AerioQ for a home office that gets warm in the afternoon?

A second one for a 10×10 office is not overkill at all. Mine is in a slightly bigger room and it still takes a while to knock down the afternoon heat when the sun is coming in. I’d rather have it running on low than sweat through my meetings.

Mine couldn’t keep my office comfortable once the sun hit, and that room’s about the same size. It was fine in the morning, then just kind of blew around warm air by 3pm. So I’d say try it before buying a second one, because for me it wasn’t enough.

Adding a second one for a 10×10 office is fine if you just want to take the edge off. Just don’t expect it to fight real afternoon sun. I’d rather have a fan and closed blinds doing most of the work than relying on a wall unit for that.

Mine barely did anything once the sun hit that window.

I have one in my office and it handles the afternoon sun better than I expected. My setup is a bit different since I keep a blackout curtain pulled on the west side until around 3pm, then let the light in after the worst heat passes. The AerioQ stays on low the whole time and the room never really gets uncomfortable. Not saying it beats a real AC, but for a small room it does the job without me thinking about it. The one thing I noticed is that placement matters more than I figured. Mine sits higher on the wall and angled toward where I actually sit, which made a bigger difference than any setting. If you already like the one in the bedroom, a second unit for the office seems reasonable to me. I would just mess with where you mount it before deciding it can’t keep up.

I keep mine on a desk near the window rather than wall mounted, and for a 10×10 room it does okay if I turn it on before the room gets hot. If I wait until the afternoon sun has already warmed everything up, it takes a while to catch up and never really feels cold, just less stuffy. So timing makes a bigger difference than I expected. I usually just run it on the lower setting for an hour or so and that’s enough for me, but I’m not trying to get the room chilly, just comfortable enough to work. For a second unit I’d probably try it in the office first before deciding, since you already know how it behaves at night. Afternoon heat is just a different thing honestly.
