Why LG Is Popular With Yishun Homeowners
LG has established itself as a strong contender in the Singapore aircon market, and Yishun homeowners have increasingly chosen the brand for its combination of advanced technology, sleek design, and competitive pricing. LG’s Dual Inverter compressor technology appeals to cost-conscious homeowners across Yishun’s HDB estates who want energy-efficient cooling without the premium price tag of some Japanese brands. The brand’s smart home integration through LG ThinQ also resonates with younger homeowners moving into new BTO flats at Yishun Boardwalk and Yishun Beacon.
Billy Aircon Yishun is a dedicated local team led by Thomas Lim, a BCA-certified technician with 10 years of experience. We are part of Billy Aircon — a licensed aircon servicing company since 2003. Our technicians are familiar with the full range of LG residential and light commercial models, from standard wall-mounted split units to the designer Artcool series. We understand the specific engineering of LG’s Dual Inverter compressor and the electronic control systems that manage it, enabling us to diagnose and fix issues that general technicians might struggle with.
LG’s newer models use R32 refrigerant, while some older units still run on R410A. Our team is certified to handle both refrigerant types and carries the appropriate equipment for each.
Models and Systems We Service
LG Dual Inverter Series
The Dual Inverter is LG’s core residential aircon technology. Unlike conventional inverter compressors that use a single rotary mechanism, LG’s Dual Inverter uses two rotors to compress refrigerant. This design reduces vibration, lowers noise levels, and improves energy efficiency. LG backs this compressor with a 10-year warranty. During servicing, we monitor the compressor’s operating parameters, as the dual-rotor design has specific current draw patterns that help us identify early signs of wear. These units are becoming the standard choice in Yishun’s newer HDB and condo developments.
LG Artcool Series
LG’s premium designer aircon range. The mirror or glossy front panel doubles as a statement piece in modern interiors — popular in renovated Yishun apartments and condos near Khatib. Servicing the Artcool requires extra care when removing and cleaning the front panel, as the mirror surface can scratch if handled roughly. We use microfibre cloths and non-abrasive cleaning solutions on these panels.
LG Smart ThinQ-Enabled Units
Many LG models come with built-in Wi-Fi and support for the LG ThinQ smartphone app, allowing remote control, scheduling, energy monitoring, and maintenance alerts. While the smart features rarely require servicing, the ThinQ system provides useful diagnostic information that helps our technicians identify issues faster. If your LG aircon sends you an alert through the ThinQ app, share the code when you book your service call with us.
LG Multi-Split and Ceiling Cassette Systems
LG offers multi-split systems (System 2, System 3, and System 4 configurations) popular in Yishun condos where condenser mounting space is limited. LG also provides ceiling cassette systems for commercial spaces at Northpoint City, A’Posh BizHub, and retail units across Yishun. Both system types require thorough servicing that accounts for refrigerant distribution across multiple indoor units.
Common LG Aircon Problems in Yishun
LG Aircon Water Leak
Water leakage from the indoor unit is the most common LG service call in Yishun. The high ambient humidity means the evaporator coil produces heavy condensation throughout the day. When the drain pan or drain hose becomes blocked with algae and slime — which grows rapidly in the warm, moist conditions — water overflows and drips from the unit. The older HDB blocks along Yishun Ring Road and Chong Pang are especially prone to drainage issues. We flush the drainage system, apply anti-microbial treatment, and verify that the drain pipe has adequate slope for gravity flow.
LG Aircon Not Cooling Properly
When your LG aircon is not blowing cold air, the Dual Inverter compressor may not be the problem. More often, the cause is a dirty evaporator coil that restricts heat exchange, a clogged air filter reducing airflow, or low refrigerant due to a slow leak. Our technicians systematically check each component before concluding whether the issue is mechanical or requires a gas top-up.
LG Error Codes
LG aircon units display error codes on the indoor unit’s panel or through the ThinQ app. Common codes include CH 05 (communication error between indoor and outdoor units), CH 10 (indoor fan motor fault), CH 21 (Dual Inverter compressor overcurrent), and CH 38 (outdoor temperature sensor error). When you contact us with an error code, we can pre-diagnose the issue and bring the necessary replacement parts on our first visit.
Dual Inverter Compressor Issues
While LG’s Dual Inverter compressor is reliable, it can develop issues over time. Problems include the compressor not reaching full speed due to a faulty inverter board, excessive vibration from worn internal components, or thermal overload protection trips. In Yishun, outdoor units installed in poorly ventilated condenser ledges on older HDB blocks are particularly prone to overheating during peak afternoon hours. We check the installation environment and recommend improvements if the condenser airflow is restricted.
Ice Formation on Evaporator Coil
Ice forming on the evaporator coil causes reduced cooling and can lead to water leaks as the ice melts unevenly. This is typically caused by low refrigerant pressure from a gas leak or severely restricted airflow from a clogged filter. Running the unit at very low temperature settings with a dirty filter increases the risk significantly. We identify and fix the root cause — whether it is a gas leak, dirty coil, or blocked filter.
Trusted by Homeowners Across Yishun
Our Yishun team has built focused expertise in LG aircon systems through consistent hands-on servicing across the Yishun planning area. We understand the specific characteristics of LG’s Dual Inverter technology, the electronic control board architecture, and the refrigerant charge requirements for each model. This experience means faster diagnosis and fewer return visits.
We stock commonly needed LG replacement parts, including thermistors, fan motors, PCB boards, capacitors, and drain pumps. Service coverage extends across Yishun, Khatib, Nee Soon, Springleaf, Lower Seletar, and nearby areas including Sembawang and Mandai. We work in HDB flats, BTO estates, private condos, and commercial buildings throughout the North Region.

LG Servicing Rates in Yishun
Standard Servicing - from $50 per unit
Standard servicing for LG includes filter cleaning, evaporator coil cleaning, drain pan flushing, condensate pipe clearing, and outdoor unit inspection. We measure the airflow temperature to verify cooling performance and check the Dual Inverter compressor’s operating current. Recommended every 3 months in Yishun’s tropical climate. Check our complete servicing price list.
Chemical Wash - $80 to $100 per Unit
A chemical wash removes stubborn biofilm, mould, and grease deposits that accumulate inside the evaporator coil. Particularly effective for LG units in older Yishun homes where contamination has built up over months of use. Full chemical overhaul ($130 to $180) provides a complete dismantle-and-clean process for severely contaminated units.
Gas Top-Up - From $80
Accurate R32 and R410A gas top-up using calibrated digital gauges. We always perform a leak check before adding refrigerant — adding gas to a leaking system is wasteful and only provides temporary improvement.
Repairs and Parts Replacement
Fan motors, thermistors, PCB boards, capacitors, swing motors, and drain pumps. All repairs include a 90-day warranty on parts and labour. For units beyond repair, we provide aircon installation services.
