Williams 7691 Seal Kit
The seal kit would help seal the unit from the outside, which makes it quite a bit more proficient at heating or cooling and easier on the wallet. Most seal kits are really simple to install and are designed to save energy and to save you some money while operating your wall system.
Elements of a poorly working thermal seal kit
- You detect there is unwanted air being allowed to come indoors from next to the unit
- You can actually see the outside while being beside the Williams system
- It may be demanding more time to reach the desired temp in your home
