So since both of the air handlers are installed in the ceiling, they are sitting in a huge tray with an emergency drain. Sunday, water was coming out of the big unit emergency drain.
Funny side story was that I bought those leak detector sirens that Gren mentioned. On my Sunday checklist was to place one in each drain pan, just hadnt make it that far down my list yet.
Anyway, I make sure the drain line is clear. It was. I open the unit up and make sure the drain line is clear from inside the unit. It was. So where the hell is the water coming from. I snoop and snoop.... and the damn drain pan under the coil is cracked so the water isnt even making it to the drain line. They are coming out this afternoon to replace it.
So here is the real question, obviously the actual air handler has had sitting water in it. While the repair man is up there replacing this drain pan, should something be sprayed in there? Lysol? Bleach? Bathtub mildew cleaner?
