Whole-Home Dehumidifier Installation in Raleigh
Duct-integrated dehumidification for stable indoor comfort and controlled Relative Humidity. We target 45–50% RH for most homes in the Triangle region.
Request an EvaluationWhat a Whole-Home Dehumidifier Does
A whole-home unit removes moisture from indoor air through dedicated ductwork, keeping humidity consistent across the entire living space.
This is different from portable units. Properly installed ducted systems control RH without constantly emptying buckets, and they improve comfort and indoor air quality when humidity is driving odors, clamminess, or dust-mite activity.
When Whole-Home Dehumidification Makes Sense
It's the right tool when humidity is a house-wide problem — not just a single room problem.
- Summer humidity spikes even with A/C running
- Musty odor that spreads through the home
- Condensation on supply vents or windows
- Allergy-sensitive homes needing tighter RH control
- Tighter-envelope homes where ventilation affects humidity balance
How We Size and Install It
We size equipment based on moisture load, home volume, and how the HVAC system actually moves air — not a square footage guess.
We look at the building, the HVAC configuration, and the humidity sources. We also verify drainage and safe condensate routing so the system can run reliably long-term.
Humidity Sources That Make Systems Work Harder
If humidity is coming from below, it shows up indoors — especially through the Stack Effect pulling damp crawlspace air upward into living areas.
Warm air rising in the home creates a pressure pull that draws damp air from a crawlspace upward through gaps, floor penetrations, and duct leakage. If the crawlspace is wet, indoor RH can stay high even with good air conditioning.
When needed, we recommend crawlspace control measures like sealed vents and heavy-duty 12-mil or 20-mil vapor barriers to reduce moisture migration at the source.
What You Get
A system installed for performance, drainage, and serviceability — not a quick hookup.
Proper Duct Strategy
Dedicated return and supply routing as appropriate for your HVAC configuration and home layout.
Commissioning
RH target setup and verification at installation — so you know the system is working from day one.
Condensate Drainage
Gravity drain evaluation and sump options where needed. No buckets, no overflow risk.
Maintenance Guidance
Clear instructions for filter changes, seasonal checks, and RH verification over time.
Frequently Asked Questions
Will this replace air conditioning?
No. A whole-home dehumidifier controls humidity. Air conditioning controls temperature and removes some moisture, but not always enough in high-humidity conditions.
What RH should I target?
For most Triangle-area homes, 45–50% RH is the right target for comfort and moisture control.
Do I need a crawlspace fix too?
If crawlspace moisture is feeding indoor humidity, yes. A whole-home unit helps, but stopping the source is better long-term. We evaluate both during assessment.
How is water drained?
We plan a reliable condensate path — gravity drain when possible, with sump and pump options evaluated when needed.
