The rental kit had a faulty gauge but I was able to borrow one to finish install. I contacted customer support and they were very helpful and gave me full refund upon my returning of the kit.

The product and Della were 5 star second unit I’ve bought from them. The first unit I bought shipped UPS. Shipping went great this last unit I bought shipped LTL Central Transport. They had unit at there hub and would not bring it to my house and would not call me. Worst shipping I’ve ever had

Thank you for your continued support and for choosing DELLA again. We're thrilled to hear you've had a great experience with our products. We're very sorry to hear about the delivery experience with the second order. Shipping methods may vary depending on the size and type of product. Larger items are typically shipped via LTL freight, and the carrier is generally expected to contact the customer to schedule delivery and obtain a signature upon arrival. We sincerely apologize that this did not happen in your case. We appreciate you bringing this to our attention, and we'll share your feedback with the shipping carrier to help improve future deliveries. Thank you again for your support and understanding.

I have mixed feelings about this purchase. The replacement PCB was the correct part for my DELLA 12,000 BTU mini-split outdoor unit, and after installing it, it fixed the problem. The part itself worked as expected, and I appreciate that DELLA made the correct replacement available. My disappointment is with the warranty policy. I was told that the part would have been covered 100% under DELLA’s lifetime parts warranty if I had registered the product within the first 100 days of purchase. Unfortunately, I was not aware of the registration requirement. I’ve owned mini-split systems before that lasted 10+ years without ever needing repairs or replacement parts, so I didn’t expect that I would need to register a new unit simply to receive warranty coverage. The unit was less than two years old when the PCB failed. When I contacted customer service, I was told that because I had not registered the product within the required timeframe, they could not provide the replacement part under warranty and I had to purchase it at full price. I understand that warranty terms are established by the manufacturer, and I take responsibility for not registering the unit. However, I feel that if DELLA is willing to offer a lifetime warranty on parts, they should stand behind their product even if the customer did not complete a registration process. A PCB failure on a unit that is less than two years old is disappointing, and having to pay full price for the replacement makes the experience even more frustrating. Overall, I’m glad the replacement PCB was correct and fixed the problem, but I believe DELLA could do better when it comes to supporting customers and standing behind the reliability of their products.

When dealing with the company, the customer service to the technicians that I spoke to were all very helpful not only helping with the problem, but making sure the right part was ordered.
