Did You Know?
1. While it may seem like a cause for concern, a window AC unit spitting out water is actually a sign that it’s working properly. This process, known as condensation, is a result of the unit cooling warm and humid air, causing the moisture to collect and be expelled through a drain.
2. One reason why your window AC may be spitting out excessive water could be due to a clogged drain pipe. Over time, dust, debris, and algae can accumulate in the drain, obstructing the water from flowing freely. Regular maintenance and cleaning of the drain pipe can prevent this issue.
3. The angle at which a window AC unit is installed can affect its water expulsion. If the unit is not level or inclined slightly towards the outside, it can cause water to collect and eventually spill out. Ensuring that your window AC is properly leveled can help avoid any water leakage.
4. In certain weather conditions, such as high humidity or extremely hot temperatures, window AC units tend to produce more condensation. This can lead to a higher volume of water being expelled. So, the amount of water being spit out can be influenced by the climate you live in.
5. Some window AC units come equipped with a feature called a “slinger ring.” This ring is designed to aid in the removal of excess water by using centrifugal force. As the fan inside the unit spins, it throws the water collected off the condenser coils onto the evaporator coils. From there, the collected water helps in cooling the coils, enhancing the unit’s efficiency.
Evaporator Coils And Moisture Collection
Air conditioners are designed to cool down the air in a room by collecting moisture on their evaporator coils. During the cooling process, warm air enters the unit and passes over the evaporator coils. As the air cools down, the moisture in the air condenses on the cold coils, similar to how water droplets form on a cold drink on a hot summer day.
The moisture collected on the evaporator coils should drip off into the condensate drain system, where it is safely carried away. However, there are instances when water from the evaporator coils does not properly drain, leading to leaks and potential damage to the AC unit.
Dripping Into The Condensate Drain System
The proper functioning of the condensate drain system is crucial to prevent water leaks from your window AC unit. This system, usually consisting of a drain line and a drain pan, is responsible for collecting and directing the water away from the unit.
The condensate drain system should allow water to flow freely and prevent it from backing up into the unit.
The water collected on the evaporator coils is supposed to drip into the drain pan, and from there, it flows through the drain line to a proper drain.
However, if the drain line becomes clogged or damaged, water may start to leak from your AC unit. It is important to regularly inspect the drain line and ensure that it is clear of any obstructions or debris.

Common Causes: Clogged Drain And Damaged Pan
One of the common causes of AC leaks is a clogged condensate drain. Dust, dirt, and debris can accumulate in the drain line over time, obstructing the flow of water. This can cause the water to back up and overflow, resulting in leaks from your window AC unit. Regular maintenance, such as cleaning the drain line, can help prevent this issue.
Another potential cause of leaks is a damaged drain pan. The drain pan is located beneath the evaporator coils and is designed to catch the water dripping from them. Inspect the drain pan for cracks or other damage regularly. If there are any signs of damage, it is important to replace the drain pan to prevent water leakage.
To prevent AC leaks:
- Clean the condensate drain line regularly to avoid clogs
- Inspect the drain pan for cracks or damage on a regular basis
- Promptly replace a damaged drain pan to prevent water leakage
Remember to properly maintain your AC unit to avoid potential leaks and other issues
Clogged Drainage System From Dust And Debris
Besides the clogged condensate drain line, other parts of the drainage system can also become clogged with dust, dirt, and debris. These particles can accumulate inside the AC unit, leading to a restricted flow of water and potential leaks. Regularly cleaning the system and removing any debris can help prevent clogs and keep your AC unit running smoothly.
- Clogged condensate drain line is not the only concern
- Dust, dirt, and debris can clog other parts of the drainage system as well
- Accumulation of particles inside the AC unit can lead to restricted water flow and leaks
- Regular system cleaning is necessary to prevent clogs and ensure smooth operation
Cracks And Damage In Drain Pan
The drain pan plays a critical role in preventing water leaks. While it is designed to withstand constant exposure to water, it can still develop cracks or other forms of damage over time.
Inspect the drain pan regularly for any signs of deterioration. If you notice any cracks or damage, it is important to replace the pan to prevent water from leaking out of your window AC unit.
Air Filter And Pressure Drop
A dirty air filter can cause a drop in airflow, leading to several issues, including freezing of the evaporator coils and water leakage. An air filter clogged with dust and debris restricts the amount of air that can pass through the AC unit. As a result, the pressure inside the unit drops, causing the temperature to drop excessively. This can result in ice forming on the evaporator coils, which eventually melts and contributes to water leakage.
Regularly cleaning or replacing the air filter can help maintain proper airflow and prevent freezing and water leakage. It is recommended to follow the manufacturer’s guidelines on filter maintenance and replacement intervals to ensure the optimal performance of your window AC unit.
It is important to understand the various reasons why your window AC unit may be spitting out water. From moisture collection on the evaporator coils to issues with the condensate drain system, several factors can contribute to water leaks. Regular maintenance, such as cleaning the condensate drain line and inspecting the drain pan, can help prevent and mitigate potential damage. Additionally, keeping the air filter clean and free of debris can help maintain proper airflow and prevent pressure drops that can lead to water leakage.
If you encounter persistent water leaks or other AC issues, it is best to seek the expertise of an HVAC technician to ensure proper repairs and a functioning air conditioning system.

Frequently Asked Questions
Why is my window AC blowing out water?
One possible reason your window AC is blowing out water is due to a clogged or blocked condensation drain. The condensation drain is responsible for draining the excess moisture from the unit, but if it becomes obstructed by debris or mold, the water can accumulate and eventually overflow. This blockage can lead to water being expelled from the AC, causing leakage.
Is it normal for an AC to spit out water?
It is not normal for an AC to spit out water unless there is an issue with either a clogged drain pipe or an improperly tilted window air conditioner. A clogged drain pipe can lead to water accumulation, causing the AC to expel the excess moisture. Similarly, if a window AC unit is not tilted correctly, the water condensation may not flow properly towards the drain pan, resulting in water being expelled from the unit. Regular maintenance and ensuring proper installation can prevent this occurrence.
Why is my AC spitting?
When your AC unit is spitting, it could be due to a clogged drain. The accumulation of dirt, mold, or algae in the drain can prevent proper drainage of condensate. Without a functioning drain, water can leak from the unit and affect its performance, resulting in the spitting behavior of the AC. Regular maintenance and cleaning of the drain can help prevent this issue and ensure optimal functioning of your AC system.
What are some possible causes for a window AC unit spitting out water?
One possible cause for a window AC unit spitting out water is a clogged or dirty air filter. When the air filter is dirty, it restricts the airflow and causes the evaporator coil to freeze up. When the unit is turned off, the ice thaws and results in excess water being expelled from the unit. Regularly cleaning or replacing the air filter can help prevent this issue.
