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.

  • R-32 refrigerant and strong dehumidification (71 pints/day)
  • Lower price than the inverter Duo and NEX models

What to watch

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.
