Why Climate Control?

Temperature & Humidity and Your Piano

A Dampp-Chaser system can prevent damage and maintain tuning stability in your piano!

Use this chart to see if your piano is exhibiting symptoms of instability or damage.

	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.

All wood shrinks and swells with humidity changes - even your piano

	Sticking Drawers In the summertime when humidity levels in the air are higher, you may notice that some of your drawers stick. This is because the wood absorbs moisture from the air and swells.
	Sticking Doors You may have a door that works perfectly in dry seasons, but sticks when the humidity goes up.
	Sticking Keys Just as doors and drawers become tight with high humidity and loose in dry air, the keys of your piano may stick down when struck in times of high humidity. When the environment surrounding your piano is dry the keys may seems to rattle when played.
	Sluggish Action As you play your piano, you will notice how responsive the keys are to your touch. The way the keys cause the wood hammers to strike the piano strings is part of thousands of interconnected wooden parts called the piano action. With high moisture levels in the piano action, the action is sluggish, and the keys seem non-responsive to your touch.
	Loose Furniture Joints Glued wooden joints become loose and wobbly when the air in your home becomes dryer from winter heating or from a change to dry weather
