The Piano Doctor

	Your piano goes out of tune when the humidity in the environment surrounding the piano changes. The humidity levels in your home environment are controlled to some extent by the temperature. Generally, an air conditioner will remove some summer humidity, but the drop in humidity, when winter dryness sets in, presents a significant moisture change which will put your piano out of tune.
The Dampp-Chaser Climate Control System maintains your piano at an average 42% relative humidity as recommended by major piano manufacturers. When your piano soundboard is kept at a constant moisture level, shrinking and swelling are minimized.
