The LG 1.5 Ton DUALCOOL Inverter T3 Split Air Conditioner (Model: S4UQ18KL30A / S4-Q18KL3QA) is a premium, technology-driven climate control system. Engineered specifically to tackle the severe summer heat waves of tropical regions like the Gulf, it blends LG's signature variable-speed power engineering with robust voltage protection.

DUAL Inverter Compressor with 10-Year Warranty

•  Unlike traditional single-rotary inverters, LG’s Dual Inverter uses twin rotators operating at a wider rotational frequency range. This structural balance drastically cuts down operational vibrations, accelerates initial cooling speeds by up to 40%, and reduces total electricity consumption by up to 70% compared to standard fixed-speed units. 

GEN Mode (Generator / Ampere Limiter)

•  A highly practical power-management setting. GEN Mode lets you manually throttle the maximum current draw of the AC. This allows you to safely run the unit on a local backup generator or keep it running alongside other high-load kitchen appliances without overloading your home circuit breakers.

Volt Care Triple Safety Protection

•  Built with integrated electrical safety buffers including a Low Voltage Starter (LVS) and High Voltage Safe (HVS) protection. This onboard system safeguards the sensitive inverter PCB and compressor from power grid spikes, brownouts, and severe voltage fluctuations, eliminating the need for an external stabilizer.

Gold Fin Anti-Corrosion Armor

• The outdoor condenser coil fins are layered with a specialized gold-colored hydrophilic epoxy coating. This surface prevents condensation water from gathering, blocks salt-air oxidation in coastal zones, and thwarts early rust decay to keep thermal exchange running at peak levels.

Comfort Sleep & 6-Step Vertical Louver Control

• Provides a customized sleep environment. The motorized horizontal vane can be locked into any of 6 precise preset angles, directing the cold air upward toward the ceiling so it falls naturally like a gentle shower, rather than blasting freezing drafts directly onto your bed.

Automated Internal Clean

•  When you switch the unit off, the interior fan continues running on a low cycle for a brief period to thoroughly dry out any condensation moisture left on the indoor evaporator coils. This stops mold, bacteria, and sour, musty odors from multiplying inside the chassis.

Refrigerant

•  Uses R410a, an eco-friendly and highly efficient refrigerant for modern cooling systems.
