why is my ac leaking water

An air conditioner leaks water most commonly due to a clogged condensate drain line, which prevents proper drainage and causes water to overflow inside. Other frequent causes include a damaged or rusted drain pan, dirty air filters leading to frozen evaporator coils, low refrigerant levels causing ice formation, and a broken condensate pump. Maintenance tasks like cleaning the drain line, changing air filters regularly, and checking refrigerant levels help prevent leaks. If the drain pan is damaged or rusted, replacement is needed. In some setups, a condensate pump malfunction can also cause leaking water inside the home. These issues cause water to accumulate and leak within or around the AC unit rather than draining away properly outside.
