LG Aircon: Dual Inverter Technology Done Right

LG has grown rapidly in the Singapore aircon market thanks to their dual inverter compressor technology, which promises energy savings of up to 70% compared to conventional units. The DUAL Inverter Compressor operates on a wider frequency range, maintaining the desired temperature with less fluctuation and noise. However, this advanced technology requires knowledgeable servicing to maintain peak performance.

Our technicians are experienced with the full range of LG aircon systems popular in Singapore — from the standard S3-Q series wall-mounted units to the premium Art Cool Gallery with its customisable front panel. We also handle LG multi-split systems (Multi F and Multi V) used in larger homes and commercial spaces. Each model has its own service requirements, and we know the differences.

LG units also come equipped with features like the Plasmaster Ionizer+ air purification system and auto-cleaning function. These features need periodic attention during servicing to function correctly. We ensure every component — not just the basic filter and coil — is checked and cleaned during each visit.

Common LG Aircon Problems We Fix

LG units are built tough, but Singapore's climate creates unique challenges. Here's what we see most often.

CH Error Codes on Display

LG units show error codes on the LED display starting with "CH" followed by a number. CH05 (pipe sensor error), CH10 (fan motor issue), and CH38 (outdoor communication failure) are the most common. Unlike other brands that use blink patterns, LG's digital display makes it easier to identify — but the underlying repair still requires trained hands and proper diagnostic tools.

Auto-Clean Function Not Working Properly

LG's auto-clean feature runs the fan after cooling to dry the evaporator coil and prevent mould growth. When this function malfunctions or the unit isn't serviced regularly, mould builds up rapidly in Singapore's 80%+ humidity. You may notice a musty smell or visible black spots on the air vents. Professional chemical cleaning is the only effective solution.

High Electricity Bills Despite Dual Inverter

One of the top complaints from LG dual inverter owners is electricity bills that don't match the promised energy savings. This almost always traces back to dirty coils and filters forcing the compressor to run harder. A thorough servicing restores the energy efficiency your LG unit was designed to deliver — many customers see noticeable bill reductions after a chemical wash.

Water Dripping from Indoor Unit

LG wall-mounted units can develop water leaks when the condensate drain line gets blocked by algae or dust. The drain pan on certain LG models is also known to accumulate sludge faster in humid environments. We flush the entire drain system, clear any blockages, and apply anti-bacterial treatment to prevent rapid re-clogging.

LG Aircon Servicing FAQ

We recommend servicing your LG dual inverter aircon every 3 months. The dual inverter compressor is engineered for energy efficiency, but dust buildup on the evaporator coil and clogged filters reduce its effectiveness and force the compressor to work harder. Regular servicing maintains the energy savings that attracted you to the LG dual inverter in the first place.

LG aircon error codes starting with CH indicate specific faults. CH05 means an indoor pipe sensor error, CH10 means an indoor fan motor issue, and CH38 indicates an outdoor unit communication problem. CH21 and CH22 relate to the DC link voltage, while CH26 points to an outdoor unit inverter current overload. Our technicians can decode all LG error codes on-site and carry common replacement parts.

General servicing for LG aircon starts from $50 per unit. Chemical wash starts from $80 per unit. Gas top-up for R32 refrigerant (used in newer LG models) starts from $80 per unit. Visit our full price list for all rates including multi-unit discounts.

Yes, we service all LG aircon models including the Art Cool, Gallery, Artcool Mirror, and standard wall-mounted units. The Art Cool and Gallery series have a unique front panel design that requires careful handling during servicing — our technicians are trained to remove and reinstall these premium panels without scratching or damaging the decorative surface.

A clicking noise from your LG aircon is often caused by the unit's auto-cleaning function activating after the cooling cycle ends, thermal expansion of plastic parts during temperature changes, or a loose fan blade. Occasional soft clicking is normal for LG units. However, if the clicking is persistent and loud, it may indicate a failing relay switch or compressor issue that needs professional attention — contact us for a diagnostic check.
