LG LAN121HNM Seal Kit
The seal kit will completely seal the unit from any outdoor air, which makes it quite a bit more proficient at heating or cooling and cost-friendly. Seal kits are easy to install and are the very best way to save you some money with your wall unit.
What to see if the system seal kit is in need of replacing?
- It seems to be taking longer to heat or cool the room
- You observe a lot of air getting through around the outside of the unit
- You can visibly see the outside while peering next to the LG unit
