Kuala Lumpur heat and humidity keep bedroom and living-room air-conditioners running every night. Over four to six months, household dust combines with condensation to form thick algae jelly inside the drain pan and PVC condensate pipe, choking airflow and causing water to drip down painted walls onto beds, curtains or laminate floors.
At Repair KL, we operate on a strict honesty rule: we NEVER push unnecessary refrigerant gas top-ups during routine servicing. Split-unit air-conditioners are sealed loops; R32 and R410A refrigerant does not get consumed in normal operation unless a flare nut or coil has developed an actual leak. We check operating pressure with gauges as part of servicing and only recommend gas work if pressure is genuinely low, alongside checking the flare joints.
Choose between our RM99 basic service for regular 4-to-6-month upkeep, or our RM160 chemical wash when a unit has gone over a year without cleaning, smells musty, blows weak air at full fan speed, or ices up across the evaporator fins.
What is included
- Waterproof wrap-around wash bag so rinse water never splashes onto walls, curtains or mattresses.
- Cleaning of mesh filters, front fascia, swing louvres, drain pan and condensate drain pipe.
- Check of compressor running amps, supply-air temperature drop and refrigerant pressure.
- Wiping dry the indoor casing and surrounding floor area before completion.
- 30-day warranty against repeat water-dripping issues on units we service.
What is not included
- Car / automotive air-conditioning (we strictly service residential and light office building units).
- Refrigerant gas recharging, replacement capacitors, thermistors, fan motors or PCB boards.
- Dismantling/relocating units or running new concealed copper piping.
- Abseiling or skylift access where outdoor condensers are hung outside high-rise walls without a safe ledge.

Get a QuoteCommon problems we fix
Water dripping steadily down the wall from the indoor unit
Algae jelly has blocked the condensate drain outlet or rear trough; we flush the drain line clear and test with a full jug of water.
Weak airflow even when fan speed is set to maximum
Dust-caked squirrel-cage blower blades cannot throw air; dismantling and washing the blower wheel restores quiet, strong airflow.
Indoor unit blows room-temperature air without cooling
We check whether the outdoor compressor failed to start due to a blown capacitor, relay fault or genuine refrigerant leak at the flare nut.
Sour or damp smell during the first 10 minutes of running
Mould biofilm growing on damp evaporator fins causes musty odours; coil washing removes the buildup at its source.
Ice forming across indoor fins or timer light blinking error codes
Coil icing signals restricted airflow or low refrigerant pressure; we read error codes on Daikin, Panasonic, Midea, Acson and Mitsubishi units.
Outdoor condenser on condo ledge rattling loudly at night
Loose casing panels, hardened anti-vibration pads or choked condenser fins make outdoor units strain and rattle.
Preparing Your Room for a Clean, Fast Aircond Service
A standard clean takes 35 to 45 minutes per indoor unit, while a chemical wash takes 50 to 70 minutes per unit. Before our technician arrives, simply move laptops, books or pillows directly underneath the indoor unit to leave roughly one metre of clear floor space for a step ladder and catch bucket.
We only need access to your nearest bathroom tap and one wall socket to run our low-splash coil washer. Every indoor unit is shrouded in a waterproof catchment funnel that channels dirty wash water straight into a sealed bucket, keeping wallpaper, curtains and timber flooring dry.
Please note that we service residential and office building air-conditioners only, never car air-conditioning. Once reassembled, we run the unit with you for 10 minutes to verify crisp cold airflow and dry drain flow before collecting payment via cash, DuitNow QR or bank transfer.

Frequently asked questions
How often should home aircond units in KL be serviced?
Bedroom units running 7 to 9 hours nightly perform best with a basic service every 4 to 6 months to prevent drain jelly blockages and high electricity draw. Lightly used guest-room units can go 8 to 12 months.
Does a chemical wash corrode aluminium evaporator fins?
Not when performed properly with HVAC-formulated coil cleaner followed by a thorough fresh-water rinse. We never use harsh raw acid that eats away thin fins or leaves stinging fumes indoors.
Which aircond brands do your technicians service?
We service all residential inverter and non-inverter split units sold in Malaysia, including Daikin, Panasonic, Acson, Midea, Mitsubishi Electric, Sharp, York, Haier, Hisense and Samsung.
What if the unit drips water again a week after servicing?
Message us on WhatsApp right away. Under our 30-day workmanship warranty, our technician returns free of charge to re-check tray alignment and flush the condensate line again.
