my home office is too hot. Help!!

radman2020

I have a small home office, maybe 100 sq feet. It gets very hot because I have a good amount of computer equipment in it. I have one air conditioning duct into the room without a return. The room is always hot when the rest of the house is cool. I don't want to crank up the ac for the whole house just for this room. Plus, it is hot when the rest of the house is not being cooled... like in the winter. I can't put a small ac unit in the window because this is right next to my front door and would be unsightly. A portable unit still has to be vented and would be a security risk. I could cut a hole through the wall to get to the garage but that would just heat my garage way up and would drip water all over.I put in a fan but it just blows hot air. All the basement ducting leading to the room is covered because the basement is finished. I did try a swamp cooler... no help...made the room warmer.

any suggestions?

thx

A ductless mini-split.

Outside unit can go on a side wall, and is usually quite compact. Refrigerant lines require a hole no larger than 3", you can run ithem through garage.
