The product and Della were 5 star…

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…

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.

Hot days of Summer!

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.

The ordering process was very easy

The ordering process was very easy. The unit arrived within a few days and installation was easy with the rental install kit. The unit we bought was for a bedroom and works great for bringing both the temperature and humidity down to a comfortable level. I also really like the ability to start and stop the unit on a schedule. I will be buying another, bigger unit for another section of our house.

Just received my order today July 17th after placing order on June 28th.Della was out of shorter freon lines which will force us to hire an HVAC tech to cut and flare lines! It will be a couple of months before they're installed (new construction)so I will update my review after they're installed and operational

Love the system

The installation went smoothly for the most part. The only problem was I set the toque wrench at the specific settling, over tightened every fitting. I called support to ask what I did wrong and the only thing they offered was maybe just use the lowest setting. After remaking all the flairs I tightened the flair fittings a little below the specified settings. Pulled a vacuum and everything held. Opened valves on condenser, fired it up, works great, love the unit.

We're sorry to hear you're having trouble with your unit. A mini split system must be properly evacuated with a vacuum pump before operation. If the system is unable to pull or hold a vacuum after following the installation instructions, we'd be happy to help troubleshoot the issue. Our tech support is (800) 863-4143, Monday- Friday 6am-4pm PST, and you can also contact us the 24 hours live support team for general questions. We look forward to resolving this matter swiftly. https://dellahome.com/pages/contact

Della is not an honest merchant

Della is not an honest merchant. My contractor installed a multi zone 24000 BTU Minisplit AC. We had trouble from the very beginning. No one could get the second register to work. Not the contractor, not even an HVAC repair company I hired in desperation. I contacted Della Customer Support (Ruby) and I was informed that my contractor failed to register the unit in the first 100 days of the purchase and they would provide no support unless I could show them the original purchase agreement. Really, ever work with a builder in the USA! Stay away from these people they are crooks peddling cheap overseas electronics. If it works after installation bully for you; when it quits you are really on your own. Spend a bit more and get better product and work with more honest professionals. This company will leave you all hot and bothered and not in a good way.

Great product so far

Great product so far. Had a small issue that was quickly resolved. Was actually able to speak with a person who resolved the issue in a timely manner.
The product itself works great and the install kit rental is a game changer. Great value for your money compared to the competition.

Customer service was exceptional

I bought a 3 zone cassette style minisplit system from Della. Install was simple for a GC. I had one issue with the instructions and ran into a mistake that needed a special fix and customer service was exceptional in resolving it for me. And of all the knock off minisplit brands out there. I fully recommend going with DELLA, rather than saving that 3% difference. Della actually lasts.

Generally a great setup

Generally a great setup. This unit works great. Cons: short one item in the line cover kit. The wiring harness from compressor to inside unit was about one foot short for the freon tube length. 9k unit.

I purchased a della portable ac with heat. It was delivered by a 3rd party shipper who threw my unit from the truck onto my sidewalk. The unit was split up the side but still worked. Della actually sent me a whole new unit for free without requiring me to return the original. 3 years later and both units are doing well. Customer service that actually serves is hard to find but Della is where it is at!
