It can be unsettling to see Dripping Water from Air Conditioner or AC leak water inside your home. A little moisture from the air conditioning system is normal, but a steady leak of water, puddles, or dripping water from the AC unit indicates a bigger problem. In Peoria, AZ, where summers are hot and long, your AC works hard to cool the air and remove moisture from the air. If water is coming indoors or you see water dripping from your air conditioner, take action quickly to prevent further water damage and keep the system running safely.
How To Fix Dripping Water from Air Conditioner?
This guide explains common causes of water leaks from AC, how to troubleshoot at home, and when to call pros like Bridge Plumbing & HVAC for expert AC repair, cleaning, or installation.
Why Is My Air Conditioner Dripping Water?
Your air conditioner does more than cool the air. It also pulls moisture from the air. Warm air from your home passes over the cold evaporator coil, where moisture in the air condenses. That water drips into a drain pan, then flows through a drain line outside. When everything drains well, you never notice.
Water becomes a problem when something interrupts this process. A clogged drain line, dirty air filter, frozen evaporator coil, or poor installation can cause your AC to leak water. If water isn’t draining, it can leak water inside the home, creating risk of water damage and mold.
Most Common Reasons Your AC Is Dripping Water
Understanding common causes helps you decide if it’s simple maintenance like cleaning, or if professional ac repair is needed.
1. Clogged Condensate Drain Line
The most frequent ac leak cause is a clogged drain line. Dust, algae, and dirt buildup can stop water from draining. When the drain line blocks, excess water backs up and spills into your home.
Signs include:
• Water dripping near the indoor AC
• Musty smell
• Mold near the line
Ignoring clogged air drains can lead to water leakage issues, floor damage, and mold.
2. Frozen Evaporator Coils
When airflow is blocked, the evaporator coil can freeze. After thawing, the drain pan fills too fast, causing water leaking inside.
Causes:
• Dirty air filter
• Low refrigerant
• Blocked vents
Look for ice on AC coils, weak airflow, or water dripping after thawing.
3. Dirty Air Filter
A dirty air filter restricts airflow, making the evaporator coil too cold, forming ice. When it melts, AC water leaks happen.
Replace filters every 1 to 3 months to improve airflow, prevent water leakage, and protect indoor air quality.
4. Damaged or Rusted Drain Pan
Older air conditioning units often have metal pans that corrode. A cracked drain pan lets water escape, causing leaking water inside.
A technician can repair or replace the pan a simple repair.
5. Low Refrigerant Levels
Low refrigerant makes the evaporator coil cold enough for ice to form. When ice melts, leaks follow.
Other signs:
• Warm air
• Hissing sounds
• Higher bills
Because refrigerant handling requires certification, call for ac repair.
6. Poor Installation
If the unit leaking water is new, poor ac installations may be the cause. A unit not level or sized correctly may drip indoors. Incorrect installation can also make air to freeze or water flow the wrong direction.
Is Water Dripping from Your AC Dangerous?
Some water outside is normal, but water leaking from an air conditioner inside your home can cause:
• Mold
• Electrical hazards
• Damaged walls and flooring
Fast attention helps prevent further water damage.
Signs You Shouldn’t Ignore
Call a professional if you notice:
• Water leaking inside
• Frequent ac leaking water
• Ice on the ac unit
• Musty or burning smell
• Weak airflow
• High indoor humidity
These can signal blocked airflow, failing parts, or refrigerant leaks.
Quick Troubleshooting Steps You Can Try
Some issues are easy to check at home:
• Replace dirty air filter
• Look for clogged drain line
• Turn AC off if coils are frozen
• Clear items blocking vents
• Check thermostat setting
If ac is leaking water inside after trying these steps, a technician should inspect the system.
When to Call a Professional
Call an expert when:
• AC is leaking water continuously
• Water damage is visible
• AC keeps freezing
• You suspect low refrigerant
• System is older than 10 years
Professional help prevents larger issues, reduces risk of water leakage, and protects indoor air.
