The short answer
Heat pumps that run in winter need the outdoor unit above expected snow depth with room for defrost water to drain. Ground stands lift it without loading the wall, wall brackets save ground space but can carry vibration into the house, and pads are the simplest choice where snow isn't an issue.
Side by side
| Wall bracket | Ground stand | Pad | |
|---|---|---|---|
| Snow clearance | High | Medium-high | Low |
| Vibration into the house | Possible; use rubber pads | None | None |
| Install | Lag into framing or masonry | Level ground | Level, compacted base |
Options we cover
Brackets such as the SMOQIO wall bracket; stands such as the WeCooper ground stand; pads such as the DiversiTech 36 x 36 in pad.
SafetyCheck the load rating against the condenser's weight, and anchor brackets into studs or masonry, never siding alone.

Questions readers ask
Is it better to wall mount a mini-split condenser?
It keeps the unit clear of snow and saves space, but can transmit vibration; ground stands avoid that.
How high should the outdoor unit be?
Above your typical snow depth, with clear space below for defrost water to drain.
