Well, first of all, have a qualified repair technician examine the instrument. If I am traveling I check my phone mail regularly. Following are a few examples of some interesting pieces we restored recently. Place a humidity gauge on or near your piano. If it is much higher or lower you need a Damp Chaser Humidity Control Device.
All pianos suffer terribly from unstable humidity conditions.
A small investment in the humidity control now will save hundreds or thousands of dollars in repairs or restoration in the coming years. Your piano should be tuned at least twice yearly if you live in a climate where the relative humidity and temperatures vary significantly. This has the effect of causing soundboard problems over a period of time, necessitating expensive repairs. Two things to keep in mind. First, it is absolutely true that you tend to get what you pay for.
