloths and isolating the HVAC closet or attic to keep dust contained. Power to the air handler may be off for an hour while we make duct connections and run control wiring. Most homeowners experience minimal disruption and can remain in the house. After installation, we test the condensate drain, set the humidistat, and show you how to monitor RH levels from your thermostat or phone.

What kind of maintenance does a whole-home dehumidifier require?

Maintenance is straightforward: 1) Replace or clean the dehumidifier’s MERV-rated filter every 3–6 months; 2) Flush the condensate drain line with a mild vinegar solution twice a year to prevent clogs; 3) Have the evaporator coil and blower wheel cleaned during your annual HVAC tune-up; and 4) Verify the humidistat calibration annually. Many models feature internal sensors that alert you or our service team if airflow is restricted or if RH levels fall outside the set range. Enrolling in our Comfort Club means we handle all scheduled maintenance and provide priority service if repairs are ever needed.

How much does a professionally installed dehumidifier cost, and are there rebates for Sevierville homeowners?

Installed prices in Sevierville generally run $1,800–$3,500 depending on capacity, duct modifications, and whether a condensate pump is required. EnergyRight, the TVA program serving Sevier County Electric System customers, periodically offers rebates for qualifying ENERGY STAR® whole-home dehumidifiers. In addition, the federal 25C Inflation Reduction Act tax credit can cover up to 30 % of the cost (capped annually) when the unit meets specific efficiency thresholds. Because reduced humidity allows you to raise your thermostat 2-3 °F, many families see a 10-15 % drop in summer cooling costs, speeding payback on the investment.
