AC Water Leakage: Causes & Fixes
Updated January 2026 · 2 min read
Quick Answer
AC water leakage indoors is usually a blocked drain pipe, dirty filters causing coil freeze-thaw, or an incorrect installation slope. Turn off the AC, check the drain outlet, and book plumbing-aware AC service if dripping continues.
Key Takeaways
- Blocked drain pipes are the #1 cause in humid Mumbai.
- Frozen coils that melt can overflow the drain tray.
- Reinstall or re-slope the drain hose if water pools near the indoor unit.
Water dripping from a wall-mounted AC is common during heavy use in Mumbai and Thane. The drain line carries condensate outside; algae and dust block it quickly in coastal humidity. You may notice stains on the wall below the indoor unit or pooling on the floor tray.
Start by checking whether the drain hose is kinked or disconnected at the outdoor end. If the indoor coil is iced over, switch off the AC for 30 minutes — melting ice can overflow a partially blocked drain. Do not poke sharp objects into the drain pipe.
A ProFixer technician flushes the drain with safe pressure, verifies tray level, and inspects the installation slope. If the leak started after a recent service visit, the drain may have been repositioned incorrectly — a quick correction often fixes it without parts.
