Common FAQs

What size room is the LG H18TN4-18K air conditioner suitable for?

The 18,000 BTU cooling capacity is designed to cool larger spaces ranging from 25 to 38 square meters (270–400 sq ft), making it ideal for spacious living rooms, open-plan apartments, large offices, or commercial reception areas.

What benefits does the R32 refrigerant offer in this unit?

R32 refrigerant provides higher energy efficiency and superior heat conductivity compared to older refrigerants like R410A, while drastically reducing the environmental impact due to its low Global Warming Potential (GWP).

How does JetCool work on the 18,000 BTU model?

When activated, JetCool runs the blower fan and compressor at maximum speed to blast high-velocity cool air throughout the room, dropping the temperature in minutes before returning to standard operation.

Why is the Gold Fin™ coating important for outdoor units?

The Gold Fin™ protective layer guards the outdoor aluminum heat exchanger coils against rust and corrosion caused by coastal humidity, rain, and environmental pollutants, ensuring long-lasting performance and efficiency.

What is the difference between this 18K model and the 12K model?

The main difference is cooling output: the 18,000 BTU unit produces 50% more cooling capacity than the 12,000 BTU model, making it suitable for significantly larger rooms or spaces with high occupancy and sun exposure.
