10K U-Shape Window AC

The U-shape is the most-requested AC design in NYC and we get why: at 42 dB it's quieter than a refrigerator, the window closes around the U-shaped saddle so you can open/close it normally (security + street noise), and it draws 35% less power than equivalent fixed-speed units. The shape works only in double-hung windows where the sash can close around a 5-inch saddle — we verify clearance during booking.

Highlights

  • 42 dB at low speed — quieter than a library
  • Window closes over the saddle for security and street noise
  • Inverter — Energy Star Most Efficient (2024 list)
  • 35% lower energy draw than equivalent fixed-speed units

Maintenance during your rental

Nothing required from you, but two small tasks keep efficiency at spec:

  1. Rinse or vacuum the front filter every 4–6 weeks (slides out from the front). Takes about 60 seconds.
  2. If you hear a new rattle or the cooling weakens, text us — we’ll swap the unit at no charge under the warranty pass-through.
