I thought I remember being told that water should drip (condensation) from the bottom pvc that comes out of the house but it should never drip from the top pvc. I thought he told me that if it dripped from the top it meant the "pan" was full and needed to be emptied. I was told recently that it's normal for them to both drip some because of the humidity right now. I'm not sure which answer is correct and if there is something I need to do about it now. |

When the forced air unit is in the attic sometimes the condensation is drained into a normal interior drain and a second, outside drain is used for overflow. The overflow drain is in a visible place so you know that the main drain isn't working and you can fix it. In fact I had this very problem a few weeks ago. If you remember being told it should never drip from the upper drain, it sounds to me like it could be a secondary overflow drain. In that case it would be worth getting it checked out. |

if by "top" PVC you mean the PVC tube coming out of your house that corresponds to your upstairs AC unit, then yes, this is normal. all air conditioners pull water out of the air as they cool, and that water has to go somewhere. however, there is no definite answer we can give you because there are so many ways the condensate drain could be configured. in your old house, you might have had 2 condensate drains on one air conditioner. the second drain could have been installed so that if the pan was about to overflow, it went down the second drain instead. so the second drain serves as a signal that the first one is clogged. in short, the only way to be sure is to have someone qualified trace the drain lines and figure out how these units are configured. |
