Hello, my air handler, which is located in a closet above the hot water heater in Florida with lots of humidity, is leaking water down the sides. I had the coils cleaned and the drain is not clogged and it seems that water is coming off the coils hitting the sides and forming puddles on the frame which holds the filter and then leaking on top of the hot water heater. I have had 3 different companies out and no one can help. Can you help me, PLEASE??

High blower speed could be stripping the water off the coil blowing it back into the air causing this problem. Lower blower speed one setting and give it a try.

Can you tell me how to lower the blower speed? What about splash guards? Thanks!

What about splash guards

Never heard of them.

There is a wiring diagram on the inside of the blower door. Follow the wiring to change speeds.
