AC Leaking Water Inside Your Home

Water around your air handler usually points to a clogged condensate drain line, a full or cracked drain pan, a frozen coil that is thawing, or a disconnected line. Our high humidity keeps drain lines full of algae year-round, so this is one of the most frequent problems we solve. We clear the blockage, flush the line, and check the pan and float switch so it does not come back next week.

Signs You Need This Service

• Water pooling around the indoor air handler
• Ceiling or wall stains under a closet or attic unit
• The unit shuts off on its own (float safety switch tripping)
• Musty smell from standing water in the drain pan

Common Causes

• A clogged condensate drain line, the most common cause here, where algae and mud back water up into the pan and out onto the floor.
• A full, cracked, or rusted-through drain pan that can no longer hold or channel the condensate the system produces.
• A frozen evaporator coil that is thawing, dumping more water than the drain can handle all at once.
• A disconnected or improperly sloped drain line that lets water escape before it reaches the drain.
• A failed condensate pump on systems that rely on one to move water up and out.

How We Handle It

1. Locate the source: drain line, pan, coil, or connection
2. Clear and flush the condensate line and treat for algae
3. Test the float switch and inspect the drain pan
4. Confirm the leak is stopped and drainage flows freely

Why This Happens in South Florida

Water leaks are one of our most frequent calls in South Florida for one reason: humidity. Our air holds so much moisture that AC systems pull gallons of water out of it every day, and the warm, damp condensate lines are a perfect breeding ground for the algae and mold that clog them. During the summer wet season the problem peaks, and a line that was fine in March can back up and flood a closet by July. Clearing and treating the full line, not just poking the visible end, is what keeps it from returning.
