Friedrich SH20L30-A Seal Kit
A seal kit seals the whole system from the outside, which makes it quite a bit more effective and will save you money too! These seal kits are really simple to install and are designed to save energy and to help reduce expenses with your wall unit.
Major indications of an inadequate system seal kit
- You detect quite a bit of air is making its way to the house from next to the unit
- You can see the outdoors while peering beside the system
- It seems to be demanding more time to get to the right temperature in the main areas
