AC repair & faults in Al Naseem

The technician measures the capacitor's microfarad value and compares it with the figure printed on the casing. If the reading is low, the capacitor is replaced first and the unit is retested. The compressor is only judged after confirming the surrounding circuit is sound, and this sequence prevents replacing an expensive part without reason.

Cleaning alone is not enough if the drain line does not have the right fall or the drain tray has a small crack. We follow the water path from the tray to the outdoor drain outlet and check the fall at every section. Sometimes the indoor coil freezes and thaws because of poor airflow, which is a different cause and needs a different check.

It depends on the type of sound. A click at start-up is often plastic expanding with heat; a continuous hiss may point to a leak at a joint; a rattling sound usually means something caught in the fan or a fan that needs balancing. The technician describes the cause after listening and checking both units.

There is no fixed rule, but we consider the unit's age, the refrigerant type written on its nameplate and the cost of the repair against the price of a new unit. If faults keep returning or the refrigerant type is hard to source, replacing makes more economic sense. The technician lays the calculation out clearly before any decision is made.

A musty smell usually comes from bacterial growth on the evaporator coil or a stagnant drain tray, which is a cleaning matter. But a burning or hot-plastic smell points to heat in the electrical circuit or a component about to fail, and in that case a fault technician must inspect the unit before it is run again.

Refrigerant leaks are the most common cause, usually in the copper joints from salt corrosion in the coastal air. We test the entire circuit to locate the leak before repairing it and recharging.

Usually the drain line is clogged by fine dust and algae in the drain filter, especially in Al Naseem's high humidity. We remove the drain pan, clean it, clear the filter and check the pipe gradient.

Yes, units on sea-facing façades suffer faster salt buildup on the coil and copper joints, causing corrosion and leaks. Regular cleaning and periodic inspection of the joints cuts that damage significantly.

Bad smell usually comes from bacterial or mould growth in the drain pan or evaporator coil due to coastal humidity. We inspect the drain and coil, clean as needed, and may add a safe biocide if required.
