Hot/Cold Spots in Shed?

[Apoxbrew]

So I'm considering putting a smallish shed out back... not for brewing but for fermenting and storing.

I'm curious how one would add A/C and Heat to such a shed in a way that wouldn't cause hot/cold spots near the source of said hot/cold?

I've been thinking about it and am not quite sure how to diffuse the temperature evenly (as possible) throughout the shed so I could utilize all the space.

Would love any input y'all have. Thanks!

just put a small fan in the room and circulate the air

You can test the results by having 2 thermometers and move them around the room and check for temp differences
