Florida house from 2005, Trane unit. Handler is in the garage mounted to the roof. The system is sweating and producing a lot of water. Air filter is new, I have flushed the system with a house from the outside, and have added bleach water to the drip pan. It is dripping water outside. I did notice that there is a screw or two missing from the bottom of the unit. and also the overflow sensor is sucking in air, not sure if that is normal. Any ideas or is it normal with the florida high heat to sweat like that?
