Those are beautiful looking units. It's a cool idea to focus on giving something very pedestrian and utilitarian a nice cosmetic overhaul.
I just replaced radiators with a heat pump install. I had a few questions about your units: What are "backup heating strips?" They're mentioned in passing when talking about cold weather, but I imagine there is some meat here. Also, even though many heat pumps work in cold weather, their efficiency drops. Where is the break even point? Also, what is the sound level of the condenser unit? It looks like you only list sound levels for the air handler.
