Wall studs are used to support walls, and they’re usually 16 inches apart.
Once you’ve picked a location, you’ll need to mark the studs, so you know where you’ll be able to cut through the drywall later.
You want to keep your number of walls to be removed to a minimum.
You have two choices here:
- Use a stud finder to find the stud holes precisely.
- When you tap on the wall, you’ll see a point where the sound becomes solid. Next, hammer a thin penny into the wall to verify where the best spot is if you hit a stud, good. If not, try it again.
Once you’ve found 3-4 studs, mark them on the wall with an ‘X’ using a pencil.
Measure the width of your air conditioning unit and then mark the wall where the stud was located.
You should get an installation manual and template for your air conditioner to trace its outline on the wall.
If not, use the sleeve (bracelet) for this purpose.
Make sure you set the sleeve or guide paper correctly so that you can cut within the fewest numbers of studs.
