Inverter AC Repair
Inverter air conditioners use a variable-speed compressor and electronic control boards, so faults often show up as error codes, weak cooling or an outdoor unit that will not start. We inspect inverter split ACs, find the fault and explain what it needs before any repair starts.
Common symptoms
- Error code or blinking lights on the indoor unit
- Outdoor unit not starting, or starting and stopping
- AC runs but cooling is weak
- Compressor or outdoor fan not running
- Tripping the breaker when switched on
- Remote and indoor unit not responding
- Water leaking from the indoor unit
- Unusual noises from the outdoor unit
Possible causes
- Faulty indoor or outdoor control board.
- Sensor faults (room, coil or outdoor temperature).
- Failed fan motor or fan capacitor.
- Communication fault between indoor and outdoor units.
- Low refrigerant caused by a leak.
- Unstable power supply or voltage problems.
- Dirty coils or filters reducing airflow.
How we diagnose and repair
- 1
We ask for the brand, model and any error code shown.
- 2
We check the power supply, indoor and outdoor units and wiring.
- 3
We test sensors, fan motors and the control boards.
- 4
We check refrigerant pressure and look for leaks.
- 5
We explain the fault, give an estimate and repair after your approval.
Repair or replace?
Many inverter faults come from sensors, fans, wiring or dirty coils, which are cheaper to fix than a board or compressor. If a main part needs replacing we explain the options and the cost compared with replacing the unit.
Switch the AC off at the breaker if you smell burning, see sparks or the unit keeps tripping the power. Do not open the outdoor unit or touch wiring and boards yourself. Inverter boards hold charge even after power is off.
Care tips
- Send us the error code or a photo of the blinking lights on WhatsApp.
- Clean the indoor filters regularly.
- Keep the outdoor unit clear of dust, leaves and blockages.
- Do not repeatedly restart a unit that is showing an error.
Questions about this service
What is the difference between inverter and non-inverter AC?
An inverter AC changes the compressor speed to hold the temperature, while a non-inverter unit switches fully on and off. Inverter units rely more on electronic boards and sensors.
Can you read my AC error code?
Send the brand, model and the code or a photo of the lights. Codes differ between brands, so we confirm the cause on inspection.
Is an inverter board repair or replacement better?
It depends on the fault and the unit age. We explain the options and the cost before any work starts.
Do you service inverter ACs, not only repair them?
Yes. See our AC maintenance page for cleaning and servicing.
Why is my inverter AC showing an error code?
Error codes point to a sensor, fan, communication or board fault. Codes differ between brands, so send us the brand, model and the code or a photo of the blinking lights.
Is an inverter AC more expensive to repair?
Faults on boards and compressors can cost more than on a basic AC, but many inverter faults are sensors, fans or wiring. We explain the options and the cost before any work starts.
