Do you sell plenums for package units?

You do not use a formal plenum with a packaged unit. What you would use depends on the type of home or building its conditioning. Where the unit is set up is also a key component. If the packaged unit is installed on the ground beside a building, you can optionally use square-to-round adapters to connect the unit to your building. Please note that these adapters are required for Mobile and Manufactured Homes. If the packaged unit is installed on top of a building, a roof curb is required. These adapters and roof curbs are what a packaged unit would use instead of a plenum.

If you have any further questions, please call us and we will be happy to assist you.
