This ships by freight truck on a pallet, not by a parcel carrier. The carrier calls ahead to set a delivery window, and an adult 18 or older must be there to receive, inspect and sign for it.

The driver brings it to the back of the truck, or lowers it to the ground with liftgate service. They don’t bring it inside, so plan for a pallet jack or two people to move it from the curb.

What to have ready on delivery day

  • Count every piece against the delivery receipt.
  • Check every side for crushed corners, torn wrap, punctures, water stains or a tipped unit.
  • Photograph the freight on the truck before it’s moved.
  • If you see any damage, even cosmetic, write “DAMAGED” and what you see on the receipt before you sign.

Your shipping email has the exact instructions for your order. Questions at the door? Call us at (888) 307-5030.

How to inspect and sign for freight

Keep all the packaging, photograph the damage and the packaging, and tell us within 5 business days of delivery. Reply to your shipping email with the photos or call (888) 307-5030.

If the driver won’t wait while you inspect, write “Received – pending inspection. Driver would not wait.” with the date and time on the receipt, then inspect right away and report any damage within 24 hours.

Reporting damage after delivery

Book your installer only after the carrier gives you a firm delivery appointment. Freight dates can move, and installer trips lost to a late truck aren’t reimbursable.
