What a crawl space dehumidifier install involves
The unit hangs under your house and takes moisture out of the air all season. Here is what it needs and what it can't do.
A unit made for a crawl space
Dylan installs crawl space dehumidifiers. A unit built for this space keeps working in the cool, damp air under a house, which a household dehumidifier isn't made to do.
A drain for the water it pulls out
A dehumidifier collects water as it runs. That water needs a continuous drain, by gravity or a small pump, or the unit stops when its tank fills.
Power at the unit
A unit running around the clock needs a dependable outlet nearby, and often its own circuit. Ask about power when you call, so the price covers it.
Where indoor humidity should stay
The EPA says indoor relative humidity should stay below 60%, and ideally between 30% and 50%. That is the range a crawl space dehumidifier works to hold.

A sealed space does the unit less work
A vapor barrier over the soil keeps ground moisture from reaching the unit's air in the first place.
Not a fix for standing water or rot
A wet or rotted crawl space gets standing water removal or wood rot repair first. A dehumidifier works on air, not on the ground.
