I like the product and the installs was very easy. The directions were easy to follow. So far it’s been a great experience from ordering to install.

So far so good but not totally installed yet which is why only 4 stars. I accidentally ordered wrong length line sets and although Della doesn’t generally do exchanges they have decided to give me 2 options to help me out with my issue. Now changing my review to 5 stars.

Had units only two years and the freon is no longer allowed by the EPA, which I question as that information is put out long before it becomes law. I feel screwed that I had to buy an entire new mini split because of this and the fact the U joints were leaking freon at the coil so I question their quality as well. I would have give only 1 star if they didn't provide me a 50% discount on the new unit. Hope this unit lasts longer than two years!!! I noticed they posted a response. As usual they BLAME the installer and not their manufacturing issues. The U Joints are attached the coil inside the unit, my HVAC guy had absolutely nothing to do with them leaking where they were soldered to the coil.

Dear customer, I do apologize for any trouble this has caused. Certain refrigerants are being phased down gradually under environmental regulations, but they are still widely in use and supported, and service/replacement options remain available. Regarding the issue you experienced with leakage at the connection point, we are sorry to hear that. However, in most cases, refrigerant loss at the flare or connection is related to installation, tightening, or sealing conditions rather than the sealed system itself. This is why proper installation and pressure testing are very important. We are truly sorry that this situation led to your inconvenience and additional cost. We also appreciate that you accepted our 50% goodwill discount on the replacement unit, and we hope the new system provides you with a much better long-term experience. We value your feedback and will continue working to improve both product quality and installation guidance to better support our customers. If you need any assistance with your new unit, please feel free to reach out to us anytime—we are here to help.

We received our dual zone mini-split quickly and in perfect shape. We had a few questions about our unit and customer service was extremely helpful. Della offers a great product at a great price.
