Coming from a cool part of California, I wasn't prepared for the humidity readings I kept seeing in my room at the Crystal City Hyatt. All these years I had read that AC took moisture out of the air and here I was reading 78% on my brand new Damppchaser humidistat. Finally one tech told me that in many large buildings such as the hotel or university buildings they are using a new type of airconditioning that actually puts moisture back into the rooms. That probably doesn't explain your customer's problem though. Moisture is a constant problem for us here on the coast and under the giant Redwoods. Next week I have to go back on a Steinway grand I rebuilt about ten years ago; customer complains it is too heavy. I asked her about the damppchaser, she says "Oh, we don't want to bother with that." It's in an unheated, non-insulated summer cabin in the woods :-( Diane ----Original Message Follows---- From: staytuned@idirect.com (John Lillico, RPT) Reply-To: pianotech@ptg.org To: pianotech@ptg.org Subject: Re: Air Conditioning Date: Sun, 13 Aug 2000 01:15:06 -0400 >I think Larry Messerly is both right and wrong.

I asked a heating engineer about this. He said that most central air units are too large for the area they cool. When temperature drops too quickly the units shut off leaving RH at these high levels. I long for a good snowfall.
