Ruby G was a great customer service representative she helped get a part expedited for a one of our customers who was elderly. She was patient and courteous and did her job very well. Highly recommend.

Customer service seems good. The product appears to be good so far. Only have had it installed for 2 days. The up/down flap doesn't close all the way on the left side. I will call tech support to see how to resolve that problem. The other problem I have is I could not get the system into service mode to adjust the temperature offset override. I called tech support and was told the newer models do not allow you to adjust the temperature offset and they are preprogrammed for a 4 to 7 degree offset. My unit has a 4 to 5 degree offset. Set to 77 it cools to 72 or 73. I also enabled the "follow me" on the remote and still have the same temperature offset. I find this unacceptable. I can understand 1 or 2 degrees but 5 degrees is ridiculous. If you want 73 degrees you have to set it for 78. The customer should be able to adjust the offset so the setting matches the room temperature. I was told the manufacturer is working on a board replacement to remedy this issue. I would feel better about my purchase if this issue can be resolved ASAP

Answered phone in a reasonable time. I could communicate with the rep. The rep was able to quickly resolve my issues.

Having a problem with controlling the temperature. We set it at 77 and the unit cooled off to 72 degrees. Fella is going to send a new sensor to see if that fixes the problem.

Thank you for bringing this to our attention, and we sincerely apologize for the inconvenience with the issue. Please feel free to install the new sensor once it arrives, and don't hesitate to reach out if you continue to experience any problems or need further assistance.

I had received a damaged shipment and called to report it. Hector was courteous and took the information and ordered a replacement shipped. I received a call back that the replacement had been ordered. I explained that I had scheduled install and this delay was an inconvenience. He said he would see what he could do to expedite the process. The original equipment took about 9 days to receive and was received damaged on Wednesday which is when I called to report it. The replacement is scheduled to be received tomorrow which is Saturday. That is 3 days. I would say that is excellent customer service and I will be very satisfied if the replacement is received undamaged.

I had a few issues with my order, but DELLA support handled everything well. My mini split arrived with shipping damage to the outdoor unit. The box was pretty beat up, and the condenser fins/frame had some damage from transportation. I contacted DELLA support through live chat, sent them pictures, and they helped me work through it. They confirmed I could inspect the unit without affecting the warranty, and after I finished the install, the unit powered on and worked great. It blows very cold air and seems to be running really well. They also agreed to a partial refund for the shipping damage, which I appreciated. I also had an unused 25 ft line set that I needed to return, and they gave me the return information. Overall, even though there were some problems with the delivery damage, the customer service was helpful and the product is working great. I’m happy with how they handled the situation.
