12,000 BTUEnergy StarWindow

12K Window AC

For pre-war rooms with high ceilings, south-facing windows, or that one open-plan studio where the kitchen and bedroom are the same space. Cools 12,000 BTU/hr while drawing under 1,000W in eco mode. A 12K unit on a typical NYC circuit pulls about 9 amps — safely within the 15-amp limit of a standard residential outlet.

Highlights

  • Inverter, Energy Star, Wi-Fi enabled
  • Handles south-facing sun exposure and high ceilings
  • 4-way airflow louvers (manual + automatic swing)
  • Sleep mode auto-warms 2°F over four hours

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.
