Thru Wall Air Conditioners
When you need an efficient, permanent cooling solution for a single space, commercial and industrial through-the-wall air conditioners are a great option. If a room gets a lot of direct sunlight or is full of heat-producing equipment, through-the-wall air conditioners can supplement the central HVAC system. They can also be used standalone and are especially common in hotel rooms, conference rooms, offices, and apartments.
Through-the-wall air conditioners are unobtrusive, easy to use, and surprisingly easy to install. They're affordable and can last a decade with proper maintenance. While window units have the advantage of being removable, some people prefer the through-the-wall unit simply because you're not blocking your view. Aside from the temporary vs. permanent consideration, it might also depend on what your space is used for and what is on the other side of the wall.
