Many have no cooling at all. Others have window shaker ACs only in bedrooms (which aren’t practical to use window heat pumps as a replacement for radiators since the heating balance would be terrible with the rest of the house and the air leakage around a window unit is really bad when the inside/outside delta-T is 60+°F in winter [versus ~15°F in summer])
