Packaged Heat and AC Unit!- How to Seal it up to a House or Mobile Home!

Packaged Heat and AC Unit!- How to Seal it up to a House or Mobile Home! This is how to seal up the connection between the Packaged unit and the home or building. This stops animals from getting in and making nests inside the ductwork or ripping the insulation out. Also, you need some type of connection for weatherization purposes and also to shield the duct and duct wrap from getting all wet and rotting where it meets the Package Unit at. Make a nice shroud connection to seal up to the home to look professional, keep the animals out, and increase the weather barrier!
