If your air conditioner is leaking water inside your home, it can be a frustrating and potentially damaging problem. Fortunately, many common causes of water leaks can be easily diagnosed and fixed with a few simple steps. In this comprehensive guide, we will explore the various reasons why your air conditioner may be leaking water inside and provide detailed instructions on how to fix the issue.
Causes of Air Conditioner Water Leaks
Before attempting to repair a water leak, it is essential to identify its source. Here are some of the most common causes of air conditioner water leaks:
- Clogged Drain Line: The drain line is responsible for draining condensation from the air conditioner. A clogged drain line can lead to water backing up and leaking inside the unit.
- Dirty Air Filter: A dirty air filter can restrict airflow, causing the evaporator coil to freeze. When the ice melts, it can leak water into the unit.
- Refrigerant Leak: A refrigerant leak can cause a drop in pressure, leading to ice formation on the evaporator coil and subsequent water leaks.
- Damaged Evaporator Coil: A damaged evaporator coil can allow water to leak through its surface.
- Loose Connections: Loose connections in the refrigerant lines or drain line can cause water to leak from the joints.
- Oversized Air Conditioner: An oversized air conditioner may not run long enough to remove all the moisture from the air, leading to condensation buildup and water leaks.
- Improper Installation: An air conditioner that was not properly installed may have misaligned drain lines or loose connections, causing water leaks.

Frequently Asked Questions
1. Why is my air conditioner leaking water even though I have a new filter?
Your air conditioner may still leak water even with a new filter if the drain line is clogged or the evaporator coil is damaged.
2. Can I use a bleach solution to clean the drain line?
Yes, you can use a bleach solution to clean the drain line. However, be sure to flush the line thoroughly with clean water afterward to prevent corrosion.
3. How do I know if my air conditioner is oversized?
An oversized air conditioner will typically run for short cycles and leave your home feeling humid. You can also use an energy calculator to determine the correct size for your space.
4. What are the signs of a refrigerant leak?
Signs of a refrigerant leak include a drop in cooling performance, hissing noises from the unit, and ice buildup on the evaporator coil.
5. Can I fix a refrigerant leak myself?
Attempting to repair a refrigerant leak yourself is not recommended. Refrigerant handling requires specialized equipment and knowledge. Contact a qualified HVAC technician for assistance.
