In Orlando, the most common cause is a clogged condensate drain line. Your air conditioner removes significant humidity from the air, and that moisture drains through a PVC line. Algae, dust, and debris can block it, causing water to back up into the drain pan and overflow. Other causes include a cracked drain pan, disconnected drain line, frozen evaporator coil, or improper unit installation. High humidity levels in Orlando make systems work harder, increasing condensate volume. If you see recurring leaks, the issue is rarely just “normal condensation.” A proper inspection should confirm drainage slope, pan condition, float switch function, and moisture migration into surrounding materials.
