LG Air Conditioning Repairs & Installation
Repairs, servicing and installation for LG split systems and ducted units — certified technicians across Queensland.
Trusted Experts in LG Repairs & Installation
LG is one of Australia’s most popular air conditioning brands, offering a wide residential range from the energy-efficient Dual Cool inverter series through to the premium ArtCool and multi-split configurations. Jaric installs LG systems across Queensland, giving our technicians a deep understanding of how these units are built and how they perform.
That installation familiarity is a direct advantage when something needs repairing. Our technicians know the LG range from commissioning through to fault diagnosis — which means faster identification of the problem and repairs carried out correctly the first time.
We stock common LG components on our vans and provide a clear, upfront quote after the diagnosis before any work begins. And if your unit is beyond repair, we can supply and install a new LG system without you needing another contractor.
Common LG Faults We Fix
If you’re experiencing any of the following with your LG unit, our technicians can diagnose and repair it. If your specific fault isn’t listed, book a diagnosis and we’ll identify the issue on arrival.
Error codes (CH codes)
LG units display CH-prefix alphanumeric error codes to indicate specific faults. CH01/CH02 typically point to temperature sensor faults; CH05 indicates a communication error; CH38 indicates an outdoor unit fault. Our technicians know the LG fault code system and arrive prepared for the most common fault types.
Refrigerant leaks
Refrigerant loss is among the most common LG split system faults, presenting as reduced cooling, the indoor unit icing up, or short-cycling. We locate the leak, repair it, and recharge to LG’s specified refrigerant weight.
Dual Cool compressor faults
LG’s Dual Cool Inverter compressor technology is highly efficient but can develop faults that cause the outdoor unit to shut down under load or fail to maintain temperature. We carry out a full refrigerant and electrical assessment before confirming a compressor fault.
PCB and control board faults
PCB failures can cause erratic unit behaviour, units that won’t respond to controls, or repeated error codes that don’t point to a single sensor fault. We carry replacement control boards for common LG models and can test boards on site before committing to replacement.
Drainage and condensate leaks
Blocked condensate drain lines are a common service issue across the LG residential range. We clear blockages, clean the drain tray, and check the drainage pitch as part of the service.
ArtCool panel faults
LG ArtCool indoor units have a distinctive glass panel design that can develop specific faults including display issues and panel sensor errors. Most ArtCool faults are component-level repairs rather than full unit replacements.

Frequently Asked Questions
My LG air conditioner is showing an error code. What does it mean?
LG units display alphanumeric error codes on the indoor unit when a fault is detected. Note down the code when you book — it helps us identify the fault and arrive prepared with the right parts.
Do you repair LG Dual Cool and ArtCool models?
Yes — we service the full LG residential range, including the Dual Cool inverter series, ArtCool, and multi-split configurations. Our technicians are familiar with their common fault patterns.
My LG unit won't connect to the app or respond to Wi-Fi controls. Can you fix that?
Connectivity issues with LG’s ThinQ-enabled units can stem from a control board fault, a firmware issue, or a wiring fault in the indoor unit. Our technician will diagnose the root cause. Note that we repair hardware faults — network configuration is a separate matter.
Do you install LG air conditioners as well as repair them?
Yes — Jaric supplies and installs LG systems. If your unit is beyond economical repair, we can advise on a replacement from the current LG range and carry out the full installation.
