Water Leak From HVAC outgoing pipe

There is condensation due to AC and there is pipe on my unit which goes outside. Please see attached picture.

Ist part of series of pipes are PVC and then there is copper pipe. I think it is corroded and there is green coloring as well which I think combination of copper, water and oxygen.

Is this normal? I had AC guy came yesterday and he said he has never seen anything like that. It was NOT leaking yesterday. Now water is every where.

I have shut down AC but water is still coming out. Is this normal and how long will it take to stop. Is there any thing I can do over weekend to stop leak?

My AC guy does not do this kind of work, who should I call, plumber? How can I stop this happening in the future?


PS: How do I rotate pictures. I asked in some earlier post but did not get any answer!

Most likely cause is the condensate drain is plugged up.
That copper line should have been cut out and replaced long ago with PVC.

That is one long, crazy routing for the drain. It looks like the drain line is not sloping downhill to the drain. Where the clamp is seems low then the pipe goes high to make room for the trap which exits low then the copper is going upwards. I would be tempted to replace it all and neaten up the routing and get all the piping sloping downhill toward the drain. And I would remove the copper and have PVC going all the way outside.

If you want to fix what you have I would start with the trap as they often clog but with your crazy long pipe with low spots the clog could be anywhere. You may have to cut it in several sections to be able to snake through it. After you have all the line clear you can glue it back together with couplings.

How do you replace copper which is in the wall. It must be lots of hours. I live on 2nd floor condo. It is concrete slab construction and there is no crawl space. I don't want to even think about amount of $$$s it will take.

When the pictures are large..... the attachment system tries to get as much of the pictures posted so it sometimes rotates them for best fit. You have to resize your pictures, go back to the attachment paper clip, delete the current pictures and then upload the resized ones. I usually pass thru every thread with pictures checking them.

What is directly on the other side of that unit and drain ?

You need to find out where the drain line runs. Since there is a closet behind.... it doesn't connect there. It looks to me like the A/C was added much later to the building. You may find your refrigerant lines and that drain line run downstairs thru a closet below. Maybe you can check into that.

It is kind of tricky situation. Air handler is in Kitchen closet and kitchen is front of building. Drain is going about 9 feet through wall to downstairs unit then another 10 feet again through the wall to outside of building to water the plants!

But refrigerant line goes down (not sure exactly where) and move backwards to rear of building where compressor is.

Luckily leak was in the right below air handler unit and there were no signs of water or wetness downstairs. It is repaired now.
