LG 9K BTU Cooling 22.2 SEER2 One Zone Ceiling Cassette Mini Split Package with Inverter Technology and Gold Fin Protection

his is a single-zone ductless mini-split heat pump system from LG, using a four-way ceiling cassette indoor unit. Instead of a wall-mounted unit, the indoor cassette is mounted recessed into the ceiling with a grille, distributing air in four directions. It uses inverter technology and R-32 refrigerant.ACWholesalers+2device.report+2

“Gold Fin Protection” is included, which is LG’s corrosion-resistant coating on the heat exchanger to improve durability against the elements.ACWholesalers+2device.report+2

Key Specifications

Here are the important performance and technical specs:

Features & Extras

Some of the user-friendly / value-adds include:

• Four-Way Airflow: The ceiling cassette pushes air in four directions, which gives more even distribution in the room. Good for larger, more open areas or rooms with multiple seating zones.ACWholesalers+1

• Inverter Compressor + Variable Speed Fan: Helps maintain set temperature without cycling on/off too much; more efficient, quieter, smoother operation.device.report+1

• Gold Fin Protection: For corrosion resistance (especially on the outdoor unit’s heat exchanger), which helps in humid/salty or harsh climates.ACWholesalers+1

• Condensate Pump Built In: Indoor unit includes condensate pump (~27.5" of lift) to remove drip-off from the ceiling cassette, which is necessary since drainage may not naturally go downward.ACWholesalers+1

• Sleep / Timer Modes: Helps save energy during night or when full cooling/heating isn’t needed.eComfort+1

• Dehumidification Mode: The system can reduce humidity without overcooling.ACWholesalers+1

• Leak Detection Sensor: R-32 units include a sensor to detect refrigerant leaks.SupplyHouse.com+1

• Quiet Operation: Both indoor and outdoor units are designed to be relatively quiet. This includes brushless DC fan motors and low sound designs.ACWholesalers+1

Pros & Things to Like

• Efficiency & Lower Operating Cost: Because of the high SEER2 and good HSPF2, likely lower energy bills especially in cooling season.

• Ceiling Cassette Aesthetics / Distribution: Minimal visibility inside room; only the grille shows. Distributes air well in all directions.

• Better Heating Performance in Colder Conditions: Rated to continue heating down to very cold outside temps (around −4°F), which is helpful if you’re in a colder climate.

• Durability: With features like Gold Fin, leak detection, etc., this unit is built more solid than basic mini-splits.

• Modern Refrigerant (R-32): Less environmental impact, may comply better with evolving codes/regulations.

Cons / What to Watch Out For

• Higher Upfront Cost: Ceiling cassette style and added features cost more than simpler wall units. Installation is more involved.

• Ceiling Height / Access: Needs enough ceiling clearance to recess the cassette; plumbing, drainage, and wiring must be routed appropriately.

• Sound in the Ceiling Plenum: Even though indoor unit is quieter, air blowing across four outlets may produce some noise in vents / grille. Not usually loud but may be more noticeable.

• Maintenance: Filters, condensate pump, coil cleaning will be more involved than wall-units in some cases. Need access upward.

• Cold Weather Performance: Although rated to low outdoor temps, performance (heating capacity) drops off as with all heat pumps in cold conditions; may need backup heating in very cold climates.

• Electrical / Wiring Requirements: Must ensure proper breaker size, cable, conduit, etc. Also needs a proper line set, every connection sealed well.

Is It a Good Pick?

Given all of that, this unit is well suited for:

• Rooms/areas of moderate size (roughly 350-500 sq ft given good insulation), especially where you want ceiling-mounted, discrete distribution.

• Locations where both cooling and heating are needed, and where winters are cold but not extreme (or where supplemental heat is acceptable).

• Contexts where you want modern, efficient refrigerant (R-32) and want to meet stricter efficiency standards.

• Situations where aesthetics matter (ceilings, not wanting wall units, preserving wall space).
