🔴 Fix My Aircon Problem
System acting up? Not cooling properly? Making noise? Leaking water?
If basic cleaning didn't solve it, there's likely a deeper issue that needs proper diagnosis.
Common scenarios:
- Not cold → Often gas leaks, coil damage, or blower failure
- Water leaking → Usually drainage angles or insulation problems
- Strange noises → Typically motor wear or alignment issues
- Keeps shutting off → Protection sensors or control faults
What we do:
- Diagnose the actual root cause
- Explain findings clearly before proceeding
- Fix only what's needed
- Ensure the problem stays solved
🟢 Keep My Aircon Healthy
System running well? Let's keep it that way.
Preventive care means systematic assessment - not just surface cleaning.
What proper maintenance includes:
- System performance check
- Drainage testing
- Coil condition assessment
- Early problem detection before failures occur
- System report and recommendation after each visit
Recommended schedule: Every 4-6 months
This approach catches small issues before they become expensive problems.
🛠️ System Installation
New space? Renovation? Replacing a failed unit?
Most early system failures come from poor planning and installation shortcuts. We install with long-term performance in mind.
What proper installation includes:
- Load calculation for right-sized equipment
- Optimal placement for efficiency and maintenance access
- Professional trunking and secure mounting
- Proper refrigerant line sizing and insulation
- Correct electrical connections and drainage slopes
- Full system testing and commissioning
We don't just install equipment - we engineer solutions that work reliably for years.
"Just had my aircon serviced and by far the best and easiest guys to deal with for aircon servicing. Booking was quick. The guys who came over were really polite and clearly knew their stuff."

🔧 Our Team at Work
⚠️ Why Surface Fixes Don't Last
Many issues seem simple — but have deeper causes:
"Just needs gas top-up"
Gas doesn't vanish — there's always a leak that needs sealing
"Just needs cleaning"
If cleaning worked, the problem wouldn't return after weeks
"Just replace this part"
Without finding why it failed, you'll need another replacement soon
Signs You Need Proper Assessment:
Weak cooling
Often gas leaks, coil damage, or blower issues — not just dust
Low gas
Gas doesn't "run out" — if it's low, something's leaking
Strange sounds/smells
Usually motor, alignment, or drainage issues — not wear and tear
Leaking after cleaning
Drainage angles or insulation problems — not dirt
Blinking/shutting down
Logic errors, sensor faults, or PCB issues
Cold first, then warm
Gas loss, control issues, or internal blockage
Why These "Fixes" Keep Failing:
"Cleaned monthly, still not cold"
Spotless coils can't fix low gas or damaged blowers
"Chemical wash, water still leaking"
Poor drainage angles won't fix themselves
"Coils cleaned, noise remains"
Motor problems aren't dirt-related
"Top-up done, cooling dropped again"
The leak is still there, just temporarily filled
We don't treat surface symptoms. We diagnose the actual fault and fix it properly — so it stays fixed.
💡 The Truth About Gas Top-Ups
Why Gas Doesn't "Run Out"
Many customers assume a gas top-up is routine maintenance. But in a properly working aircon system, refrigerant doesn't get used up.
Aircon systems are sealed, closed-loop circuits. The gas circulates between the indoor and outdoor units to transfer heat — not to be consumed.
If your system is low on gas, it means there's a leak.
Not a usage issue. Not evaporation. A fault.
Why Blind Top-Ups Are Risky:
Compressor strain → Reduced lifespan, overheating, early failure
Pressure imbalance → Cooling issues, part mismatch, short cycling
Temporary cooling → Fault returns within days or weeks
Repeat breakdowns → More visits, more cost, deeper damage
Without a proper check, you're not fixing the system — you're masking the fault.
📖 How Your Aircon Actually Works
The Simple Truth About Cooling
Your aircon doesn't create cold air — it removes heat from your room and dumps it outside. Think of it like a heat pump working in reverse.
The 4-Step Process:
① Heat Absorption
The indoor coil (evaporator) absorbs heat from your room air as refrigerant gas flows through it.
② Heat Transport
The compressor pressurizes the hot gas and pushes it to the outdoor unit through copper pipes.
③ Heat Rejection
The outdoor coil (condenser) releases the heat into outside air, turning the gas back into liquid.
④ Cycle Reset
The liquid refrigerant flows back indoors, expands, and the cycle repeats.
Why Each Component Matters
Compressor = The Heart
Pumps refrigerant through the system. If it fails, nothing works.
Coils = The Lungs
Indoor coil absorbs heat. Outdoor coil releases heat. Block either one, cooling drops.
Refrigerant = The Blood
Carries heat from inside to outside. Leak anywhere, system fails.
Blower = The Circulation
Moves air over the coils. Weak blower = weak cooling, even with perfect coils.
Controls = The Brain
Sensors and PCB coordinate everything. Wrong signals = wrong performance.
⚠️ When Things Go Wrong
How Problems Spread Through the System
Everything is connected. A fault in one area stresses the others:
Dirty coil → Compressor works harder → Higher pressure → Earlier failure
Low gas → Coil freezes → Blower strain → Multiple breakdowns
Blocked drainage → Water damage → Electrical shorts → System failure
Weak blower → Poor airflow → Coil icing → Compressor overload
The Bottom Line: Your aircon is a precision system, not a simple appliance. Every component affects the other.
🔧 Common Problems & Solutions
The same symptoms can have completely different causes. Here's what we actually find when we investigate properly:
Not Cold After Cleaning
- Often gas leaks, coil damage, or blower issues
- System pressure well below recommended range
- Compressor startup behaviour may be normal, but cooling circuit failed
- Surface cleaning can't fix internal mechanical faults
Water Leaking from Indoor Unit
- Clogged drain line with algae or bio-growth
- Overflowing coil tray from improper tilt
- Dirty evaporator coil pushing dust into drain system
- Coil icing and melt overwhelming drainage
Strange Noises (Rattling, Buzzing, Grinding)
- Loose panel or front cover vibrating
- Unbalanced blower wheel from dust buildup
- Worn fan bearings causing grinding during spin
- Compressor hum without cooling = start capacitor failure
Unit Keeps Shutting Down
- Faulty thermistor misreading room temperature
- Relay or PCB fault causing power cutoffs
- Overheat protection from system strain
- Low gas triggering automatic shutdown
Blinking Lights or Error Codes
- Sensor fault (thermistor, coil sensor, tray sensor)
- Communication failure between indoor/outdoor units
- Drainage error from full tray or triggered sensor
- PCB logic fault or overcurrent protection
Gas Keeps Dropping After Top-Ups
- Micro leak in coil joints or connections
- Damaged flare joint from vibration stress
- Corroded copper line in older installations
- Previous overcharging causing compressor strain
If your problem isn't listed here, or if you've tried the "obvious" fix and it didn't work — that's exactly when proper diagnosis matters most.
