( but excellent suggestion ) In Phoenix, where every third house has a "swamp" cooler, nothing affects a piano more. Here we are very much aware of the effects of the cooler first, the monsoon season second. Depending on their use of 100% air conditioning, I recommend the cooler people to tune several weeks after they have shut the cooler off, and after the monsoon season has left. It impairs income, but makes for much more stable pianos. Thank you for the input. B. Simon Phoenix
