Hi guys,

So my next door neighbor relocated their AC compressor unit from their backyard to sideyard, facing our house.
It's about 4 feet to the wooden fence (which is about 7' high) that is in between their property and ours.
I attached an drawing to illustrate what the situation looks like.

I'm wondering, how much of difference does it make, in terms of the noise level, between the original location and the new location of the AC?
I mean, if I ask them to move the AC back, how much would it help to reduce the noise level?

Based on the diagram, moving the unit back to the original location most likely would not reduce the noise level that much.
At least you have a 7' high fence! I would use mass loaded vinyl and staple to the fence.
Cover from top of fence to ground and the length would be entire line of sight of the unit. which could mean most of the run.

Thanks a lot, Randy!

It's very helpful to know that it won't make that much of difference because that could save me some interesting arguments with my neighbor.

Regards to the noise level from the AC, actually rooms on the first floor is not that bad.
Barely I can hear the AC if I close all my windows in our family room.
I guess it's because that 7' wood fence helps quite a bit in blocking the noise.

It's more of an issue for one of the rooms that is on the 2nd floor, directly above the family room.
I can see their AC in full sight from the window in that room so I guess that also means sound could travel to this room without any resistance.

So anything good to put up for this 2nd floor room?
We already installed shutters to all the window in that room. But they don't help that much.

I heard there is a drywall product called QuietRock that could help a lot.
But that's a relative large project to do to our brand new house.
Is there anything that requires less effort we could try before the QuietRock?

Don't waste your time with quiet rock, you need to address the weak spot first and for the second story it would be secondary window treatments first.

You are correct the fence will not help with second story noise issue.

Here is a link to show you how to address the windows.

or install a second set of operable windows in the same frame with the maximum gap you can achieve.

We already have shutter installed on that window frame so it looks like we can't install any additional window treatment unless we take down the shutter.

yes you would most likely have to remove the shutters.
