(Why don't we show the price?)

Retailers have the legal right to set their own prices, but some manufacturers place restrictions on how those prices may be communicated. Because our price on this item is lower than the manufacturer's “minimum advertised price,” the manufacturer does not allow us to show you our price until you place the item in your cart, or in some cases, proceeding to the final checkout stage. Taking these steps allows Appliances Connection to show you our price consistent with our goal of always offering you the lowest possible prices on the widest selection of products. You are not required to purchase the product to see our lowest price, simply just remove it from your cart.

LG inverter Mini Split Air Conditioning models use a variable speed compressor which is quieter to operate and uses less energy than conventional air conditioners. When the selected temperature is reached, instead of shutting off, the inverter compressor operates at low speed to maintain that comfort level. This inverter model has efficiency ratings of 18 SEER, making this unit the most energy efficient in its class. This product comes with one of the best warranties in the industry! The warranty provided will be 5 years on the parts and 7 years on the compressor.

Hard installation but the best of the best

By  from Jersey City, NJ, United States  Verified Owner
Overall Rating: ☆☆☆☆☆ ★★★★★ 5

Recommended Product:

Excellent unit in terms of its cooling power. One con is that it is very hard to install by yourself. You will have to get someone who know what he or she is doing. This is not a plug and play unit. Other than that the unit is terrific once installed.
