Minisplit mounting brackets
Hello–thanks to reading a lot of posts here, I am installing two mini-split units for a shop I’m building. I live in Wisconsin and I want to use the wall mounting brackets to keep the outdoor condensers off the ground. I was thinking that I could hang the units from some horizontal boards attached to posts supporting a deck.
This got me thinking. Don’t these wall brackets put the units too close to an obstruction for drawing in air? If I have enough 2x material to support the brackets it’ll block about 50% of the intake area.
Maybe other units don’t require as much space, but mine want 12”. I’m looking for an appropriate bracket, but I’d like to hear other ideas.

The proper type of brackets allows at least 12" space from the wall, usually a lot more.
I'll keep looking. With a condenser about 14'' deep, I'm having trouble finding one.
You can assemble a mount from strut parts to get what you need. Strut is commonly available at commercial electrical and mechanical supply houses as well as the box stores (usually in the electrical section near conduit). Get some galvanized strut, some angle brackets, some spring nuts (cone nuts are better if they have them), and some bolts and washers and assemble what you need.
It helps to paint the cut ends of the strut pieces to protect them from rust.

BC,
Adjustable mini-split mounting brackets seem to be in the $70 range. Probably not worth fiddling around making your own.
One thing to watch for. Never mount outdoor units to wood structure that can carry the vibration into the building. They don't make a lot of noise, but you will hear it and will be annoying.
Usually the best bet is ground mount or bracket off concrete foundation.
