Hi I came home to hear a drip when I walked past my a/c unit where the filter is .I opened it up see about 3 1/2 inches of pooling water in the bottom of the unit as well as wet carpet,I soaked it up thinking it would stop,turned it on again for a few turned it off I then saw a curtain of water drain down again an I'm worried I need a major repair... help please... can I fix?
