amazing, the process and correcting my issue was taken care of swiftly and hopped out immensely

I WOULD GIVE A 5 BUT THE LACK OF PART AVAILABILITY IS VERY FRUSTRATING

I have purchased and installed several mini-splits over the past few years, including two units from Della. Della by far offers the best value for the money. The included warranty is much better then the competition. The last unit I purchased, directly from the Della website on November 14, 2025. The unit arrived well packaged on November 17, 2025. I had the unit up and running on November 18, 2025. The first unit I 9000 btu Della Unit, was installed in 240- square-foot-tiny-house. It replaced a 12,000 BTU window air conditioner that could not keep up with the South Texas heat. The tiny house in more comfortable and our energy bill went down. I really appreciate the customer service. I was having a problem registering my warranty. I called customer service and spoke to a human being. No long wait and no never-ending-phone-tree. Elizabeth was great and got my units registered the same day. I highly recommend Della Mini splits.

Terrible experience with support. I called 3 times before a technician returned my call. When they finally did call, they said very confidently that my issue was definitely the $84 control board. They added that it’s typically the issue with delta mini splits. Once installed, the mini split still did not work. I used AI and discovered the issue was the remote, which cost only $12.

I was quoted 15000 by a local HVAC company. I turned to Della for an 18000 btu optima single zone system. I went the DIY route and could not be happier. All in $1600 for a great and energy friendly little system. I would highly recommend.

I purchased my mini split off of Amazon. I held onto the unit for several months before installing it. Once installing it step by step according to the instructions, the indoor unit would come on but the outdoor unit would not work. I would get a “LO” error code indicating a power supply problem. After testing the control board, it indicated it was bad. I ordered and received the new board very quickly and installed it. I powered the unit up and the fan of the outside unit came on for the first time. I could hear the reversing valve clicking but the compressor would never come on. I verified that 240 volt’s were going to the solenoid that was marked 110/120 volts. I have ordered a replacement of the proper size and am waiting for it to arrive.

I really liked the option of being able to rent the appropriate equipment to do this ourselves. A couple things could be improved.. I don’t think the box was checked after the previous renter because there was oil left in the machine that was all over everything in the box when we got it, and there was no extra oil to fill it the rest of the way so we had to purchase that locally. Also the instructions for everything were really unhelpful, but I understand as a DIYer that they can’t explain everything. Using ChatGPT and you tube we were able to figure it out and in the end everything on the box worked great for the install. Been running over a week and no issues. If you rent, please remember to empty the oil after using, and Della please remember to check the machines and add sealed oil containers to the box.

We purchased our tri zone system based on what we thought we needed. Our order was on time. We are remodeling so we had decided to let a professional install it. Most were busy. We found one. He did a great job. They work great. In our lack of knowledge we had ordered to much linesets. I called to return the 2 that wasn't needed only to find out that were not returnable. Their window of return is 30 days. We are about 1 month past that. Boxes sealed and brand new. I said what am I supposed to do with them. I was told I could save them or try to sell them. His last reply was a shocker. He said or you could throw them away. So customer service and return policy leaves me with the knowledge that the customer doesn't come first. We had no idea it would take so long to be professionally installed. Who tells their customer to throw new,sealed in box items in the trash? Units work good but we don't recommend this company.
