- Keep Clear of Weeds and Dirt
- Possible Wall Vibration
- Look and Feel
- Needs to be Properly Mounted
The main advantage of a wall-mounted unit is keeping snow off as well as animals away.
Areas with heavy snowfall during the winter often use wall mounts since a unit buried in the snow will have problems operating.
Dirt and weeds can also get in the way of a mini split working properly with a unit higher off the ground not having this problem.
The downside is possible noise vibrations along with the look needing to match a home.
A unit properly mounted on a solid wall should have minimal noise.
The unit will need to be well mounted on studs or bolted into a brick or cement wall.
