Why Air Conditioners Produce and Sometimes Leak Water
AC units remove moisture from the air as part of the cooling process, the evaporator coil gets cold enough that water vapour from the room air condenses on it, like condensation on a cold glass. This condensate is collected in a drain tray and flows out via a drain pipe. When the drain system fails, water overflows into the room, the most common form of AC water leak.
In Goa, the volume of condensate produced is much higher than in drier climates because the incoming air is so humid. A unit that drains adequately in a dry climate may overflow during Goa monsoon if the drain is partially blocked.
- Condensate production: 1–3 litres per hour depending on humidity and AC size
- Higher humidity means more condensate, monsoon Goa produces maximum drain load
- Any partial blockage in the drain chain becomes a full blockage under monsoon conditions
Blocked Drain: By Far the Most Common Cause
Algae, mould, dust, and debris gradually block the condensate drain pipe. The blockage usually occurs at the drain pan outlet, at bends in the pipe, or at the pipe exit point outdoors. The fix is straightforward: locate and clear the blockage.
- Check the outdoor pipe outlet first, often blocked by algae plug or debris
- Use a wet-dry vacuum at the indoor drain outlet to suck out the blockage from the inside
- Pour dilute bleach into the drain tray after clearing, kills algae that caused the blockage
- If blockage recurs within weeks, the drain pipe slope may be incorrect, professional correction needed
Other Causes of AC Water Leakage in Goa
A blocked drain is the first thing to check, but it is not the only cause. Low refrigerant, a dirty evaporator coil, or incorrect installation can all cause water to drip from the indoor unit in different ways.
- Low refrigerant: evaporator gets too cold, ice forms, then melts in a flood when AC stops, call technician
- Dirty evaporator coil: water cascades off the coil instead of dripping into the drain tray, coil cleaning needed
- Incorrect installation: indoor unit not sloped toward the drain, water collects and overflows at the wrong end
- Cracked drain tray: water bypasses the drain outlet, tray replacement needed
Fixing the Leak and Preventing Recurrence
Most AC water leaks in Goa can be prevented with basic pre-monsoon maintenance. Drain flushing is the single most effective step, it clears the accumulation that builds through the dry season before the high-condensate monsoon months arrive.
- Pre-monsoon drain flush: pour dilute bleach into the drain tray, let it run through the pipe
- Monthly: check the outdoor drain pipe outlet is clear during monsoon
- Annual professional service: technician inspects drain pan, pipe slope, and coil, catches developing issues
- If leakage recurs after clearing the drain, call Aermac to diagnose, may be refrigerant or coil issue

My AC leaks only during Goa monsoon, is this normal?
Not exactly normal, but very common. The monsoon greatly increases condensate volume, which overwhelms a partially blocked drain that was managing fine in dry conditions. The fix is to properly clear and flush the drain system before monsoon each year. Contact Aermac for a pre-monsoon drain service to prevent this recurring.
