TCL says its through-the-wall units fit standard 26-inch sleeves: its manual asks for a sleeve (not supplied by TCL) at least 26 inches wide and about 15¾ inches high, and TCL strongly recommends insulating the gap if the sleeve is slightly larger. A sleeve shallower than 20 inches still works, but the unit then sits further out into the room. Source: TCL: choosing a wall sleeve
Every through-the-wall AC and PTAC by the sleeve it fitsThis is a through-the-wall air conditioner. It sits in a sleeve built into an exterior wall, so the window-unit mounting and bracket rules do not apply to it. Swapping it into an existing sleeve is a like-for-like replacement; cutting a new opening changes the building's exterior wall, which usually needs a building permit and, in a condo, co-op or historic building, approval first.
