FAQs
Why is a whole-home dehumidifier important for indoor air quality in Shelbyville?
Shelbyville’s humid subtropical climate means outdoor moisture frequently infiltrates homes. Excess humidity fosters mold, dust mites, musty odors, and can make your AC work harder. A properly sized, duct-integrated dehumidifier removes this moisture before it circulates through the HVAC system, stabilizing indoor relative humidity between 40-50 %. This range inhibits biological growth, improves comfort at higher thermostat settings, and helps protect wood furnishings and building materials from warping or rot.
Will a dehumidifier increase or decrease my energy bills?
Most homeowners notice either a neutral effect or a modest reduction in total energy costs. By wringing out moisture, air feels cooler, allowing you to raise the thermostat 2-3 °F without sacrificing comfort. Your air conditioner then runs shorter cycles, saving electricity. High-efficiency whole-home dehumidifiers draw only 4–8 amps, far less than an AC compressor, so the added electrical use is typically offset by the AC savings and by preserving the efficiency of the HVAC equipment itself.
How is a whole-home dehumidifier installed with my existing HVAC system?
Our Shelbyville technicians mount the dehumidifier in a mechanical room, crawl space, or attic and tie it into the return or supply plenum. A dedicated return grille can also be added for balanced air flow. Condensate is piped to a floor drain or condensate pump. The unit is controlled by a digital humidistat, which can be integrated with smart thermostats or your home automation platform. Installation usually takes 4-6 hours and requires no major remodeling.
What size dehumidifier does my home need?
Sizing is based on square footage, ceiling height, infiltration rate, and the number of occupants. A 2,000 sq ft Shelbyville home generally needs a 70-90 pint-per-day unit, while a 3,500 sq ft house might require 120-135 pints. During our free in-home assessment we perform a load calculation similar to Manual J for moisture removal, ensuring the equipment can maintain 45 % RH on peak-humidity days without short-cycling.
How often does a whole-home dehumidifier need maintenance?
Maintenance is minimal: replace or rinse the internal MERV-rated filter every 6-12 months, clear the condensate trap annually, and keep the grille free of dust. During your routine spring or fall HVAC tune-up, our technicians also verify refrigerant charge (if applicable), clean the coil, inspect the blower wheel, and test the humidistat calibration. With proper care, units from leading brands such as Aprilaire or Honeywell typically last 10-15 years.
Can a dehumidifier help with allergies and musty odors?
Yes. Many Shelbyville residents experience seasonal allergies to mold and dust mites—both thrive above 60 % RH. By maintaining mid-40 % humidity, dehumidifiers dramatically reduce these allergen populations. Lower humidity also slows VOC off-gassing from carpets and furniture, eliminating that ‘damp basement’ or ‘old house’ smell. When paired with HEPA filtration or UV air purification, a dehumidifier forms a comprehensive indoor air-quality strategy.
