Ultra quiet operation is the hallmark of LG's new line of PTAC products. Low decibel levels and an outstanding sound prevention rating make this your best choice for a quiet environment. And with efficiency ratings up to 11.9 EER, these units are also your energy efficient choice. Other features include standard connections for remote thermostat and front desk controls. Gold Fin technology protects the unit from the corrosive effects of outside air and extends the operating life of PTAC models. And the industry standard size makes installation easy and economical. Wall Sleeves and Exterior Grilles are Needed for New Installations (Sold Separately).   Available at AppliancesConnection


LG PTAC units are an economical way to cool and/or heat your rooms. Whether assessing construction costs, maintenance costs, or operating costs, PTACs allow for the flexibility to control energy expenses room-by-room, rather than building-by-building. If you need service or maintenance, the units easily slide out of the sleeves and can be replaced simply by sliding in a new unit. The dual air filters are front-loaded for easy cleaning, and can be interchanged left or right. LG was among the first manufacturers to include a cross-flow fan for quiet operation, and continues to add innovative improvements to maximize your investment and control your energy use.
