FAQs
Why does my Louisville home need a whole-home dehumidifier?
Louisville’s Ohio River Valley climate delivers long, muggy summers and shoulder seasons with frequent rainfall. Indoor humidity often climbs well above the ideal 45-50 % range, leading to musty odors, sticky air, mold growth, and overworked air-conditioning equipment. A whole-home dehumidifier removes excess moisture from every room, improving comfort, protecting wood floors and furnishings, and reducing the chance of allergy-triggering mold and dust mites.
How does a whole-home dehumidifier integrate with my existing heating and air-conditioning system?
During installation we tie the dehumidifier into your home’s central return or supply ductwork, allowing it to treat all the air that moves through your furnace or air handler. A dedicated drain line sends the collected water to a floor drain or condensate pump, and a smart control panel or your existing thermostat manages humidity setpoints. Because the unit works in parallel with your HVAC system, you get balanced moisture control without sacrificing airflow or temperature comfort.
What size or capacity dehumidifier will my house require?
Capacity is determined by square footage, ceiling height, typical indoor moisture load, and infiltration levels. Most Louisville homes need a unit rated between 70 and 120 pints per day. During our free in-home evaluation we perform load calculations using ACCA Manual H guidelines, inspect duct sizing, and measure indoor RH levels. This ensures you receive a properly sized system—too small won’t keep up on 90 °F/75 % RH days, while too large wastes energy and short-cycles.
How long does installation take, and will it disrupt my home?
A standard whole-home dehumidifier installation is completed in one day—often 4–6 hours. Our licensed technicians: 1) shut off HVAC power, 2) cut in a supply/return bypass or dedicated duct run, 3) set and level the dehumidifier on vibration-isolating pads, 4) connect sealed duct collars, 5) run a PVC/CPVC condensate drain with proper trap, and 6) wire the unit to 120 V or 240 V power and the humidity controller. We protect floors with drop cloths, wear shoe covers, and test the system before we leave, so disruption is minimal and cleanup is complete.
What maintenance will my new dehumidifier require after installation?
Whole-home units are low-maintenance but not maintenance-free. Plan on: • Replacing or cleaning the dehumidifier’s MERV-rated pre-filter every 6–12 months. • Checking and clearing the condensate drain line at the start of each cooling season. • Verifying the RH setpoint on the control (most homeowners keep it at 45 %). During our annual HVAC tune-up we include a dehumidifier inspection, coil cleaning, and performance test to ensure peak efficiency.
Will a whole-home dehumidifier increase my energy bills?
The dehumidifier does draw power—typically 5–8 amps while running—but most Louisville homeowners see a net energy benefit. By removing latent heat, the air feels cooler, allowing you to raise the AC thermostat 2-3 °F without sacrificing comfort. Less runtime on your air conditioner also means lower wear and tear. The result is often a 5-10 % reduction in summer cooling costs, plus the added savings of preventing moisture-related repairs to wood trim, drywall, and electronics.
