Having condensation near the AC's drain pipe is not unusual during warm weather. However, if you see more leaking than expected, that signals a problem with the AC. In addition, the leaking is often due to a damaged drain pan, clogged drain line, dirty filter, low refrigerant, or broken condensate pump. If you notice any heavy leaking, it is best to contact experts as soon as possible. A professional will have the proper equipment and knowledge to efficiently and quickly solve the issue.
