AC Not Cooling
The blower fan runs, but it only circulates room temperature air. We check the compressor, capacitor, cooling coils, and refrigerant levels.
AC Cooling Less
Cooling feels weak or takes several hours to drop the room temperature. Usually caused by choked filters, dirty coils, or slightly reduced gas pressure.
AC Not Starting
The unit does not respond when switched on from the main board or remote. We test the power supply, voltage stabilizer, fuse, and PCB.
AC Suddenly Stopping
The AC runs for a few minutes and then trips or shuts off. This can happen due to compressor overheating, faulty sensors, or voltage fluctuations.
AC Water Leakage
Water drops from the indoor split AC unit or leaks inside the room. Caused by choked drain trays, bent drain pipes, or ice melting inside the unit.
AC Gas Leakage
Refrigerant gas escapes from copper pipe joints or cooling coil pinholes. We check for leaks before suggesting any gas refilling.
AC Making Noise
Rattling, humming, or buzzing sounds from the indoor blower or outdoor unit. We check blower balance, motor bearings, and loose casing screws.
AC Bad Smell
Foul, musty, or moldy odor coming from the blower vents. Dust, moisture, and fungus on the cooling coil need thorough cleaning.
AC Remote Not Working
The AC display does not respond to temperature change or mode buttons. We check the remote infrared signal, display board, and receiver sensor.
AC Fan Not Working
The indoor blower fan or the outdoor condenser fan does not spin. Caused by a weak fan capacitor, jammed motor, or damaged motor wiring.
AC Compressor Problem
The compressor fails to start, makes loud humming sounds, or runs hot. We check the starting capacitor, overload protector relay, and motor coils.
AC PCB Problem
The electronic circuit board fails to send signals to the compressor or fan. Our technician checks the PCB for burn marks, loose relays, or faulty components.
AC Sensor Problem
The room temperature sensor or coil defrost sensor gives wrong readings, making the AC cut off too early or freeze up continuously.
AC Tripping Power / MCB
The main electricity breaker (MCB) trips the moment you turn on the AC. We check for short circuits, compressor grounding, or damaged electrical wires.
AC Error Codes
Display shows error codes such as E1, E2, E4, E6, F3, or blinking LED light patterns. We match the error code to the manufacturer chart to find the faulty part.
AC Ice Formation
Thick white ice builds up on the indoor cooling coil or outdoor thin copper pipe. This happens when airflow is choked or gas pressure is low.
Outdoor Unit Problem
The outdoor unit fan or compressor does not turn on even when the indoor unit is running. We test the communication wire, contactor, and capacitor.
Indoor Unit Problem
The indoor unit makes rattling sounds, has broken louvers, or the display is blank. We inspect the indoor casing, blower wheel, and display wiring.
Drainage Problems
Condensation water backs up because of dirt or slime in the drain hose. We flush the line and adjust pipe slope for smooth water exit.
Airflow Problems
Very little air blows out from the vents, even at maximum fan speed. We clear choked filters, wash dusty blowers, and clean cooling coil fins.
