What needs fixing?

Aircon cleaning removes dust, dirt, and mold from the filters, coils, blower, and drain line. It is routine upkeep, not a repair, and usually takes one to two hours per unit. Most homes in the Philippines book a cleaning every six months, or every three months if the unit runs daily near traffic or dust.

Installation covers mounting the indoor and outdoor units, running the copper tubing and drain line, electrical connection, and a cooling test. A clean install matters more than the brand. Correct sizing, bracket height, and pipe length affect cooling, noise, and how often the unit needs repair later.

Aircon maintenance is preventive care that combines cleaning with inspection and testing. It catches loose wiring, dirty coils, weak airflow, and small refrigerant leaks before they become repairs. Most homes need it every six months. Maintenance keeps a working unit efficient, but it cannot fix a failed part.

The compressor is the pump that moves refrigerant through the system. Not every unit that blows warm air needs a new one. Diagnosis checks the capacitor, relay, wiring, power supply, and refrigerant charge first. Replacement is advised only when the windings are open or grounded, or the pump is mechanically seized.

There are two kinds of aircon leaks. Water leaks usually come from a clogged drain line or a tilted indoor unit. Refrigerant leaks come from flare joints, tubing, or coils. A refrigerant leak needs a pressure test and repair before any recharge. Topping up gas without fixing the leak only delays the problem.

The condenser is the outdoor coil that releases heat from your room. If it is dirty, blocked, or its fan is weak, the unit cools poorly and the compressor runs hot. Repair can mean cleaning, a fan motor or capacitor replacement, or coil repair. It is different from indoor unit cleaning.

The PCB controls the fan, compressor, sensors, and display. A board is not automatically bad because the unit will not start. Diagnosis checks the power supply, fuses, relays, sensors, and error codes first. Some faults can be repaired at component level. Replacement is for burned or unavailable boards.

A sealed aircon system should not lose refrigerant. If cooling drops, the usual cause is a leak, not old age. A proper recharge means finding and fixing the leak, vacuuming the line, then charging by weight. Topping up without a repair buys a few weeks of cooling, no more.

Window units are simple and usually repairable. Common faults are a dirty filter, a failed capacitor, a weak fan motor, a clogged drain, a thermostat problem, or a failing compressor. A technician can test the unit on site and quote before any part is replaced. Most repairs take under a day.

Split systems have an indoor and an outdoor side. Indoor faults show as weak airflow, water leaks, or noise. Outdoor faults show as no cooling, tripping, or a hot compressor. Diagnosis checks both sides before parts are replaced. Typical repairs cover the PCB, fan motor, sensors, drain pump, and compressor.

Portable units are compact but still have a compressor, fan, PCB, and drain system. Common problems are a full water tank, a kinked exhaust hose, a dirty filter, a weak fan motor, or a control board fault. Some issues are fixed at home. Parts can be harder to source than for window or split units.

HVAC and VRF covers multi unit systems in offices, shops, and buildings. Service includes preventive maintenance, fault diagnosis, controls, and repair across indoor and outdoor units. VRF systems need error code diagnosis and refrigerant records. Work is usually scheduled outside business hours to avoid disruption.
