If possible in warmer climates keep the air-conditioning at a constant temperature below 75 debrees. Humidity can also cause strings to become rusty. } Humidity caused the felt hammers and dampers to swell and may lead to “sticky keys” or keys that do not come back after struck.

As humidity goes up, a soundboard swells, increasing its crowned shape and stretching the piano’s strings to a higher pitch. And while the wooden soundboards produce a wonderful sound, they also react constantly to weather. To understand why, you must realize that the piano’s main acoustical structure, the soundboard, is made of wood (typically 3/8-inch thick Sitka spruce).
