Buying notes
- Labor is priced per zone because each zone is its own line set, vacuum, and electrical decision - that is why installed totals climb faster than equipment prices.
- A true-DIY single-zone (first row family in our dataset) collapses most of the labor line; multi-zone DIY claims need the line-set caveat in the DIY guide.
