LG LS301CE Seal Kit
The seal kit can actually seal the entire wall unit from the air outdoors, which makes it quite a bit more efficient and will reduce the cost of utilities. Most seal kits are quite simple to set up and are designed to reduce the overall cost of heating or cooling your house.
Signals of a defective wall seal kit
