Is Your Aircond Leaking Water in Selangor? Here’s the REAL Fix (Before You Call Us)

Seeing water dripping from your air conditioner in Selangor? That puddle on your floor isn’t just annoying – it’s a warning sign that needs immediate attention. As Selangor’s trusted AC Service specialists since 2015, we’ve fixed thousands of leaking AC units across Petaling Jaya, Shah Alam, and Klang Valley homes.

Quick Answer: Most aircond leaks in Malaysia come from clogged drain pipes, dirty filters, or frozen coils. You can try cleaning the drain pipe yourself, but if water keeps coming after 24 hours or you see ice on the coils, you need professional help immediately to prevent wall damage and mould growth.

Why Your Aircond Leaks Water (Selangor Edition)

First, don’t panic! Water leakage is actually your AC working correctly in one way – it’s removing humidity from your air. The problem happens when that water can’t escape properly. Here are the top 3 reasons we see in Selangor homes:

1. Clogged Drain Pipe (The #1 Culprit – 70% of Cases)

Your AC pulls moisture from humid Selangor air (we average 80% humidity!). This water should flow through a plastic pipe to outside. When that pipe gets clogged with algae, dirt, or insect nests (common in Malaysian housing areas), the water backs up and leaks indoors.

2. Dirty Air Filter

A clogged filter restricts airflow, causing the evaporator coil to freeze up. When that ice melts (often during our afternoon thunderstorms), it creates more water than the drain can handle. This happens especially during rainy season when filters get dirty faster.

3. Installation Problems

If your unit wasn’t leveled properly during installation (even slightly!), water can’t flow toward the drain. We’ve fixed countless units in new Shah Alam developments where rushed installation caused this issue.

The REAL Fix: Step-by-Step (What We Tell Our Own Family)

⚠️ Safety First: Always turn OFF your aircond at the main switch before checking anything. Wait 30 minutes for any ice to melt.

Step 1: Check & Clean the Drain Pipe (10-Minute DIY)

1. Locate the white PVC pipe coming from your indoor unit to outside
2. Pour 1 cup of warm water mixed with 2 tablespoons of white vinegar down the pipe
3. Listen for gurgling – that means the clog is clearing
4. If water backs up immediately, the clog is serious

Pro Tip from Our Technicians: Do this monthly during rainy season to prevent clogs. Malaysian humidity makes pipes clog 3x faster than in drier climates.

Step 2: Inspect & Change Your Filter

1. Remove your filter (check your manual if unsure)
2. Hold it up to light – if you can’t see through it, it’s too dirty
3. Wash with gentle soap and water if it’s washable type
4. Let it dry COMPLETELY before reinstalling (damp filters grow mould!)

Step 3: Check for Ice Buildup

1. After turning the unit off for 30 minutes, remove the front cover
2. Look at the silver coils – see any ice or frost?
3. If yes, you likely have a refrigerant issue (not a DIY fix!)

When Your DIY Fix Isn’t Enough – Time to Call ACFix

Stop here if you notice ANY of these red flags:

✅ Water continues leaking after 24 hours
✅ You see ice on the coils (even small amounts)
✅ The leak is yellow/brown (sign of serious algae growth)
✅ Your wall or ceiling has water stains
✅ You smell musty odours when the AC runs

These signs mean you have a deeper issue that requires professional equipment and expertise. Continuing to run a leaking AC can cause:

• Structural damage to your Selangor home (repair costs: RM2,000+)
• Mould growth behind walls (health hazard!)
• Electrical shorts and fire risk
• Compressor failure (replacement: RM1,500-RM4,000)

Why Quick Action Matters in Selangor’s Climate

Our tropical weather creates perfect conditions for two problems when your AC leaks:

1. Mould Growth: Within 48 hours of a leak, mould spores start growing. This isn’t just about bad smells – it’s a health risk, especially for children and elderly family members. If you’re noticing musty smells already, read our guide on how to stop mould and bad smells from your AC unit.
2. Electrical Damage: Malaysia’s high humidity + water leakage = increased risk of short circuits. We’ve seen leaking ACs trip entire house electrical systems in Petaling Jaya homes.

What Our Certified Technicians Do (That You Can’t DIY)

When you call us for professional AC Repair, our Selangor-based technicians:

1. Use industrial-grade vacuum pumps to completely clear drain lines
2. Apply anti-algae treatment that prevents clogs for 6+ months
3. Check refrigerant levels with precision gauges (improper levels cause freezing)
4. Test drain pan integrity (cracked pans need replacement)
5. Inspect installation alignment and correct if needed
6. Provide 90-day warranty on all leak repairs

Prevention: Your Monthly 5-Minute Checklist

Save this simple routine to avoid future leaks:

☑️ Weekly: Check for water droplets around indoor unit
☑️ Monthly: Clean/replace filters, pour vinegar water down drain pipe
☑️ Every 3 Months: Schedule professional maintenance (especially before rainy season)
☑️ Annually: Get full system inspection from certified technicians

Regular maintenance isn’t just about preventing leaks – it also keeps your aircond cooling efficiently. If you’ve noticed your unit struggling to cool along with leaking, you might have multiple issues. Learn about common cooling problems and fixes in Malaysia.

“Should I Just Get a New Unit?”

We get this question often. As honest technicians, here’s our advice:

Repair if:

• Your unit is under 5 years old
• The leak is from drain pipe only
• Repair cost is under RM400
• Cooling performance is still good

Consider replacement if:

• Unit is over 8 years old AND needs major repair
• You’re spending >RM600/year on repairs
• Energy bills keep increasing
• Multiple problems exist (leaking + not cooling + noisy)

Important Energy Consideration: If your AC is over 7 years old and frequently needs repairs, you might save more money long-term with a new energy-efficient model. Modern inverter ACs can use 30-50% less electricity. For a detailed comparison of costs and savings, check this guide on inverter vs non-inverter ACs in Malaysia.
