Running costest.

~$115/year

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 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.
