Question I have a trane vertical air handler with the coil at about a 60 degree angle. This system is about 20 years old.
Most of the condensation water is draining normal except some of is dripping from the evaporator coil into the intake air duct instead of running down the coil fins to the pan. Both sides of the evaporator unit are free of all debris and not clogged up.
I first noticed this yesterday when I discovered a puddle of water on the floor under the air handler.
Why all of a sudden does some of the condensation water decide to drip into the air intake duct off the coil instead of following the coil to the pan? If the coil was vertical instead of at an angle, this wouldn't be happening.
Thank you for your time.

Answer The fins are spaced to retain water. Your fins may look clean but have collected crud over the years & the crud breaks the surface tension of the water that holds the drop to the fins. You need a coil cleaner to spray on the coil to make them squeaky clean again.
