Friedrich SM21 Seal Kit
A seal kit will completely seal the unit from the air outdoors, which makes it quite a bit more proficient at heating or cooling and will reduce the cost of utilities. Most seal kits are really simple to install and are designed to save money while your unit is running.
What warnings are present when my system seal kit needs replacing?
- It could be requiring more time to get to the right temperature in your home
- You can feel a good size airflow making its way to the house from around the outside of the unit
- You can visibly see outside while being next to the unit
