Reviewed ductwork again in attic space. Found sevral ducts kinked and design and install is poor. Best solution would be to replace duct syalstem and design for zoning left to right. Provided ballpark pricing of 15-20k for this. Murali just would like to clean up ducts as much as possible and relocate some ducts on main floor. Also would like to add a register in basement off if master bedroom system. Need to provide load calc on this. Also took some initial airflow neasurements.
