Will it cool your room?
This is undersized for your 450 sq ft room. It would run flat out and struggle to keep up.
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.

Power while cooling: From the maximum cooling draw its retailer lists for this exact model. An hour's cost is at that draw and the US average electricity price of 18.44¢/kWh (U.S. Energy Information Administration, Electric Power Monthly Table 5.6.A (residential average, May 2026)). The compressor cycles once the room is cool, so most hours cost less.

- Uses R-32 (GWP 675), the low-GWP class new US residential equipment moved to.
What to watch
- At 57 dB(A) it is louder than 30 of the 32 other portables we list that publish a noise figure.
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.
