central ac, shooting water
i recently moved into a house with central ac. i never had central ac before. my question is: there is a copper tube which i beleive is comming from the the compressor, which is in the house, in a closet, its about 3/8" od, and stands upright next to the condensor (i think that is it the condensor?) outside the house. the end of the tube is blocked off with what looks to be wood puddy, why i dont know. the tube has a split in it, near the bottom, that looks like it burst from being frozen. the tube will release a spray of water about every 20 minutes of operation. is this normal, and why is the the tube sealed off? the ac seems to work very well!
