Our ac condensation line runs to the drain in one of our upstairs bathrooms. The sink must have been clogged and the condensation came up thru the sink and overflowed onto the floor. Unfortunately, it's in a bathroom that rarely gets used unless we have guests staying with us and we keep that door closed so my 3 year old won't go in there. My 8 year old daughter mentioned that the floor was wet outside of the bathroom one day and thought maybe she or her little brother had spilled something there. We told her to just dry it up with towels. She didn't mention how big of an area it was that was wet or how many towels she needed to dry it up at the time. The upstairs is just bedrooms for the kids, a guest room and a playroom so my husband and I sometimes go days without going up there. The next day, my 20 year old son came over and went upstairs to get something out of his old room and made a comment about the floor being wet. My husband went upstairs and we found that the water had soaked the carpet for about 6 to 8 feet outside of the bathroom as well as the carpet in the bathroom too. Fortunately, that bathroom is over the garage so there was only a small water stain on the garage ceiling, but nothing inside the house. We have a bissell proheat steam cleaner so we just used that to soak up all the water that we could and then we put lots of fans blowing all over the area for a couple of days. There was staining on the carpet that we had to use the steam cleaner to clean once it was dry, but there was no lasting smell or anything like that even though this had obviously been going on for a couple of days at least. If you have a steam cleaner with good suction or even a wet/dry shop vac, you might try sucking up the water yourself before spending the money to have it done professionally. Of course, there is always a chance it will smell musty or moldy and a professional may be able to avoid that. Fortunately, we were able to do it ourselves. I will warn you, if you don't get a reputable company, a lot of time the ones trying to get you to spend more money will tell you that you need to pull up the carpet and pad and replace them even when that's not really necessary so be careful if you go that route. Good luck!
