Air Conditioning - Fast runoff drip

I'm clueless about ACs.There is a hose on the eave of my house where the ac runoff drips out.It is a steady drip lately,almost a stream.Is this normal or is something wrong?Shouldn't it be a SLOW drip? :confused:

I would get up there and check it out right now. like for code here. The drain of the AC runs out some where. Then there is a pan under the whole unit up there and its drain has to run outside so it is over a door window or sidewalk. So you will see it if the unit overflows and goes into the pan. So check it out ,also is the filter clean.

What filter? the air filter in the return air vent?

Yes the air filter . did you look and see just what you have up there?????

I cleaned my air filter this morning.I went up and looked just now and the pan isn't full,but there is a fast drip coming out of the pvc drain into the pan.

Check and make sure that the drain line is clear. You can use a shop vac to suck and blow in it. Is there any ice on the copper lines?? The big one should be cold and wet the small one warm. All the duct work up there ok?? Can you be haveing a very high humidity there now?

Knight4God, Any updates? Not sure what area of Texas you're in, but Dallas has been very humid and rainy for the past week. Even so, you shouldn't have water comming out of this pipe at all. Something's clogged.

What do you mean I should have no water coming out of that pipe?This pvc pipe is the only pipe that drains into my overflow pan. :confused:

The key word here is "overflow". There shouldn't be any water in the overflow _pan_ either. There should be a drain line that is plumbed directly into the drip pan, which is a part of the coil unit. Look for another PVC pipe that connects directly to the air handler or furnace. It probably connects next to the pipe that goes down to the overflow pan. You may not be able to get to the drip pan and will have to take the pipe apart to clean it out.

Ed described what a normal setup would be - primary drain from drip pan connects somewhere in the house to a drain (bathroom sink drain in my house) or goes outside (not normal in Dallas area). Then an overflow tray or pan is placed under the unit with it's own drain that goes outside over a window or door. The integrated drip pan on the furnace or air handler usually has a secondary drain slightly higher than the primary. Most of the time a pvc pipe is connected to the secondary drain and directed into the overflow tray or pan in case the primary drain clogs up.

Hope this helps
