You switch on your aircon to escape Singapore’s relentless heat—then notice a puddle forming on your floor. Aircon Dripping Water isn’t just a nuisance; it can damage walls, carpets, and even your ceiling. With over ten years fixing aircon leaks for HDBs, condos, and offices at Vedha Aircon, here’s a technician’s guide to what’s behind that drip and how to stop it—fast, affordably, and with no fuss.
1. Clogged Condensate Drain Line
Problem: The condensate drain line carries condensation from your indoor coil out of the unit. Dust, mould, or algae can clog this PVC or copper pipe, causing water to back up and overflow the pan.
Signs:
- Water pooling near the indoor unit’s base
- Musty smell as stagnant water sits in the line
- Intermittent dripping that stops after sitting
Solution:
- DIY Clear: Carefully remove the drain line cap and use a wet‑dry vacuum on the exterior end.
- Professional Service: Vedha’s same‑day drain‑line flush uses compressed air and safe aircon cleaning agents to clear deep blockages .
- Prevention: Schedule quarterly maintenance to keep the line clear year‑round.
2. Damaged or Misaligned Drain Pan
Problem: The drain pan beneath the evaporator coil collects condensation. Cracks, corrosion, or misalignment will let water spill over.
Signs:
- Constant, heavy dripping regardless of humidity
- Visible rust or cracks on the pan lip
- Water damage or stains beneath the furnace
Solution:
- Inspect & Replace: Technicians can remove and examine the pan. Small cracks may be sealed; severely damaged pans get swapped out.
- Realign Unit: Ensuring the indoor unit is level prevents uneven overflow. Vedha’s technicians use precision tools to shim and secure your pan.
3. Frozen Evaporator Coil
Problem: When airflow is restricted or refrigerant is low, coils freeze. As they thaw, excess ice melts and floods the drip pan, causing leaks elsewhere.
Signs:
- Ice formation on copper lines or coils
- AC runs normally then suddenly drips as ice melts
- Hissing sound or frost visible on vent grills
Solution:
- Shut Down & Thaw: Turn off the AC and run the fan until ice clears.
- Restore Airflow: Replace or clean filters, and clear obstructions around vents.
- Check Refrigerant: A leak‑test and recharge may be needed. Vedha’s certified team pinpoints leaks and recharges to manufacturer specs.
4. Faulty Condensate Pump
Problem: In installations where gravity drainage isn’t possible—e.g., basement ceilings—the condensate pump pushes water out. If the pump fails, water backs up.
Signs:
- Pump has power (indicator light on) but no discharge
- Water drips near pump housing or reservoir
- Clicking or humming from a struggling pump
Solution:
- Clean & Test: Remove debris from the pump’s float switch and impeller.
- Replace Pump: If the motor or switch fails, Vedha offers affordable same‑day pump replacement.
- Add Redundancy: Install a secondary float switch to shut the system off before overflow.
5. Improper Installation or P‑Trap Issues
Problem: Drain piping without a proper P‑trap (U‑bend) can allow backflow or air locks that prevent water from exiting cleanly.
Signs:
- Gurgling sounds when AC turns on
- Water spurts back toward the unit after the cycle ends
- Insects or debris entering through an unsealed drain
Solution:
- Install/Repair P‑Trap: Vedha ensures a correctly sized P‑trap to maintain seal and prevent siphoning.
- Secure Connections: All drain joints are sealed with waterproof mastic and inspected for sagging.
6. Excessive Humidity & Over‑Cooling
Problem: Running the AC at very low setpoints in Singapore’s humid air generates more condensate than the drain system can handle, even if it’s clear.
Signs:
- Heavy dripping only on extremely hot, humid days
- AC cycles very frequently (short‑cycling)
- Drips begin shortly after start‑up and last minutes
Solution:
- Raise Thermostat: Set to 24–26°C to balance dehumidification and cooling.
- Add Dehumidifier: In high‑moisture spaces, a standalone dehumidifier reduces load on your AC.
- Upgrade Drain Line: For high‑end systems, Vedha can install a larger‑diameter condensate line to cope with peak loads.
7. Maintenance Neglect
Problem: Skipping regular servicing means filters, coils, drains, and pumps aren’t inspected—small issues compound into major leaks.
Signs:
- Recurring leaks that stop after a DIY flush
- Gradual increase in dripping frequency over months
- Rising electricity bills indicating inefficient operation
Solution:
- Routine Checks: Quarterly “aircon normal service” catches leaks before they start.
- Annual Overhaul: Deep chemical wash, coil cleaning, and full drain‑line flush in a single visit.
- AMC Plans: Vedha’s Annual Maintenance Contract guarantees priority visits and transparent pricing.
