What’s Included
  • Delivery & Basic Hookup: Professional delivery and connection to existing compatible utilities are included in the price for most members. Confirm by entering your ZIP code and reviewing "Services" at checkout.
  • 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 be  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.
  • Additional, in-depth information to be prepared for a successful delivery day can be found here: Delivery and Installation Guidelines - Appliances


 

Member Readiness & Requirements
  • Utilities: Existing electrical outlets, water shut-offs, and gas valves must be accessible and within 3 feet of the appliance but not through walls, floors or cabinets.  Must be in good operational condition.
  • No Home Modifications: Our teams are not licensed carpenters, plumbers, or electricians. We cannot modify cabinetry, flooring, countertops, walls or baseboards.
  • Accessibility: An adult (18+) must be present. The delivery path (both inside and out) must be clear and accessible without risk to property or personnel.
  • Propane (LP) Disclaimer: We connect to Natural Gas only. We cannot connect to Propane (LP) lines, even if a conversion kit is provided.
  • Additional, in-depth information to be prepared for a successful delivery day can be found here: Delivery and Installation Guidelines - Appliances


 

Scheduling & Logistics
  • Notification: You will receive a 2-hour window via phone/SMS between 6–9 PM local time the evening before your scheduled delivery. If a secondary installation appointment is required (dishwasher, gas and built-in appliances) you will also be contacted by your installer with a 4-hour window and then a 30-minute call prior to arriving at your home.
  • Timeline: Delivery must be accepted within 10 days of contact to avoid order cancellation.
  • Service Area: We typically deliver within a 50-mile radius of any Costco warehouse. Please enter your delivery location zip code on the homepage or product page to verify availability for your location. Delivery to AK, HI, and PR incur additional shipping fees.

If a disposal, recycling or e-waste fee or tax is applicable in your state, this will be applied to your order and collected at checkout.

⚠️ Installation Appointments: Installation is performed by a specialized contractor and may require a secondary appointment separate from delivery. Code upgrades (air gap, GFCI, countertop modifications, etc.) not included and additional site-specific work can be quoted separately at the time of installation. If the appliance has been disconnected prior to delivery, haul away will occur at time of delivery. If not, haul away will occur during the installation appointment. Haul away is on a one-for-one, like item, basis.
