Why Is My AC Leaking Water?

1. Clogged Drain Line — Most Common Cause ($75–$200)

In South Florida’s humidity, your AC removes enormous amounts of moisture from the air. All that water drains through the condensate drain line. When algae, mold, or debris clog this line, water backs up and overflows from the drain pan. This is the #1 cause of AC water leaks — and the easiest fix. Prime Air flushes and clears the line same-day.

2. Cracked or Rusted Drain Pan ($150–$400)

Your AC’s secondary drain pan catches overflow water. In older South Florida systems, this pan rusts through or cracks — water that should be caught and drained spills onto your ceiling or floor instead. Replacement is straightforward.

3. Frozen Evaporator Coil — Melting Ice ($150–$500+)

When your evaporator coil freezes and then thaws, excess water overwhelms the drain system and overflows. The freeze itself is caused by low refrigerant, restricted airflow, or dirty coils. The water leak is a symptom — the freeze is the problem. Prime Air diagnoses and fixes both.

4. Improper Installation or Disconnected Drain Line ($100–$300)

A drain line that’s sagging, disconnected, or improperly sloped won’t drain — water backs up and leaks. Common after DIY work or unprofessional installations.

What to Do Right Now If Your AC Is Leaking

1. Turn off the AC immediately — running it will continue to produce water and worsen the damage
2. Place towels or a bucket under the leak to contain water
3. Don’t let it sit — in South Florida’s heat and humidity, mold can start growing within 24 hours on wet drywall and flooring
4. Call Prime Air — (561) 855-0659 for same-day drain line service
