AC Leaking Water Inside? 4 Tampa Causes
Water dripping from your air handler, ceiling stains near a closet, or a puddle on the garage floor where your AC lives — these are all variations of the same problem, and in Tampa it’s almost always solvable the same day. Here’s what’s causing it and how to fix it. Home Therapist: CAC1819196.
Quick Answer
An AC leaking water inside in Tampa is one of 4 things, ranked by likelihood: clogged condensate drain line (80% of cases, especially July-September), rusted drain pan (older systems), frozen evaporator coil from a dirty filter, or frozen coil from low refrigerant leak. DIY: turn off AC, find the PVC condensate pipe near the outside unit, check for clog. Most Tampa AC drain repairs run $279 (drain flush, drain line small repair). Drain pan replacement: $399-$699. Call (813) 343-2212.
4 Reasons Your AC Is Leaking
1. Clogged Condensate Drain Line (80%)
Symptom: Water dripping from air handler, overflow switch tripped (AC shuts off), wet drywall near air handler, musty smell.
Likelihood in Tampa: Extremely common in Tampa. Humidity drives massive condensation, and algae/mold clogs the drain line fast.
DIY: locate the white PVC pipe exiting the air handler, run it outside. Shop-vac the outside end to suck out the clog. Pour 1 cup white vinegar down the inside cleanout cap monthly. Professional drain line flush: $279.
2. Cracked or Rusted Drain Pan
Symptom: Water drips even when drain line is clear. Rust on the pan visible. Continuous small drip under air handler.
Likelihood in Tampa: Common on systems 10+ years old. Tampa humidity accelerates pan corrosion.
Primary pan replacement: $699 (vertical) or $799 (horizontal). Secondary metal pan install: $399. Replacing an entire air handler may be more cost-effective on systems 12+ years old.
3. Frozen Coil from Dirty Filter
Symptom: Ice visible on copper lines, water dripping AFTER AC has been off for an hour, AC struggles to cool.
Likelihood in Tampa: Common. Restricted airflow → coil freezes → when it thaws, water overflows the pan.
Turn AC OFF, replace filter ($89 professional replacement or DIY), run fan only 2-3 hours to thaw. If it freezes again, move to cause #4.
4. Frozen Coil from Refrigerant Leak
Symptom: Same as #3 but persists after filter change. AC runs constantly. Unit hissing. Higher bills.
Likelihood in Tampa: Common on Tampa systems 8+ years. Salt air + copper corrosion.
Licensed tech required. UV dye injection $449, leak repair $399, refrigerant recharge $95/lb (R-410A). Total typically $399-$599 for coil-side leaks, more for compressor-side.
What to Do Right Now
- Turn off AC immediately to stop water damage.
- Place towels/buckets under the drip. Move any valuables.
- Go outside to the condensate drain line exit (usually white PVC near the outdoor unit). Use a shop-vac to suction out the clog.
- Check the air filter. Replace if dirty.
- If water continues after steps 3-4, call (813) 343-2212. Likely pan issue or refrigerant problem.

Frequently Asked Questions
Why is water dripping from my AC in Tampa?
80% of the time: clogged condensate drain line. Tampa humidity produces gallons of condensation daily; algae blocks the drain. Try the shop-vac fix first, then professional flush ($279).
How do I clear a clogged AC drain line myself?
Find the white PVC pipe exiting your outdoor unit. Attach shop-vac to the end and run for 5 minutes. Should pull clog free. Monthly: pour 1 cup distilled white vinegar into the inside cleanout cap to prevent algae.
Will water damage my drywall if AC leaks?
Fast. Tampa humidity accelerates drywall saturation. Mold starts within 48 hours. Shut off AC and address the leak same-day. Small drywall repairs are cheap; full ceiling replacement is not.
How much to fix AC water leak?
Simple drain clog: $279 (drain flush). Drain line replacement: $699. Primary pan replacement: $699-$799. Float switch install (prevents future overflow): $279. Refrigerant leak repair: $399+.
Do I need a new air handler if drain pan is rusted?
Not necessarily. Pan replacement alone is $699-$799. But if your system is 12+ years and the coil is also showing rust, replacing the whole air handler may make more sense (saves duplicate labor).
Why does my AC only leak in summer?
Tampa humidity peaks June-September. Your AC pulls 3-5 gallons of condensate per day during peak. If the drain can’t keep up (partially clogged), you see leaks only in summer when volume is highest.
Is AC water leak covered by home warranty?
Usually yes for the AC repair itself (drain cleaning, pan replacement). Usually NO for the resulting drywall/flooring damage. Check your policy. Document everything for claims.
How often should I clean the AC drain line?
Monthly vinegar flush (DIY, 2 minutes). Annual professional drain line flush ($279) as part of a Home Therapy Plan tune-up. Tampa humidity demands more frequent care than northern climates.
Can I use bleach in my AC drain line?
We don’t recommend it. Bleach corrodes metal drain pans and can damage newer AC components. Use distilled white vinegar instead — kills algae, won’t corrode.
What's causing water to drip from vents?
Either ductwork condensation (poorly insulated supply ducts in hot attic) or coil overflow reaching ducts. Both need a pro — duct insulation wrap $99/ft for exposed attic runs.
