Question 1

How fast can you install?

Accepted Answer

Most days, same-day or next-day in all five boroughs. Tap Check availability on the home page and we'll show you the earliest open slot for your zip in real time.

Question 2

How long does the install take?

Accepted Answer

Most window installs are done in 15 minutes. PTAC swaps take 20–30. We text 30 minutes before arrival so you don't sit around.

Question 3

What if my building requires a Certificate of Insurance (COI)?

Accepted Answer

We issue COIs in under an hour during business hours for $19. If your building is in our database, the form pre-fills. We email it to your building's management with read receipt and copy you.

Question 4

Can you install in a 5th-floor walk-up?

Accepted Answer

Yes — we add a small transport fee ($20/$40/$60) depending on flights so we can pay our installers fairly. The fee is shown upfront, never sprung at checkout.

Question 5

How do I know what BTU I need?

Accepted Answer

Tap the BTU calculator — tell us your room's square footage and we'll recommend two units. Or use the rough rule: 20 BTU per square foot, +10% for high ceilings, +4,000 for kitchens.

Question 6

What if my windows are casement (crank-open) or sliders?

Accepted Answer

Standard window ACs won't fit — but our Portable 12K is built for exactly this. It vents through any window type with a universal kit, and rolls between rooms.
