Originally had concern about installing a mini split A/C vent over my grand. The location of the grand opens up to a 800 square feet area and the piano has the piano saver , undercover and string cover installed. The A/C will only get limited use on and off 2-3 months out of the year and ambient outdoor climate averages 70F with 60-70% humidity, but some summer days can bump up to high 80's, 80%-90% humidity. I live along the coast, about 3miles so I don't really want to open up the windows that much when the temp rises and it can get a little stuffy which is why I want to put in A/C. My house is insulated with double pain insulated glass and insulated cinderblock construction.
I was thinking about a full piano cover but not really attractive but if necessary could use it when the A/C is on. Anyone have any thoughts from experience?
Heres a photo , the vent will be directly above the curtain rod centered.
