Williams 3003622 Seal Kit
The seal kit can actually seal the entire wall unit from the outside, in turn making it more effective and will yield a cost-saving benefit in the long run. Seal kits are really simple to install and were devised to help save expenses heating or cooling your house.
What are the signs that the thermal seal kit is not working?
- You can visibly see what is happening outside while being beside the Williams system
- You can tell that there is unwanted air getting through next to and around the unit
- It seems to be needing more and more time to arrive at the desired temperature in the room
