A room up to 450 sq ft. LG rates it for 500 sq ft, the room its 14,000 BTU box rating would suit, but a portable is sized by its SACC, which counts the heat its exhaust hose and casing put back into the room, and ENERGY STAR's sizing chart gives the 10,000 BTU (SACC) the Department of Energy certifies it at a room up to 450 sq ft.

This is undersized for your 700 sq ft room. It would run flat out and struggle to keep up.

Running cost

The portable units we list are not ENERGY STAR certified, and portables are rated on a different (SACC) basis that is not comparable to the nameplate-BTU estimate the window figure uses, so there is no honest dollar figure to show here. As a category, portables (single-hose models especially) usually run less efficiently than a comparable window unit.

Installation & the rules that apply

This is a portable monobloc. The most regulation-light option by far. No EPA Section 608 certified technician is needed because the refrigerant circuit is factory-sealed and never opened, no building or mechanical permit is triggered since nothing is fixed to the structure, and a landlord has little ground to refuse a unit that leaves no permanent alteration. The real constraints are your lease or HOA rules on how the window kit looks from outside, and noise to neighbours.
