When I noticed a water stain spreading across my living room ceiling, I traced it back to the air conditioner condensate line. The pipe had become clogged with algae and debris, causing the overflow to seep through the drywall, leaving a musty smell and bubbling paint. I had to cut out the damaged section, replace the insulation, and install a cleanout tee for easier maintenance. It was a messy job, but now the AC drains properly without any more ceiling leaks.
