14,000 BTU, 9,000 SACC Smart Wi-Fi Portable Air Conditioner (RAC-PD1411CWU)

We use Toshiba 14,000 BTU units, with insulated HVAC piping for the exhaust, connected and then taped with thermal tape to prevent leaks. The HVAC piping goes into the ceiling tile, and exhaust out the side of the building. We have hot spares in case one dies. Bonus points, put in some sound deadening material in the server room if the are people in adjacent offices :) A lot of the times it's the exhaust heat that kills the components., the OEM exhaust piping is garbage - usually very hot to the touch. The insulated piping is a world of difference. Also important to drain the condensation and clean the filters monthly.

No but I just bought the Toshiba one at home depot and it works marvels

Me and my wife got a Toshiba one that worked amazing when we were down in Oceanside. And even better once we moved to a drier climate. We got it from home depot and it was ~$400. Can't remember the exact model.

I lived on the 4th floor in Irvine without an AC for 4 years. You’ll need a portable AC but make sure you get one thats good. The Toshiba one I had was good and made the bedroom pretty chilly at night. Just make sure to drain it every night because it can be pretty humid in Irvine.

The problem is not the cycling, is that you have a cheap ass AC. Get a solid sturdy surface to place them, no carpet. I suggest Toshiba AC are very nice
