When I took the panel off, I found a couple of wires have what I think is dried mold on it, but I'm not sure. Does anybody know what else it could be? These wires are above the coil. Whatever it is...

    Can anyone tell me what this is?? It's in our office building and we don't know what it controls. Not sure if it's the thermostat or since it's next to the water cooler/dispenser it might control that, we just don't know. If anyone can shed any light on this answer it would be greatly...

    I have a relatively small room; approximately 14 x 13. (Or round it up to 15 x 15 as I don't remember for sure).

    We have no basement, but a lower level that allows entry from the garage. That lower level houses the furnace, A/C and a floor drain in the foundation. This year, the first time the A/C turned on, the drain backed up into the room. I assumed it had just been clogged with dust and debris from...
