Will it fit your wall sleeve?
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

Installation & the rules that apply
This 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.

Common questions about the TCL 10,000 BTU Through-the-Wall Air Conditioner - Cool Only 115V
- What size room does the TCL 10,000 BTU Through-the-Wall Air Conditioner - Cool Only 115V cool?
- It is rated to cool a room up to 450 sq ft (10,000 BTU · 2.9 kW).
- Do I need a professional to install the TCL 10,000 BTU Through-the-Wall Air Conditioner - Cool Only 115V?
- Not to replace a unit, but usually yes for a new opening. Sliding it into an existing wall sleeve it fits is a job you can do yourself (it is heavy, so plan on two people), with no refrigerant work. A new installation means cutting an opening through an exterior wall and fitting a sleeve, which is contractor work and usually needs a building permit. It runs on 115 volts, the standard household supply.
