Do I need drain pan for A/C unit in closet?

Answer 1

It's smart insurance!

I don't know if you have a condensate pump, or if it drains on its own, but anything can happen. The impeller broke on my pump, it was running away - doing nothing. My wonderful builder or his sub-contractor tucked the overflow float wires into the wiring cabinet, but connected to nothing! Water all over the floor.

Drains can plug, tubing crimped, you get the idea.

Answer 2

yes,the moisture or density from the ac has to go somewhere,thats why when you see an ac in a window or anywhere for that matter,there is always water dripping from it.unless it has a drain or pan for it to go into.
