Why do heat pumps have to be off the ground?

So when a manufacturer instructs us to get the heat pump above the anticipated snow level and the heat pump is 8 inches off of the ground, that is enough to protect the unit from over 8 feet of snow accumulation if there is nowhere for the snow melt to drain below the unit base.

How high should my AC unit be off the ground?

In a 10 feet high room, a split type AC should be installed at 7 -8 feet for the best cooling performance. For a window type AC, the best height is 3-4 feet from the floor. If you are fixing the AC very close to the wall or in an airtight room it will trip due to high head pressure, as heat dissipation can't happen.

Where should a heat pump be placed?

For best performance for heating, locate the outdoor unit in the warmest location, e.g. on a north or west facing wall (and vice versa for cooling). Heat pumps are most efficient when the temperature differential between outdoor and indoor temperatures is at its lowest.

How high should a heat pump be installed above the snow line?

Let it snow—but not on your outdoor unit!

Can heat pumps be installed anywhere?

The fact that ground source heat pumps work by extracting solar energy stored in the ground means they can be installed virtually anywhere.

What happens if heat pump not level?

Can you build a deck over a heat pump?

It is not. A deck would be a lot more than an "obstruction". To operate correctly, the area the unit is in needs to be ventilated well so that heat doesn't build up in the area.
