Also, would there be a problem mixing a High Velocity system with a conventional AC ducted system? I know it is not necesarily the most elegant solution, and I will continue to look for alternatives, but was wondering if it would cause a problem?

He's calculating a total of 4.5 tons needed for the existing structure and the addition. His suggestion, put in a conventional heat pump into the addition (2.5ton) and try to duct some into the existing structure. Sounds like the cost is going to be prohibitive to upgrade the chiller and the Spacepak.
