The drain pancatches water inside the unit. Look for cracks or rust. A damaged pan can cause leaks. Replace it if broken or bent.
Examine the window seal. It stops air and water from getting inside. Gaps or cracks let water drip indoors. Use weather stripping or sealant to fix it.
The unit’s tiltmatters. It should lean slightly outside to drain water. A flat or inward tilt traps water, causing leaks. Adjust the angle using shims or blocks.
Quick Fixes For Water Leaks
