Local factors in Louisville, KY
Louisville sits in the South Central region, where long hot seasons and, in parts of the region, hurricane or severe-storm codes affect material specs and inspection requirements. For home systems (HVAC, electrical, plumbing) projects like this one, that generally means equipment and code compliance usually drive the price more than labor hours, so ask contractors which brand/efficiency tier they're quoting.
