A unit that has stopped cooling, will not start or drips onto the floor needs the fault found before anything is replaced. We test first, name the part that failed, then repair it.
Your aircond runs, the fan turns, and the room sits at the same temperature it was an hour ago. Or it will not start at all, and the breaker drops the moment you press the button on the remote.
A unit left like that keeps drawing current while it cools nothing, so the bill climbs through a month you spent uncomfortable. A slow refrigerant leak also starves the compressor of oil, and the compressor is the most expensive part in the outdoor unit.
We repair wall-mounted splits, ceiling cassettes and the outdoor condensers that serve them, in homes and business premises across Kuala Lumpur and Selangor. Call +60178570744 with the make and model from the sticker inside the front cover.
How a repair visit runs
One complaint has several possible causes, so the visit starts with testing. A room that will not cool can come from a coil packed with dust, a tired capacitor or a leak in the refrigerant circuit. It can also be a control board that has stopped switching the compressor. Each needs a different repair, and only one of them is expensive.
Our technician works through them in cost order and tells you which one failed. You hear the part name, what it does and what the repair involves before any work starts. Where the unit is fifteen years old and the compressor has gone, we say so instead of quoting a repair that will not hold.
Faults we repair
Ten of the repairs we do most across Kuala Lumpur and Selangor, and what sits behind each one.
An outdoor unit that hums for a second and falls silent has usually lost its start capacitor, not the compressor most people fear. We measure the capacitance against the rating printed on the can and fit a matched replacement.
A breaker that trips the moment the aircond starts is interrupting a fault current. A shorted compressor winding, a swollen capacitor and water across the terminal block each cause it. We meter every circuit before the unit goes back on.
Gas does not evaporate. Cooling that faded slowly means refrigerant escaped somewhere, usually at a flare joint or a corroded bend in the evaporator. We pressurise the system with nitrogen, find the leak, repair the joint and charge to the weight on the nameplate.
An indoor unit that lights up but blows nothing has a seized blower motor or a failed motor capacitor. We turn the wheel by hand, read the winding resistance and replace whichever part measures open.
A unit that runs one mode only, flashes a code or answers nothing has a fault on the indoor control board. We read the stored code and test the sensors first. A board is the expensive part and often the innocent one.
A room or coil thermistor that has drifted sends the board a temperature that is not there. The board then shuts the compressor down early. We check the sensor resistance against the manufacturer table and replace the one that reads wrong.
Dust and slime build inside the drain line over a year of use until the pan overflows at the front of the casing. We flush the line, clean the pan and reset the fall on the pipe so the condensate runs away instead of backing up.
Noise that appeared suddenly points to a loose fan blade, a worn bearing or a mounting bracket that has come free. We open the casing, find the part that moved and tighten or replace it before it damages the housing.
Ice forms when the coil cannot absorb heat, either because airflow dropped or the charge is low. We defrost the unit, clean the filter and coil, then read the pressures before deciding whether gas is part of the fault.
A system that runs constantly and holds the room at the same reading has lost either its charge or the compressor's ability to pump. Suction and discharge pressures on the two sides tell us which of those it is.
A quote given before the testing is a guess, and a guess gets paid for twice. Our technician meters the circuit and the refrigerant side first, then puts a figure on the repair that fault needs.
Eight readings cover almost every fault on a split system. They take a few minutes each and they are what separates replacing the right part from replacing the expensive one.
How It Works
Four steps, and you approve the price before anything comes apart.
Call or WhatsApp +60178570744 with the make, the model and what you can hear or see. That tells us which parts to load into the van before we set off.
We confirm a slot that suits the household. For a shop or an office, we book outside trading hours.
Our technician meters the components in cost order and names the one that failed. You hear the part, what it does and what replacing it involves, then you decide.
We fit the part, run a full cooling cycle and read the temperature at the vent. The unit works before we pack up.

FAQ
If yours is not here, call or WhatsApp +60178570744 and we will answer it straight.
Most repairs finish in one visit. A capacitor, a contactor, a thermistor or a fan motor is a same-visit job. A leak repair on buried pipework needs longer, and so does a compressor change. You hear which of those yours is at the diagnosis.
An aircond trips the breaker when a component draws more current than the circuit allows. A shorted compressor winding, a failed capacitor and water sitting across the terminal block each produce that fault, and each needs a different repair.
No. The breaker is interrupting a fault current, and resetting it repeatedly puts the compressor and the cable at risk. Switch the unit off at the isolator and call us.
A start capacitor stores the charge that gets the compressor turning. Heat ages the material inside it until the capacitance falls below the rating on the can, and the compressor then hums without starting.
A failed compressor is replaced, because the unit is sealed at the factory and cannot be opened. On a system over ten years old, that replacement often costs more than a new aircond. We say so before you spend it.
Yes. An inverter system runs a variable-speed compressor through a driver board. The fault is traced through that board and the sensors feeding it, so the testing takes longer than it does on a fixed-speed unit.
An aircond that cools briefly and stops is reading a temperature that is not in the room. A drifted room or coil thermistor sends the board a false value, and the board shuts the compressor down early.
The outdoor unit runs while the room stays warm because the system cannot move heat outside. A low refrigerant charge, a condenser coil packed with dust or a compressor that no longer pumps each produce that result.
Cooling drops off again when the cause was never removed. Topping up gas without repairing the leak is the usual example, because the same charge escapes through the same joint within weeks.
No. Once the maker has stopped supplying the board or the compressor for a model, there is no repair we can stand behind. We say so at the diagnosis. Fitting a part that does not match the specification only moves the fault.
We need the make, the model and what the unit is doing. The model number sits on a sticker inside the front cover. Any code on the display tells us which parts to bring.
Yes. We work on wall-mounted splits and ceiling cassettes in shops, offices and other commercial premises. The visit fits around your trading hours.
