Is water leaking from your AC unit creating puddles on your floor? You’re not alone. AC water leakage is one of the most common air conditioning problems Kenyan homeowners face, especially during our hot seasons. This comprehensive repair guide will help you understand why water is leaking from your AC and how to fix it.
Why Is Water Leaking from Your AC?
When water leaking from your AC appears, it’s usually a sign that something is blocking the normal drainage process. Your air conditioner produces condensation as it cools your home, and this water needs to drain properly. When it doesn’t, you’ll notice water leaking from your AC unit.
Common Causes of Water Leaking from Your AC
1. Clogged Condensate Drain Line
The most frequent cause of water leaking from your AC is a blocked drain line. Dust, algae, and debris accumulate over time, preventing water from flowing out properly.
DIY Fix: Use a wet/dry vacuum to suction out the clog from the drain line. This simple solution stops water leaking from your AC in many cases.
Professional Cost: KES 2,000 – KES 4,000 for drain line cleaning and flushing.
2. Dirty Air Filter
A clogged air filter restricts airflow over the evaporator coil, causing it to freeze. When the ice melts, you’ll see water leaking from your AC.
DIY Fix: Replace your air filter every 1-2 months. Filters cost between KES 500 – KES 1,500 depending on your AC model.
Professional Cost: KES 1,500 – KES 3,000 if you hire a technician for filter replacement and system check.
3. Frozen Evaporator Coil
Low refrigerant levels or poor airflow cause the evaporator coil to freeze. When it thaws, excessive water leaking from your AC occurs.
Professional Cost: KES 8,000 – KES 15,000 for refrigerant recharge and coil inspection. This requires a licensed HVAC technician.
4. Damaged or Disconnected Drain Pan
Older AC units (10+ years) often have rusted or cracked drain pans, causing water leaking from your AC to appear around the indoor unit.
Professional Cost: KES 3,500 – KES 7,000 for drain pan replacement, including labor.
5. Broken Condensate Pump
If your AC unit is installed in a basement or below ground level, a malfunctioning condensate pump can cause water leaking from your AC.
Professional Cost: KES 8,000 – KES 18,000 for condensate pump replacement.
6. Low Refrigerant Levels
Refrigerant leaks reduce pressure in your AC system, leading to frozen coils and eventually water leaking from your AC.
Professional Cost: KES 10,000 – KES 25,000 depending on the leak location and refrigerant type needed.
Step-by-Step Guide to Fix Water Leaking from Your AC
Step 1: Turn Off Your AC
Immediately switch off your air conditioner to prevent water damage and electrical hazards when you notice water leaking from your AC.
Step 2: Check the Air Filter
Remove and inspect your air filter. If it’s dirty or clogged, replace it. This solves water leaking from your AC in about 30% of cases.
Step 3: Inspect the Drain Line
Locate the condensate drain line (usually a PVC pipe near your outdoor unit). Check for visible clogs or standing water.
Step 4: Clear the Drain Line
Pour a mixture of one cup white vinegar and one cup warm water down the drain line. Wait 30 minutes, then flush with plain water. This prevents algae buildup that causes water leaking from your AC.
Step 5: Check the Drain Pan
Look under your indoor unit for the drain pan. If you see cracks, rust, or standing water, you’ll need professional replacement to stop water leaking from your AC.
Step 6: Examine the Evaporator Coil
If you see ice on the coil, turn off your AC and let it thaw completely (2-3 hours). Ice formation indicates a serious issue causing water leaking from your AC.
