I live in humid hot Mexico. I have 4 BAir mini splits. The master bedroom runs for about 8 hours every night. I always run it on Dry mode to save electricity and it makes the room comfortable. This is the only unit that gets this much use. It is also the only unit that continues to have a dripping problem. I have had technicians out to clear the drain tube, reposition the tube, service the unit and troubleshoot the problem multiple times. It continues to happen with this unit only. I clean my filters monthly and have regular service done on the units. Why does this continue to happen? I have read that Dry mode causes more condensation on the coil. Could it be that there is just too much water for the drain tube to handle?
