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)
Will this fit my room?
Add 10% if your room has 9-ft+ ceilings, south/west sun exposure, or kitchen heat load. Subtract 10% if you keep blackout curtains closed.
What it'll cost to run
Based on ConEd’s ~$0.32/kWh residential summer rate and average NYC use patterns. Inverter units track lower; sun-facing rooms track higher.
How loud is it?
Moderate. About background office noise (60 dB)

Maintenance during your rental
Nothing required from you, but two small tasks keep efficiency at spec:
- Rinse or vacuum the front filter every 4–6 weeks (slides out from the front). Takes about 60 seconds.
- 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.
