A/C Unit Drain Overflow Cleanup in San Marcos, California
Possible Causes of A/C Drain Overflows
One common reason for A/C drain overflow issues is a clogged condensate drain line. Over time, dirt, algae, and debris can build up within the drain line, causing blockages that prevent proper drainage. When water cannot flow freely, it can back up and overflow into your property, leading to water damage and potential mold growth.
Another frequent cause is a cracked or damaged drain pan. The drain pan collects condensate from your air conditioning system. If it becomes cracked or rusted, it may leak or overflow, especially during periods of high humidity or heavy cooling demand. Additionally, improper installation or aging equipment can contribute to drain line failures and overflow problems.
