Two AC items

[Mike and Jane Spalding]

Clyde,

A teacher that I tune for has two pianos; one vertical and one grand, both of them "modest" instruments.  Both are equipped with Dampp-Chasers, and have been reasonably stable, although a hot humid turn in the weather will mess them up, temporarily, until the humidity drops again.  2 weeks ago they installed central air, and she tells me both pianos have gone south.  It will be interesting to observe over the next year whether the C/A will, in the long haul, help or hurt the turning stability.  I suspect our Milwaukee weather is not very different from yours in PA.

regards,

Mike Spalding, RPT
