If you’re a seasonal homeowner or snowbird in South Florida, clogged AC drain lines can quickly turn into costly disasters, especially when you’re not there to notice.

One of the most common HVAC problems in humid areas like Boca Raton, Delray Beach, and Highland Beach is a blocked AC condensate line. Left unchecked, it can lead to AC shutdowns, mold growth, or even ceiling and floor damage.

Fortunately, it’s easy to prevent, and Absentee Home Watch can do it for you as part of our Home Watch Services for absentee homeowners.

What Causes Your AC Drain Line to Clog?AC drain line maintenance for absentee homeowners in South Florida

Your air conditioner removes moisture from the air and sends it through a small PVC drain pipe. Over time, this pipe can collect:

Algae and mold buildup
Dust and pet hair
Sludge from condensation
Outdoor debris or insect nests

When clogged, water can back up into the unit, trip the safety float switch, or even cause water damage to your home.
