An AC leaking water can be caused by several issues. Here's a quick guide:
• Check and clean the condensate drain line
• Ensure the drain pan isn't cracked or overflowing
• Verify the air filter isn't clogged, causing coil freezing
• Inspect for low refrigerant, which can lead to freezing
• Make sure the condensate pump is working properly
• Check if the unit is level to allow proper drainage
If these simple checks don't resolve the issue, it's best to call a professional. Persistent leaks can cause water damage and mold growth, so prompt attention is important.
