Whole-Home Dehumidifier Installation & Repair

Do you think that your house is clammy, sticky, or damp, even when the air-conditioner is working? When the indoor humidity is excess of 60 percent, it favors development of mold and dust mites, develops stale odors, and may exacerbate allergies and asthma. Our whole‑home dehumidifiers remove humidity directly out of your ducts, rendering dew points to a healthy 55°F—without cooling your house too much.

Is Your Home Too Humid? A Guide for Our Service Areas

For those in moist climate zones such as Louisiana and Mississippi, or for people with hot, muggy summers like in Pennsylvania, Maryland, or the District of Columbia, a whole-home dehumidifier is essential.

Signs you might need a dehumidifier include:

  • Musty or mildew smell that persists.
  • Condensation on the interior of window panes.
  • Mold spots that can be seen on walls or ceilings.
  • A “damp” or “clammy” feeling on skin and furniture.
Tips You Won’t Find Elsewhere
  • Duct‑Line Freeze Protection: In colder zones (e.g., Nebraska winters), we install line‑heaters on condensate drains to avoid freezing up and preventing ice blockages – a step that every installer skips.
  • Dynamic Scheduling: Sensors signal the dehumidifier to run harder after showers or cooking but with less intensity in lower-humidity hours which conserves energy.
  • Dual‑Drain Options: We provide separate drains for basements and main floors, ensuring no area floods or backs up.
