Incidentally, staying on a beach island last 3 summers, and this summer the AC isn’t working right, only “cooling” about 1C. Set system to de-humidify instead, and air to room is 5C-7C lower temp than air at return. (As measured by a laser temp sensor.) Note that ambient humidity is above 80% so there’s plenty dehumidifying available.
