What It Means When Your Air Conditioner Is Dripping Water
If you’ve noticed your air conditioner dripping water, you’re not alone. This is a common issue for homeowners, especially in hot and humid areas like Houston and surrounding communities. While a little condensation is normal, active dripping or pooling water is usually a sign that something’s wrong with your AC system.
At Bellaire Air Conditioning, we specialize in diagnosing and fixing AC issues like leaks, poor airflow, and refrigerant problems. In this post, we’ll cover the most likely reasons your air conditioner is leaking water and what you can do about it.
1. Clogged or Dirty AC Drain Line
One of the most common causes of water dripping from an air conditioner is a clogged condensate drain line. Over time, dirt, dust, and algae can build up and block the line, preventing proper drainage. When the water can’t flow out, it backs up into the system and begins to drip from your unit.
This is especially common in humid areas like River Oaks and West University Place, where excess moisture increases the likelihood of buildup.
Solution: Schedule an AC maintenance service to have your drain line inspected and cleared.
2. Frozen Evaporator Coils
If your system is leaking and your home isn’t cooling well, frozen evaporator coils might be to blame. When airflow is restricted—often due to a dirty filter or blocked vent—moisture on the coils can freeze. When it melts, it can overflow the drip pan and cause leaks.
If you’re experiencing this issue in Katy or Bellaire, it’s important to address it promptly to avoid further damage.
Solution: Replace your filter and book a cooling repair to inspect your system’s airflow and refrigerant levels.
3. Damaged or Rusted Drain Pan
Air conditioners have a drain pan that collects water and channels it out through the drain line. If the pan is rusted or cracked, water may drip out of your indoor unit.
This issue is common in older units, especially in homes around Sugar Land or Cinco Ranch, where ACs might not have been replaced recently.
Solution: If your AC is aging, it may be time for a new air conditioning system installation, or at the very least, drain pan replacement.
4. Low Refrigerant Levels
Low refrigerant can reduce pressure in your AC system, causing evaporator coils to freeze. As with dirty filters, once the ice melts, the excess water can overflow the pan and leak onto your floor.
If your AC is blowing warm air and dripping water in Houston or West University Place, this may be your problem.
Solution: Have your system checked for refrigerant leaks and recharged if needed. We offer expert refrigerant diagnosis and AC repair to keep your system running efficiently.
5. Poor Installation or Improper Slope
When an AC unit isn’t properly leveled during installation, water may not flow correctly into the drain line, leading to drips or indoor leaks. This is often seen in DIY or rushed installations.
Solution: Schedule a professional inspection to assess the slope and drainage system. At Bellaire Air Conditioning, we ensure every system we install is set up for long-term performance.

FAQs
How do I stop my air conditioner from dripping water?
Start by checking your air filter. A dirty filter can block airflow and cause the evaporator coils to freeze and leak when they thaw. Next, inspect the condensate drain line for clogs. If the drain line is blocked, water will back up and start to drip. You’ll also want to check the drain pan for cracks or rust. For long-term prevention, schedule routine AC maintenance to keep all parts clean and functioning properly.
Can I still use my AC if it’s leaking water?
Technically, yes—but it’s not recommended. Continuing to use an AC that’s dripping water can lead to mold growth, water damage, and further system breakdown. If the leak is due to a clogged drain line or frozen coil, running the system will only make the issue worse. It’s best to turn it off and address the root cause to avoid costly repairs.
How to fix water dripping from split AC indoor unit?
If your split AC unit is dripping water indoors, the problem could be a blocked drain pipe, dirty filter, frozen coil, or an issue with the condensate pump. First, clean or replace the air filter. Then, inspect the drain line and ensure it’s not obstructed. If you’re still seeing leaks, the unit may need a professional inspection to check for internal blockages or refrigerant issues.
Is AC leaking water an emergency?
It depends on the severity. A slow drip may not seem urgent but can lead to hidden damage over time. On the other hand, a large or continuous leak can quickly cause ceiling or wall damage, especially in multi-story homes. If your unit is leaking near electrical components or soaking indoor areas, it’s better to treat it as an urgent repair.
Should I turn off my AC unit if it is leaking?
Yes. Turning off your air conditioner when it’s leaking water can prevent further damage and help avoid safety hazards. It also allows the system to thaw if frozen coils are involved. Once it’s off, it’s easier for a technician to assess the cause and recommend the right fix.
