15K Window AC

When 12K isn't enough — converted lofts, double-height brownstones, top-floor walk-ups in July. We install with a heavy-duty bracket; the LL57 safety bar add-on is included for households with children age 10 or younger. The 91-lb unit is at the edge of what one installer can handle safely, so we always send two-person crews for 15K installs above the 4th floor.

Highlights

  • Powerful enough for converted lofts & double-height rooms
  • Inverter compressor — quieter at high BTU than competing fixed-speed 15Ks
  • Heavy-duty bracket included (rated to 250 lb)
  • Compatible with NYC LL57 safety bar (included when child ≤10)

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.
