Will it cool your room?
This has more cooling than your 150 sq ft room needs. It can short-cycle and leave the air cool but humid.
Estimated from ENERGY STAR's published annual energy use at about 750 hours of cooling a year (the DOE test standard) 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)). A standardized figure for comparison; your real cost depends on how much you run it, your local rate and your climate.
Local rates vary widely (about 15¢/kWh in Florida to 33¢ in California), and hotter regions run their AC more hours, so your real cost differs.

Installation & the rules that apply
This is a window unit. No EPA Section 608 technician is needed: the refrigerant circuit is factory-sealed and never opened. A plug-in window unit needs no permit, so the friction is with your building rather than the government. Many HOAs restrict window units on appearance grounds, though an HOA regulating how you mount one stands on much firmer ground than one banning cooling outright. Landlords can set conditions, and the falling hazard is taken seriously: New York City, for instance, requires window units to be supported by brackets or mounting rails, and many building insurers and HOAs now require a bracket regardless of city.
