Why Is My AC Leaking Water Inside? — Causes & Fixes for Scarborough Homeowners
Causes of Indoor AC Water Leak
- Clogged condensate drain line — #1 cause. Algae, mould, and debris block the drain. Water backs up and overflows the drain pan. Fix: flush drain line with diluted bleach or compressed air. Annual maintenance prevents this.
- Frozen evaporator coil thawing — Melting ice overflows the pan. Root cause: low refrigerant or dirty coil.
- Cracked or rusted drain pan — Common on AC units 10+ years old. Replacement: $100–$200.
- Disconnected drain line — Vibration can loosen connections over time.
What to Do When AC Is Leaking Water Inside
- Turn off AC immediately to prevent further water damage and coil freezing
- Place towels or a bucket under the indoor unit
- Replace filter (blocked filter causes coil freezing)
