Della Reviews 

It's a pleasure working with Della, especially Lizzie. I have purchased a couple of units from Della, and Lizzie did not hesitate to help us out immediately when an unexpected problem occurred with one of the units. She's a quick problem solver and that's a hard to find nowadays with so many companies. I really appreciate Lizzie being on top of her game!

Tech support directed me right to the problem.

Ac took more than 15 days and it’s still not arriving . And summer is over. I need the ac for the summer not for fall or winter . It shouldn’t take that long to arrive and you guys are not knowing where it is and how long it takes to arrive make the situation worse

Fast and easy customer support with a cancellation and new purchase. Elizabeth was informative and follow through with letting me know that the cancellation was processed so that I could purchase the correct unit I needed. My order was delivered in 3 days. Thank you!

Customer service (Elizabeth) was patient in helping me correct my mistake in timely fashion and get me the correct product to the correct address. What a relief when shipping and delivery can be hectic! The customer service provided was done so in a thoughtful, patient manner that put the customer first. Would highly recommend Della to anyone on the fence about where to buy cooling units.

I had an issue with a new unit that I wasn't able to install immediately after delivery which put me outside the warranty deadline. I had several conversations with Della representatives but Lizzy went above and beyond to take care of my issue and get me a replacement part. She was kind and and followed up with me less than an hour after our first conversation. Because of this Della will continue to get my business!

The mini split system came with everything I needed to install the unit and the install rental kit helped a lot. The reason I gave it four stars is because the instructions in the book was confusing at one part but the instructions for everything else was spot on.

I initially left a message for our A/c guy on a Friday afternoon with the error message code. I never heard back so I figured I’d check with you guys on Monday. Don’t remember the person‘s name that assisted me but they were awesome. I was able to order the replacement parts with my order number ended up installing the part myself.

Fast and immediate shipping. Verified, via chat, that the unit I wanted to purchase was in stock and it was! Can't beat the pricing and shipping.

Very helpful, support responded quickly to my questions

Two parts to this review, first the good stuff; The mini split works great. I have only run cooling for 30 minutes since I finished the install today. The unit is very quiet.
Now the not so good stuff; It should not have taken nearly two weeks to complete a 4 to 6 hour job. One week was lost to damage to the outdoor unit in shipping, not Della's fault. The other week I ended up chasing a problem that actually turned out to be not a problem. I evacuated the system and checked microns of vacuum at 10 and 30 minutes and the vacuum kept climbing stopping around 350 to 400 in at least 8 different attempts to find the slow leak. I ended up disassembling and reassembling refrigerant lines multiple times trying to stop the leak. Also, the torque specification on the flare fittings is way too high. A few times the copper flare was destroyed by the torque on the lines causing me to cut and re-flare the tubes. After several days of not being able to solve the slow leak problem, I contacted tech support. Here I was told that the refrigerant lines should not be shorter than 10 feet, mine were 4 feet, and that this is probably the cause of the vacuum issue. NO Where in the manual does it list 10 feet as a minimum length. I has a nice clean professional installation with 4 foot lines. by changing the lines to 10 feet my installation now looks like it was done by the three Stooges. Very unprofessional and messy. The tech's suggestion was to move the outside unit. Not likely since it's bolted to and through an exterior wall. This should be noted prominently in the directions. Directions need to be clear and complete, yours are neither. Also, I watched the install video several times to confirm that there should not be a change in the micron reading after 30 minutes as demonstrated in the video. In the conversation with tech support I was told that as long as the system is under 500 microns all is OK. I wasted/lost 5 days because of this issue that really wasn't an issue. Another problem, Page 20 of the installation manual shows the inside unit refrigerant tubes individually insulated. A conversation with customer support says that this is unnecessary. It can't be both, clarify what the procedure is rather than offer conflicting information. Generally, the issues I ran into could have and should have easily been avoided and this should have been an easy 4 to 6 hour installation instead of a fiasco of errors. My nice installation is now a mess that I need to figure out how to clean up and my frustration level with Della is very high.

While I appreciate the comments from Della, none of this would have happened if Della provided clear, consistent and concise directions. I now have to figure out how to cover, protect and support two 6 foot coils of insulated refrigeration line and attempt to make this look something better than a thrown together amateur installation. Again, spending more money on fixing what should never have happened.

(Elizabeth) Lizzie was awesome to work with and helped me out a ton. Very fast replies and nice!!

My a/c had been damaged during shipping. Made a call to customer support and they sent me a new one right away. Thanks again for taking care of me

I have been wanting to lower my electric usage as well as be a little more self reliant. I purchased two Della mini-splits, an 18k and a 12k. I installed the units myself. I had my own equipment so I didn't need to rent it from Della. The install was fairly simple but with a good amount of work. I am very pleased with Della's customer service. They were easy to get in touch with and Hector took care of all my concerns in a timely manner. The install instructions from Della and you-tube were very helpful. Both units are running quiet and efficiently. The units were reasonably priced and seem to be well built. I am
happy with Della.

Nicole provided excellent service. She was extremely personable and walked me through the process with ease.

Lizzie is awesome! I had an issue with my Della mini split and she was able to get it straightened out immediately and shipped out a new unit. Thanks again for everything!
