INVERTER AC SERVICE
Inverter AC Repair in Kathmandu
Inverter systems use variable-speed drives, sensors, control boards, and communication between indoor and outdoor units. Accurate diagnosis matters because replacing the wrong board or compressor can be expensive.
Book Inverter AC RepairWe inspect inverter error codes, power electronics, sensors, fan control, compressor operation, refrigerant conditions, and communication before recommending parts.
Inverter AC problems we handle
Common symptoms include intermittent operation, flashing error codes, poor cooling, outdoor fan problems, unusual compressor speed, indoor-outdoor communication faults, and systems that stop after running for a short time.
- Inverter PCB and power module faults
- Indoor-outdoor communication errors
- Compressor or outdoor fan drive problems
- Thermistor and pressure-sensor faults
- Refrigerant or airflow conditions affecting protection logic
Why inverter diagnosis is different
A variable-speed system changes compressor and fan output according to demand. Voltage, current, sensor readings, communication signals, and fault history must be interpreted together. A visual inspection alone cannot confirm a PCB or compressor failure.
- Record model and error-code information
- Check supply quality and electrical connections
- Test sensors and communication circuits
- Review airflow, coil, and refrigerant conditions
- Match replacement boards to the exact model revision
Service coverage
Our engineering team supports AC systems across Kathmandu, Lalitpur, Bhaktapur and the wider Kathmandu Valley.
Frequently asked questions
Why does my inverter AC stop and start by itself?
Some cycling is normal as the inverter adjusts capacity, but frequent stopping may indicate a sensor, airflow, refrigerant, communication, electrical, or protection fault. Error codes and operating conditions should be recorded.
Can you repair an inverter PCB?
We can assess the PCB and related power, sensor, and communication circuits. Whether board-level repair or replacement is suitable depends on the model, fault, parts, and technician assessment.
Do you service Daikin, LG, Samsung, Midea and other inverter AC brands?
We provide multi-brand assessment and service support. Exact parts and repair scope depend on the model number and availability of compatible components.
