Will it cool your room?
This unit's cooling matches a 59 m² room, though its rated output is a little under what this room usually needs, so it may run flat out on the hottest days. Set your room size to check the fit for your space.
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.
At a glance
Best for renters and rooms where you cannot install a fixed unit.
This is a window unit. No F-gas installer needed (sealed unit), but the regulatory friction is about the window and facade, not refrigerant. European tilt-and-turn windows physically do not accommodate them, many cities restrict anything that alters the external appearance, heritage and historic-centre rules often prohibit a box hanging out of a facade, and a landlord or building association can refuse it on safety (falling) and appearance grounds. Common and lightly regulated in the US, often effectively banned or impractical in much of Europe.
