AC repair & faults in Al Majd

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.

It could be low refrigerant or the condenser blocked by desert dust, both cutting cooling power. We check the pressure and condenser and identify the cause before topping up refrigerant or cleaning the unit.

Yes, we regularly access roofs and high balconies. We check the access route and structural safety before going up, and we need confirmation that the roof is safe and reachable before the appointment.

Yes, desert dust clogs the condenser and raises operating temperature, which can damage the compressor over time. We clean the condenser and recommend protective covers during dust storms or long shutdowns.

Longer copper runs increase flow resistance and heat loss, but normal distances up to 10, 15 metres pose no obvious problems. We inspect the insulation and joints carefully, since leaks from longer pipes can occur sooner.
