I'm a handy guy and can do pretty much anything around the house that I put my mind to. Assuming I can handle the part of the install that is outside (the concrete pad, the hole in the crawlspace wall, the electric), is it realistic for a handy homeowner to run flexible ductwork throughout a small (1000 sq. foot) house and hook the whole thing up? What are the most likely mistakes a newbie would make in this process? If you're willing to blur the line between homeowner and HVAC tech, sure. If this is a split system, hooking up the linesets, purging the lines with compressed nitrogen, pumping it down, measuring the vacuum, adjusting the charge, and ensuring that the system is leak-free are all likely to be the most challenging parts. These tasks require specialized tools and knowledge. You can certainly get the tools and acquire the knowledge, but once you do that, you're basically as good as an HVAC guy, many of whom don't actually know how to do this stuff very well themselves.
