Does mini split cost cost more in Kentucky?

A statewide residential code with local enforcement keeps requirements steady, but floodplain rules along the Ohio River add elevation and substantial-improvement review.

The formula
Cost = (total BTU / 1,000 x rate) + per-zone install labor + permit
Each additional indoor head adds equipment and labor, so a 3-zone system costs far more than a single-zone unit of the same total capacity.

Can I install a mini split myself?
DIY-ready kits with pre-charged line sets exist, but most jurisdictions still require a mechanical permit, and manufacturer warranties usually require licensed installation.
