AC leaking water indoors is one of the more alarming discoveries a Tamarac or Sunrise homeowner can make, especially with how much moisture South Florida’s humidity pulls out of the air on a daily basis. Before you imagine the worst, an AC leaking water usually has a simple, fixable cause. Here’s how to spot it and what to do next.

3 Quick Checks for AC Leaking Water
- Look at the drain pan. Standing water in the pan under your indoor unit is one of the clearest signs of a blocked line.
- Check your air filter. A severely clogged filter can cause the coil to freeze, which then leaks water as it thaws.
- Check the outdoor drain line exit. If water isn’t dripping from the PVC pipe outside during operation, it may be backed up.
Common Causes of AC Leaking Water
A clogged condensate drain line is the most frequent reason behind this issue. As your system pulls moisture from South Florida’s humid air, that condensation has to drain somewhere, and algae or mold buildup inside the line can block that path entirely.
A frozen evaporator coil is another common cause, restricted airflow from a dirty filter causes ice to build up, and as it melts, more water arrives than the drain pan and line were designed to handle at once. A cracked or rusted drain pan, more common in older systems, can also let water escape directly instead of channeling it outside.
What Happens If You Ignore It
This rarely stays contained to just the unit itself. Left unaddressed, it can damage ceilings, walls, and flooring, and standing moisture creates conditions where mold can begin growing within days. According to the EPA’s guidance on indoor moisture control, addressing water intrusion quickly is one of the most effective ways to prevent mold growth in a home.
Common Questions
Should I turn off my AC if it’s leaking water?
Yes, turning off your system when you notice AC leaking water is a good first step. This stops more water from accumulating while you wait for a technician and reduces the risk of additional damage to your home.
Can I clear the drain line myself?
Some homeowners have success flushing the line with a wet/dry vacuum at the outdoor exit point. If it has already caused visible damage, it’s worth having a technician inspect the full system rather than just clearing the clog.
A little prevention goes a long way here, and it’s far easier to catch AC leaking water early than to deal with ceiling or flooring damage after the fact.
