Mc Williams & Son. Installed AC Unit and ductwork.
The Plentum Box #1: Was not sealed at all! 1/4 crack by the Plenum Box, cracks on all sides.
The Plentum Box #2: The metal piping connecting to the Plentum Box in the attic was not flush with the box, which means cold air was going straight into the
attic, no sealant.
DUCTWORK PIPING:
NOT CONNECTED at joints or vents!
Absolutely no sealant, tape or mastic or silicone, NOTHING
