When clients see an air conditioner leaking water, it can be frustrating and even alarming. A little condensation is normal, but when puddles start forming around the indoor unit or you notice your central AC unit dripping water nonstop, it’s a sign that something isn’t right. Let’s talk about why does AC leak water and when it’s time to call for professional ac repair.
Why Is My AC Leaking Water?
There are several reasons for a leak. Some are minor, and others require immediate attention. Here are the most common causes explained in simple terms:
1. Clogged Condensate Drain Line
The drain line’s job is to carry water away from the unit. Over time, dust, dirt, and even algae can block it. When that happens, the water has nowhere to go and backs up into your home. Clearing the line often solves the problem, but it should be done carefully to avoid damage.
2. Dirty Air Filter
When the air filter is clogged, airflow gets restricted. This causes the evaporator coil to freeze, and once it melts, you’ll notice a pool of water around your unit. Changing filters regularly can help avoid this issue.
3. Low Refrigerant Levels
Refrigerant keeps the coils cool. If it’s low, the pressure in the system drops, causing coils to freeze. When those coils thaw, water spills into places it shouldn’t. Low refrigerant usually means there’s a leak somewhere in the system, which requires professional repair.
4. Broken Drain Pan
The drain pan collects condensation, but if it’s cracked or rusted through, the water leaks out. This is common in older systems and may require a replacement pan or a full AC replacement.
5. Improper Installation
If the unit wasn’t installed with the correct slope, water won’t drain as it should. That’s why choosing trusted experts for AC installation is so important.
When Is a Central AC Unit Dripping Water Normal?
Sometimes a little water outside the unit is no cause for concern. Condensation happens naturally during cooling, especially on hot and humid days in Louisiana. But if you notice:
- Water pooling indoors near the air handler.
- Constant dripping outside even when the unit isn’t running.
- Stains on walls or ceilings near the AC.
- Musty odors that suggest mold growth.
Then it’s no longer normal. These signs mean your system needs inspection and likely repair.
Dangers of Ignoring an Air Conditioner Leaking Water
A small leak might not seem urgent, but it can snowball into larger problems. Here’s why addressing it quickly matters:
- Water Damage to Your Home – A steady drip can damage flooring, walls, and ceilings. Repairs for water damage are often more expensive than fixing the AC problem itself.
- Mold and Mildew Growth – Standing water creates the perfect environment for mold. This not only damages your home but can trigger allergies and breathing issues.
- Bigger AC Repairs – What starts as a simple clogged drain can lead to frozen coils, refrigerant issues, or even compressor failure if ignored. Calling for AC repair at the first sign of trouble saves money and stress.
Preventing AC Water Leaks
The best way to avoid a leak is through regular care. That’s where professional AC maintenance comes in. During a routine service, our technicians:
- Clean the coils so they don’t freeze and cause water buildup.
- Flush the condensate drain line to keep it clear.
- Replace dirty air filters that strain the system.
- Check refrigerant levels to prevent frozen coils and leaks.
Pro Tip: Don’t ignore your maintenance visits. Scheduling service twice a year—before summer and before winter—keeps your AC running smoothly and reduces the risk of leaks and breakdowns.

Frequently Asked Questions
1. Why is my AC leaking water inside the house?
This usually happens when the condensate line is blocked or the coil freezes due to airflow issues.
2. Can I run my AC if it’s leaking water?
It’s better not to. Running it could cause more damage or lead to mold. Turn it off and schedule AC repair.
3. How much does it cost to fix an AC water leak?
Minor fixes like clearing a drain line may cost less than $200. Bigger issues, such as refrigerant leaks or broken parts, will cost more.
4. Is it normal for my central AC unit to drip water outside?
Some dripping is normal outdoors during cooling. But if the puddle is constant or large, have it inspected.
5. Why does AC leak water after turning off?
This often means condensation is still draining after the system shuts down. If it’s excessive, it could point to a blocked drain line or broken pan.
