Starting condition

Open drywall cuts after mini-split AC installation

The indoor split AC unit was in place, but the surrounding drywall was left cut open with exposed edges and rough access areas below the unit.

This kind of repair needs careful patching because the wall has to be closed neatly around existing AC lines without creating a bulky or uneven finish.

Scope of work

  • Drywall opening assessment after mini-split installation
  • Patch sizing and fitting around the AC lines and wall opening
  • Drywall patch fastening and surface preparation
  • Joint compound and skim-coat work
  • Drying time between repair stages
  • Interior wall painting and final cleanup
Before

Before: open drywall around the AC unit

The repair started with visible cutouts, rough drywall edges, and an unfinished wall below the indoor mini-split unit.

Repair process

Patch, compound, dry, prep, and paint

Repair Asap measured the damaged area, cut and fit drywall patch pieces, and fastened the wall repair around the existing mini-split lines.

The patch was covered with joint compound and allowed to dry between stages before the surface was prepped for paint.

After painting, the wall read as a finished installation instead of an open construction cutout.
