LG LAU121HNP Seal Kit
A seal kit can seal from any outdoor air, thus making it much more efficient and much cheaper to keep running. These kits are quite simple to set up and were created to help save expenses running your unit.
Major signs of a poorly operating thermal seal kit
- It is needing a lot more time to get to the right temperature in your home
- You notice too much of an airflow is getting in the house from around the outside of the unit
- You can actually see the outdoors while being next to the unit
