Just had a Trane unit installed with air handler installed horizontally in the attic. There's no or VERY little condensed water flowing out of the unit. The foiled insulation on the inside bottom of the unit in soaked and water is starting to drip onto the over flow pan. I had the tech come out THREE times and the problem still persists. He check the drain for cloggs and proper pitch and it was ok. Does the handler have to be level (which it currently is)? I'm at my wits end!!! Does anyone have any Ideas???
