I have water coming from my carpet in the middle of my bedroom , it did this the a week ago and stopped, and now its leaking again. It started after my A/C unit was repaired. What could cause this?

Apparently the run off hose for the a/c got somehow misdirected. Contact the a/c repairman and have him come and find out where it is now directed.

Which floor? What kind of floor under carpet? I your house a built on a slab?

Is this s slab house or a basement/crawl space? Could be a plugged condensate drain and it's running under the sill plate.

Im with the folks above, waiting to hear what kind of floor it is under the carpet
