Hello- I'm new here and need to ask a quick question. My wife and I are about to purchase a new home. It has never been lived in and we decided to put together a "make this right" list. I was looking around in the attic and noticed that the one of the air units has a 1" pvc pipe coming out of what looks to be the coil and it is blowing cold air. The pipe is comes out of the side of the unit near the bottom about 2 inches and then make a turn upwards about an inch. There is cold air pouring out of it. I'm no expert, but this doesn't sound right. Any thoughts/suggestions?
