Repair larger holes in wall?

[Mjärn]

Today a refrigeration technician will come and move an air source heat pump. This means there will be a larger hole in the wall where the previous pump was. How would you fix the hole?

Frame up and put drywall? Or plaster?

How large are the holes usually from an air source?

Well.. I know nothing about that. How do I know?

The hole should be around 7cm unless it's made with a chainsaw. Cut out a square about 10cm, insert a small piece of wood and secure it in the drywall, and then a piece of drywall that fits the hole. Spackle/tape and paint.

The hole is likely around 7cm if it hasn't been made with a chainsaw. Cut out a square about 10cm and insert a small piece of wood and fasten it to the plaster and then a piece of plaster that fits the hole. Fill/tape and paint.

Can I fasten to the plaster with glue?

This is how it looks

A bit difficult for us to know if it's plaster on wooden studs, concrete, plastered plank frame, or something else. You might need to come back with pictures of how the holes look.

Look in the hole.
