Williams 5009621 Seal Kit
A seal kit seals the unit from the outdoor environment, in turn making it more proficient at heating or cooling and will reduce the cost of utilities. Most seal kits are quite simple to set up and were mainly created to help you to save you some money letting your unit run.
