    16 Common Aircon Faults We Diagnose & Fix On-Site

    Our certified HVAC field technicians diagnose and resolve all cooling, electrical, gas leakage, and circuit failures on-site using genuine manufacturer OEM replacement parts:

    01
    Air Conditioner Blowing Warm or Room-Temperature Air (Not Cold)
    Root Technical Cause: Depleted refrigerant gas from micro-leaks, failed outdoor compressor start capacitor, jammed 4-way reversing valve, or choked outdoor condenser fins.
    |Our Solution: Refrigerant pressure diagnostic, electronic leak detection, dual-run capacitor replacement, and precision R32 / R410A gas top-up.
    02
    Indoor Unit Leaking Water or Dripping onto Furniture & Floor
    Root Technical Cause: Accumulated bacterial jelly and dust sludge blocking the condensate drain pipe, cracked drain pan, or poorly insulated copper piping causing condensation sweating.
    Our Solution: High-pressure nitrogen / water flush of drain line, anti-bacterial chemical sanitization, and heavy-duty Armaflex pipe insulation re-wrapping.
    03
    Outdoor Compressor Unit Not Starting / Loud Humming but No Fan

    Root Technical Cause: Burnt start/run capacitor, corroded outdoor magnetic contactor switch, or overheated compressor thermal overload protector.
    Our Solution: OEM heavy-duty capacitor replacement, contactor relay swap, and electrical operating current (running amp) calibration.

    04
    Blinking Timer / Operation LED Light & Diagnostic Error Code

    Root Technical Cause: Inverter communication signal breakdown between indoor and outdoor boards, faulty evaporator coil thermistor, or indoor fan motor RPM error.
    Our Solution: On-board fault code retrieval, NTC thermistor resistance testing, PCB signal diagnosis, and OEM sensor replacement.

    05
    Refrigerant Gas Leak (Low R32 / R410A / R22 Pressure)

    Root Technical Cause: Vibration cracking at copper flare nut joints, corroded evaporator U-bends, or worn service Schrader valve cores.
    Our Solution: Electronic halogen leak sniff test, copper flare joint re-flaring and brazing, nitrogen pressure hold test, vacuum evacuation, and exact factory gram gas recharge.

    06
    Heavy Ice & Snow-Like Frost Buildup on Indoor Evaporator Coils
    Root Technical Cause: Severe airflow restriction from choked air filters/evaporator coil, or low refrigerant level causing sub-zero boiling temperatures inside the coil.
    Our Solution: Deep chemical overhaul, blower wheel wash, gas pressure equalization, and expansion valve inspection.
    07
    Very Weak Airflow from Blower Fan (Even on Turbo / High Speed)

    Root Technical Cause: Cross-flow blower wheel heavily choked with thick fuzzy dust and mold biofilm, or failing brushless DC indoor fan motor.
    Our Solution: Dismantling and high-pressure chemical wash of rotary blower wheel, and DC fan motor bearing lubrication/replacement.

    08
    Foul Musty, Sour, or Chemical Odor Discharging from Vents

    Root Technical Cause: Black mold, fungal colonies, and mildew multiplying inside the damp indoor cooling coil fins and standing water in the drain tray.
    Our Solution: Anti-microbial alkaline chemical foam treatment, high-pressure coil rinse, drain tray disinfection, and deodorizing filter refresh.

    09
    Loud Squeaking, Rattling, or Vibrating Noise from Indoor Unit

    Root Technical Cause: Worn rubber cross-flow fan bearing bushing, out-of-balance blower wheel blades, or loose motorized swing louver stepper motor gears.
    Our Solution: Quiet silicone sleeve fan bearing replacement, blower re-balancing, and swing flap stepper motor alignment.

    10
    Air Conditioner Turns On and Shuts Off Automatically After A Few Minutes
    Root Technical Cause: Compressor high-pressure thermal cut-out tripping due to dirty outdoor condenser, faulty ambient sensor, or unstable voltage supply.
    Our Solution: Outdoor condenser chemical hydro-wash, thermal sensor replacement, and power supply voltage stabilization.
    11
    Outdoor Fan Spinning Normally but Compressor Dead Silent
    Root Technical Cause: Defective compressor thermal overload relay, open-circuit compressor internal winding, or blown inverter IPM board module.
    Our Solution: Compressor winding resistance test, overload protector swap, or inverter IPM board electronic repair.
    12
    Aircon Tripping House Main Circuit Breaker (ELCB / DB Box) Instantly
    Root Technical Cause: Short-circuited compressor motor stator winding, grounded fan motor, or moisture-corroded outdoor terminal wire block.
    Our Solution: Megger high-voltage insulation breakdown test, terminal rewiring, and grounded component safety replacement.
    13
    Remote Control Not Responding / Indoor Display Screen Inactive
    Root Technical Cause: Burnt sub-PCB infrared receiver sensor eye, corroded wire harness, or blown auxiliary power fuse on the main motherboard.
    Our Solution: Infrared receiver board replacement, circuit fuse replacement, and signal verification with universal tester.
    14
    Inverter PCB Motherboard Failure (Burnt Components / Surge Damage)
    Root Technical Cause: High voltage lightning surges, insect/gecko short-circuits across high-voltage traces, or burnt IGBT power switching transistors.
    Our Solution: Micro-soldering component-level board repair, IGBT transistor replacement, conformal protective coating, and surge protector installation.
    15
    Water Gurgling Noise & Stagnant Overflow from Aircon Drain
    Root Technical Cause: Negative pressure siphon effect or negative slope dip in condensate drain pipe causing airlock and water backup.
    Our Solution: Drain pipe slope re-gradient alignment, installation of anti-siphon trap, and vacuum clearance.
    16
    Ceiling Cassette / Commercial Unit Water Overflowing & Sensor Alarm
    Our Solution: Submersible drain lift pump replacement, float safety switch testing, and complete internal basin chemical sanitization.

    Frequently Asked Questions

    Why is my air conditioner blowing normal air instead of cold air?

    This is typically caused by low refrigerant gas pressure due to a micro-leak, a defective outdoor capacitor preventing the compressor from starting, or choked outdoor condenser fins. Our technicians carry diagnostic gauges and genuine OEM parts to resolve this on-site within 45 minutes.

    Water leaks occur when the internal condensation drain line is clogged with dust and bacterial algae slime, causing condensation to back up and overflow the drain tray. We perform a high-pressure line flush and chemical sanitization to eliminate clogs permanently.

    Our on-site inspection and diagnostic fee is a flat RM60 across all areas in KL and Selangor. If you decide to proceed with the repair work or chemical overhaul, this RM60 fee is 100%  Waived

    Normal servicing cleans surface filters and drain trays. A chemical overhaul involves completely dismantling the front casing, deep-cleaning the evaporator coil with specialized biodegradable chemical cleanser, washing the internal rotary blower wheel, and flushing the drainage line to restore maximum cooling performance and indoor air purity.

    We issue a formal 30-Day Written Warranty covering all installed genuine OEM replacement parts and technician workmanship for complete peace of mind.

    We accept Cash and Instant Online Banking / DuitNow QR Transfer upon job completion and after you have personally verified the sub-16°C cold airflow test.
