    • I have never heard of Premium Home Source, tell me about your company.
      • Premium Home Source is a family-owned company that is solely focused to serve our customers in the most honest and transparent manner. We first understood the importance of high quality appliances when we bought and built our first home in 2017. When we found it almost impossible to source high quality and affordable home goods and appliances, we knew we weren't the only ones. Understanding the pain points of sourcing quality home goods first hand, we sought out to make this process transparent, price efficient and seamless for every homeowner, contractor, landlord and property manager.

    • Are these items refurbished? Used?
      • All items we sell are Brand New - we will never ship you a refurbished or used item.
    • How does shipping work?
      • The shipping carrier will deliver your order curbside. The carrier cannot deliver into your home, garage, kitchen or elsewhere. For orders with large appliances (ex: range or refrigerator), the freight company will call you ahead of time to arrange a date and time to deliver the items.
