How to Install an A/C Bracket

A window air conditioning unit can get a room cooled down quickly on a hot day in the Delaware Valley. Setting up the window unit requires you to know how to install an A/C bracket. The bracket mounts on the exterior window sill. You need to select a bracket with a weight-bearing capacity appropriate for your A/C window unit.

Tools NecessaryHow to Install an A/C Bracket

In addition to these tools, it’s always a good idea to wear safety glasses whenever using a power drill.

  • Measuring tape
  • Power drill
  • Small adjustable wrench
  • Small level

How to Install an A/C Bracket Steps

  1. Lift the air conditioner unit one side at a time to see if its weight is centered or off-center to the left or right.
  2. Measure the width of the exterior window sill.
  3. Divide this measurement in half so that you can mark the center point on the sill.
    1. If A/C has centered weight, then use the mark in the middle.
    2. If A/C is heavier on its right or left side, make a second mark 3 inches to the right or left of the first center mark.
  4. Find the mounting block that came with the bracket kit.
  5. Drill a hole where you marked on the window sill.
  6. Attach the block with a screw.
  7. Position the next block from the kit on the mounting block.
  8. Attach the top bracket bar with screws to the sill blocks.
    1. Do not tighten these screws completely yet.
  9. Take the bottom mounting bracket and attach it with bolts loosely to the top bracket.
  10. Adjust the brackets using a level on the top bracket.
    1. After finding the level point, angle the bracket very slightly downward so that water will drip away from the house.
  11. Once the bracket is positioned correctly, tighten all screws and bolts.
  12. Mount the A/C unit on the bracket according to the manufacturer’s directions.
