We currently have a humidistat which has lowered our electric bills but, here’s my concern. We have several wooden, stringed, musical instruments. When the humidistat was installed we were told that during the summer months, we should keep it set to 65% humidity. The humidistat will keep the humidity from going over 65%, but it does nothing to keep the temperature from getting too high.

Yes, A/C can still turn on, but only when the humidity has gone over the 65% threshold.

I’m concerned that if the inside temperature goes to 90 or 100 degrees (even if the humidity is 65%), it could damage our instruments. That high temp will dry out the wood and will result in cracks and weakened glue. So far we’ve been hauling our instruments back and forth with us but the idea of leaving them here and flying between Michigan and Florida is becoming more attractive.

I read a report from someone here in Kings Point. He said his humidity has NEVER gotten over 65% when the temperature was under 85. (He runs a Nest system where he can see the temp and the humidity.) He suggested a setting of 85 on the A/C. That will keep the humidity lower than 65%.

We will probably not use the humidistat this year and see how our electric bills are.
