FAQs
Why should I add a whole-home dehumidifier to my existing HVAC system in Shelbyville?
Middle Tennesseeâs long, muggy summers often push indoor relative humidity well above the recommended 45â55 % range. Excess moisture makes rooms feel hotter, encourages mold and mildew, and can warp hardwood floors or trim. A whole-home dehumidifier tied into your HVAC ductwork removes several gallons of water from the air every day, so you feel more comfortable at a higher thermostat setting, reduce musty odors, and protect your home and belongingsâall without the noise and hassle of portable units.
How is a dehumidifier installed and will it require major changes to my ductwork?
Our technicians mount the dehumidifier in line with your existing supply or return plenum and create a dedicated bypass so air can be drawn through the unit, dried, and delivered back into the main airstream. In most Shelbyville homes the job takes 4â6 hours and involves adding a condensate drain to a nearby plumbing line or condensate pump, wiring the control board to your HVAC system, and sealing new duct transitions. Because we use custom-fabricated fittings, modifications are minimal and your current heating and cooling performance is unaffected.
Will running a whole-house dehumidifier increase my energy bills?
The unit does use electricity, but lower humidity lets you raise the AC set-point by 2â3 °F and shortens compressor run-time. In many Shelbyville installations homeowners see a net drop or no change in monthly utility costs. Plus, drier air helps your HVAC equipment avoid corrosion and biological growth, reducing long-term repair expenses.
What size dehumidifier does my home need?
Sizing is based on square footage, ceiling height, typical occupancy, infiltration rate, and local weather data. A 2,000 ft² home usually needs a 70â90 pint-per-day unit, while larger or older homes may require 120 pint models. During a free in-home consultation we measure indoor humidity, inspect ductwork, and run Manual J calculations to ensure the dehumidifier matches both your HVAC airflow and moisture load.
How much maintenance does a whole-home dehumidifier require?
The system is largely set-and-forget. Plan on: ⢠Cleaning or replacing the air filter every 3â6 months. ⢠Flushing the condensate line annually to prevent clogs. ⢠Checking the RH set-point on the wall controller seasonally. During your spring or fall HVAC tune-up we also inspect the coil and blower wheel to keep performance at peak levels.
Can a dehumidifier improve allergies and indoor air quality?
Yes. Dust mites, mold spores, and bacteria thrive when RH exceeds 60 %. By keeping humidity in the recommended zone, a whole-home dehumidifier limits allergen reproduction, reduces musty smells, and helps your systemâs air filter capture smaller particles. Many Shelbyville customers report fewer sinus issues and less visible mold growth within weeks of installation.
