Appliance Delivery 1, Basic Installation 2, and Haul-Away 3 Information for Refrigerators, Washers, Electric Dryers, and Electric Ranges

The home delivery service includes basic installation to set up your new appliance, as well as haul-away of your old appliance. Parts and accessories required for basic installation are included. Member will receive a call, email, and/or text from a service representative to confirm appliance installation requirements and limitations. Before placing an order, please confirm that the contact information in Your Account is correct (address, email, phone) to ensure a smoother delivery process. Member must be at home during the scheduled delivery time frame.

1. Delivery: Delivery and Basic Installation are available in limited locations (not all zip codes covered) and only in the continental United States. Delivery is not available in Alaska, Hawaii, Puerto Rico and other U.S. territories or for APO or FPO addresses. Additional service fees for rescheduled delivery will apply if delivery is attempted and Member is not home or does not answer.

2. Basic Installation: The delivery and installation teams are NOT authorized to perform any modifications to your home, such as carpentry, plumbing, gas or electrical work. Additional fees will apply for any installation work that exceeds the included Basic Installation service. Basic Installation may be unavailable in some locations depending on local, state, or industry codes and standards. During your home delivery appointment, the delivery and/or installation team(s) will be able to determine if any additional work and/or permits are required that exceed the Basic Installation, and you will be given a quote before agreeing to additional installation work and fees. You will be responsible for direct payment to the installer for any work exceeding the Basic Installation.

3. Haul-away: The delivery service includes haul away of your old appliance, provided it has been uninstalled prior to delivery. Complex deliveries, including dishwashers, gas ranges, gas dryers, and over the range microwaves, may require separate delivery and installation appointments. The delivery team will not uninstall or remove existing appliances. Haul away will be provided by a licensed installation contractor during the second appointment, not the delivery provider.

For your safety, the delivery team CANNOT:

  • Remove their shoes. They will act with care to protect the home and merchandise
  • Alter property to complete a delivery except for simple door removal
  • Modify existing cabinets or HVAC equipment, including alterations such as cutting into existing cabinets, walls, counter tops, etc.
  • Relocate or reconnect used appliances to home utilities.
  • Convert gas or propane lines
  • Lift or hoist appliances over objects or through windows to complete a delivery.
  • Work with or touch exposed wires, rusted or corroded shut-off valves and copper valves
  • Update home to local code. If the connection points are not up to date to local code, the customer will need to hire a licensed plumber or electrician to bring the home up to code.
  • Uninstall or relocate built- in appliances. Will haul away only if uninstalled before delivery and if a haul-away service was purchased with delivery. NOTE: Built-in refrigerators cannot be hauled away.

Comparing with my 22-year old Kenmore, it's noisier and the wash cycles seem to take a bit longer.

reply from LG CareQ

We truly appreciate your comparison with your previous 22-year-old Kenmore, and we completely understand that moving to a modern LG Front Load Washer can feel like a big change! Today’s eco-friendly washers are designed to operate a bit differently, using longer, ultra-gentle tumbling and high-speed spin cycles to thoroughly clean your fabrics while helping save water and energy. We understand that this may also result in differences in noise and cycle duration compared to older models, especially one you’ve been familiar with for so many years. Your feedback is very valuable as it helps us understand how our products are experienced in everyday use. If the noise ever feels more like a heavy vibration or unusual sound rather than normal operation, we’re always here to help check simple setup items such as leveling or installation to ensure optimal performance. If you ever need assistance, our LG Care team is happy to help at 1-888-542-2623, or via WhatsApp, live chat, or email at https://www.lg.com/ca_en/support/contact-us/. Thank you again for sharing your thoughts and for choosing LG—we truly appreciate your support.
