Humidity Control Systems 
As humidity rises and falls, the soundboard shrinks and expands, causing the strings to raise or lower the pitch (creating sharpness or flatness in the pitch). Keeping the humidity constant keeps the piano in tune longer and avoids soundboard damage, like cracking.
How can I control the humidity in my home?
There are humidity control systems available for furnace/air conditioning units, as well as room humidifiers and dehumidifiers. While controlling the entire home environment is ideal, this is often not practical, so humidity control systems have been designed to fit inside your piano. These systems can be easily installed by a qualified technician, and with proper attention have proven to be most effective as they automatically stabilize the humidity levels.
Dampp-Chaser
Humidity and temperature affect all of the piano's parts. Extreme dampness and excessive heat are the greatest enemies of your piano. Strings and pins become rusted and corroded; bridge and soundboard damage can occur as well as pinblock damage. Although heavily coated with a protective finish, the soundboard is still vulnerable to seasonal changes.
In the spring, the wood in the piano absorbs the additional humidity in the air. As moisture settles into the soundboard, its crown increases creating more tension on the plate and strings, resulting in the piano going sharp in pitch.
To alleviate the great variations we experience with our constantly changing climate, we advise that you ask your technician about the possibility of having a Dampp-Chaser humidity control system installed to help prevent damage and maintain tuning stability in your piano.
The extra care taken to achieve correct humidity and temperature for the piano will be well worth the effort.
