Doing some good work. Hope you find some investment or partnership with some trusted appliance names. Sounds like you'll be subbing out installation, I wish you luck building and protecting your brand reputation.

I'm an edge case in Bay Area, don't have ducts, so looking at ceiling cassettes. I'll go learn about vapor injection compressors now.

Thanks for the support! Vapor injection is cool - if that's interesting look at some other novel architectures like cascade cycles, hot gas bypass, and internal heat exchangers.
