Lol, I didn't read the other answers because I'm sure they say run the A/C as much as possible with the windows tightly closed. I don't know who in their right mind would suggest turning of the air conditioner and using a dehumidifier instead. I would say max the air conditioner, also run a dehumidifier, large propeller fans and portable heaters. Heat lowers relative humidity given a volume of air, so the air becomes a better moisture sink. Propeller fans move alot of the air, moving the moist air away from the wet surfaces allowing dryer air to contact the wet surfaces. A dehumidifier is going to dehumidify and add heat to aid in moisture absorption. And an air conditioner is (especially in a tropical climate) a gigantic moisture sucking device that will literally pull pounds if water from the air every hour. It's a shame that the landlord and the "mold expert" are very uninformed about enthalpy. After all of this you should check the evaporator coil for any live mold and consider a coil mounted UV light. Being in a tropical climate your evaporator coil likely never has a chance to dry. And since mold spores are probably very present due to the rain forest, the evap is a breeding ground for mold and bacteria. Here in Canada we have short, hot, damp summers, with cold and dry winters. UV lights are not common but I can now understand why they exist.
