Williams 2509822 Seal Kit
A seal kit can actually seal the entire wall unit from any outdoor air, thus making it much more energy efficient and cheaper to run. These seal kits are really simple to install and are designed to save energy and to save money operating your HVAC system.
What are some hints that my unit seal kit is not operating as it should?
- You can actually see what is happening outside while standing beside the unit
- It sure seems like it is needing a lot more time to heat up or cool down the room
- You notice too much unconditioned air is being let through next to and around the unit
