Supply voltage, plug, cooling power, cooling current, refrigerant and warranty are from Sylvane's published specifications for this exact configuration, checked Oct 18, 2026.
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.
What is good
- At $330 it undercuts 17 of the 19 other 10,000-11,000 BTU window units we list with a live price.
- Uses R-32 (GWP 675), the low-GWP class new US residential equipment moved to.
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.
Self-fit, no pro needed
