The EPA's target is 30 to 50 percent indoor humidity and under 60 at most. We have no reported prices, so we do not quote a cost.

Start by measuring. The EPA says to keep indoor humidity below 60 percent, ideally 30 to 50 percent, and that a humidity meter costing $10 to $50 will tell you where you are (EPA mold and moisture guide).
If you are above it, look at the AC first: a clogged drain, a dirty coil or an oversized system that cools the air without running long enough to dry it. The EPA lists air conditioners and dehumidifiers as the tools to use when needed (EPA mold and moisture guide), and ENERGY STAR lists humidity control problems among the signs it is time to consider replacing the system (ENERGY STAR replacement guide).
A whole-home dehumidifier is the last step, not the first. ENERGY STAR says permanently installed units use central air ducts for multi-room dehumidification and work best in humid climates with central AC and consistently high humidity, above 55 percent, and that proper sizing, installation and home sealing matter. A certified unit uses 20 percent less energy than a standard one of similar capacity (ENERGY STAR dehumidifiers).
Simplified drawing, not to scale. Real systems vary: the indoor unit can sit in an attic or closet, the ducts can run in the attic or under the floor. Original illustration, not a photo.
ENERGY STAR sizes portable units by moisture level: 20 to 30 pints a day for small or medium rooms that are slightly damp, 25 to 50 for very damp conditions, and 30 to 50 or more for wet ones. It also says it is better to oversize than undersize (ENERGY STAR dehumidifiers). We cannot quote a whole-home price, so ask each installer for the model, its pint rating and the duct connection.
Before buying anything: buy a humidity meter, empty and clean the drip pan, check the drain line for a clog and replace the filter. Our drain page and short-cycling page cover the AC causes of a sticky house.

A clogged drain mostly leaks water. The EPA says AC drip pans and drain lines must stay clean and unobstructed to avoid mold (EPA mold and moisture guide).
The EPA says to keep indoor relative humidity below 60 percent, ideally between 30 and 50 percent (EPA mold and moisture guide).
Check the drain, coil and filter first. An oversized AC can cool the air without running long enough to dry it, and only a Manual J load calculation confirms the size. ENERGY STAR lists humidity control problems as a sign to consider replacement (ENERGY STAR replacement guide).
ENERGY STAR says whole-home units work best in humid climates with central AC and consistently high humidity, above 55 percent (ENERGY STAR dehumidifiers). Measure first.
These questions come from the topic clusters below in our research on 2,095 mined questions (Leaking / dripping water, clogged drain line: 101; Short cycling / turning on and off: 25; High humidity / muggy house: 15). The wording and answers are ours; we do not republish anyone's post.
