What to do when leaving
If you are taking off for the summer, as many people do, it is a good idea to leave all drawers and closets open. You can get a dehumidifier to run for a few hours a day or program your AC units to run for a few hours a day in Dry mode. If you have solar, I recommend having them run mid-day for 4 hours each, otherwise run them at night. Also, if you have someone that will do it, have them check on your place from time to time. The rain can often find its way into your home during rainy season.
