What size room does the Perfect Aire 10,000 BTU Through-The-Wall Air Conditioner 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 Perfect Aire 10,000 BTU Through-The-Wall Air Conditioner?

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.

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.
