Whynter Portable Air Conditioner 14,000 BTU & Heater with Dual Hose Dehumidifier & Cooling Fan for 500 Sq Ft Rooms, Includes AC Unit Window Kit, ARC-14SH (9,200 SACC)

https://a.co/d/03NULm88 Currently 61F in my room. Keeps my room cool in summer and toasty in winter, sometimes too toasty. Buy a condensation pump to hook up to the drain plug and feed it out your window so you don’t gotta worry about emptying it. Might have to run the line into a bucket during winter time if it gets below freezing in winter, but it takes a week for mine to fill a 1g bucket up in winter so not a big deal

I got this one 9yrs ago and it’s still running great. You could probably do this unit or one like it in that window. https://a.co/d/02rsRE1m
