8K Window AC

Our most popular small-room unit — inverter-driven, eerily quiet, and slim enough to fit standard NYC double-hung windows. Ideal for studios, single bedrooms, and home offices up to 350 square feet. Smart eco mode adjusts compressor speed continuously rather than cycling on and off, which is why the room temperature stays within ±1°F of your setpoint instead of swinging 5–7°F like older units.

Highlights

  • Inverter compressor — 30% more efficient than fixed-speed
  • Sleeps under 51 dB — quieter than a normal conversation
  • Smart Wi-Fi + Alexa / Google Assistant
  • Energy Star certified

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.
