We are pretty excited to bring you our latest build. In our backyard, we have an old ugly AC unit. It’s an eye sore like most people’s outside AC units!

So we decided to hide it by building a fence around the AC unit. Here's how we did it:

Here’s what we had to work with... a pitiful bush and a hunk of metal on a small concrete slab.

With a little research, we realized we would need certain spacing in order to not suffocate the unit and leave room for breathability.

We surmised that we needed 54 inches total of an air gap.

1. Plan the design

We went to the drawing board and came up with this simple design.

2. Build the fence with 2x4s

We started with four 2x4 posts evenly spaced around the unit.

Then we ran 2x4 on the top and bottom to connect the posts.

3. Screw in 1x2 slats

Lastly, we screwed in the 1x2 slats. We wanted to use slats to aid in the breathability of the unit.

Leaving a gap between the AC unit and fence

It may look tight but we left enough room! 💪😁

Tips: We chose not to cement the posts in case of maintenance or replacement of the unit. Of course, we used pressure-treated wood.

    We had this done for our AC unit by our fence company on 2 sides only. One of the open sides faces the house and the second faces the fence so open for maintenance and air flow!
