Toshiba - 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.

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 am using a Toshiba and a Midea in the house. Toshiba must be a subsidiary of Midea because the Midea Smart Home app can recognize and control the Toshiba portable unit as well. I use the app to control the units remotely.

I have the Toshiba one of these (Just a rebadged Midea, even the app for it is Midea), barely made it a year... compressor went into a "death worble"
