  • Haul Away: We will haul away your old appliance at the time of delivery for basic hookup items (refrigerators, freezers, or electric dryers-ranges-all in ones) or at time of installation if a secondary appointment is required (dishwashers, gas appliances, built-in appliances such as microwaves, wall ovens, cooktops).
    • Note: Haul Away is available, it is on a one-for-one, like item, basis. If Costco does not offer installation in your area for wall ovens, dishwashers, cooktops, or over the range microwaves and you want our team to haul away, they should beĀ  professionally uninstalled and ready for pickup prior to delivery.
  • Safety First: Our teams are required to install anti-tip brackets where applicable at no extra cost.
