I can't say enough great things about Della and their incredible customer service. From start to finish, the team went above and beyond to make sure everything was taken care of. They helped me in multiple ways, patiently worked through some unexpected technical difficulties, and never made me feel like I was just another customer. I sincerely appreciate all of their help andI look forward to working with Della again in the future. Highly recommend!
The installation manuals could use some work. The torque specifications are accurate in some places and not in others. But the email support is very responsive and helpful.
Good technical support. High quality product and high quality rental tools. The process of returning the rental tools was easy. Areas for improvement: I tried to rent a DIY set for one week. I talked with an agent about the availability. The agent said that plenty of on-week sets were available. However, this was not indicated on the site when I made the order. there was some difference between what the support agent told me and what I was able to order. As a result, I had to rent the two week set. This cost me an additional $50. One other area for improvement is that the instruction video did not exactly match the rental tools. This was a critical step. I had to use my own knowledge about mechanics and HVAC to figure out how to use them.
Very competitive prices, very fast shipping, great documentation & support. If this unit lasts half as long as my last one I will be happy.
Della has been been great when you need help you can call and get a live person to talk to. They are very professional and helpful. They stand behind there products. I have told a lot of my friends about my experience and they ask me to send them information about Della products. I highly recommend them. And I Would Like To Thank Lizzie For All Her Help She Was Awesome.
Very affordable, easy install (by a professional), very quiet and efficient system that is doing an excellent job keeping cool in this 95+ degree heat so far.
Overall, we are very happy with our purchase and the system works really well. In fact, we would absolutely install it again and are already planning to buy another one. However, if you are planning to install this yourself, there are a few important details you need to know before you get started. Installation and Hardware Details The Compressor Stand: Be aware that the compressor stand is not universal. Make sure you double-check and pay close attention to your specific compressor dimensions before purchase one of the two available. The 30-Amp Quick Disconnect: The disconnect box on the website does not come with the required fuse. To make matters worse, the specific fuse it requires is incredibly difficult to find. We were never able to source one locally, so we ended up buying our own separate disconnect box. The one from Della is unfortunately useless to us now. The Rental Kit and Instructions Vacuum Pump and Oil: The rental kit was decent, but it could be improved. The vacuum pump oil had spilled all over the inside of the kit during transit. Luckily, there was just enough oil left to run the pump, but it made a mess. Outdated Documentation: The instructions for operating the vacuum pump had changed, but the printed documents included in the kit did not reflect these updates. We had to call customer service to have the updated instructions emailed to us. Customer Service and Technical Support Excellent Support: This is where Della really shines. The customer service and technical help are both top-notch. When we called about the pump instructions, they were incredibly helpful and got us the information we needed right away. Final Verdict All in all, the minor installation hiccups were worth it because the system itself runs beautifully. Just be prepared to buy a separate disconnect fuse (or box) and double-check your dimensions, and you'll be good to go. We definitely recommend it!
Great affordable unit all parts needed are included
House wasn’t ready for install when unit was purchased. Winter hit and had to wait for siding install then when I went to install I found out there would be no warranty coverage since it was not installed and registered in the first 100 days even though all equipment was new and in unopened boxes. Very disappointed in this. Unit is solid and works very well other then that.
We're sorry to hear about your disappointment and appreciate you sharing your experience. Our warranty registration requirements are outlined in the warranty policy, including the registration period. We understand that construction delays or seasonal conditions can sometimes make installation within that timeframe difficult. Thank you for your valuable feedback. We'll share your suggestion with our team as we continue to evaluate ways to improve our warranty policy and customer experience. We're glad to hear that the unit is working well, and we appreciate your continued support.
First off, I was very impressed with delivery time. I placed an order on 6/15 with free delivery and received it the next day! The DELLA 42" Ultra Quiet Smart Tower Fan with Voice/APP/Remote Control is quiet and coolans my bedroom in about 5 minutes. I actually get cold! Fantastic product.
Fast shipping. Great product. Easy install.
The shipping company Della uses is unbelievably slow and you can’t get anyone to speak with about the shipping time on the shippers end… Della please change the shipping company! The product is great
Dear customer, thank you for taking the time to share your feedback. We’re glad to hear that you’re happy with the product, and we’re very sorry that the shipping experience felt slower than expected. For transparency, once an order is placed, we typically require 1 business day to arrange shipment. During peak seasons, this may take 2–4 business days. After the order is processed and fulfilled, transit time is usually 1–3 business days depending on the carrier and destination. We understand that any delay or lack of updates during this process can be frustrating. While shipping is handled through our logistics partners, we understand that the overall delivery experience reflects on us, and we are continuously working to improve both processing efficiency and shipment visibility. If you have any unresolved concerns or would like us to review your order status in detail, please feel free to contact us and we’ll be happy to assist. We truly appreciate your feedback, as it helps us continue improving our service.
I bought 3 room heat pump ac/heat units portable in 2024. After 2 years of purchasing one unit quit blowing cold air. I called 3 times trying to get troubleshooting help and they said the unit was discontinued so they could not support me with either parts avalability or technical help. No parts diagram or troubleshooting available. They are made in China, so that explains it.
Dear customer, I sincerely apologize for the inconvenience you're experiencing. We can certainly provide troubleshooting guidance to help identify possible causes. However, we do want to be transparent that for portable units, replacement parts can be very limited, and in many cases parts are not available separately or are difficult to replace. We apologize for any inconvenience.
The shipping was fast under a week from order to delivery. It was packed very good. This is the first mini split I have had. Been watching videos and getting nerve up to try it. Decided on the Della because they got good reviews and price was good. Before I ordered it I called Della 3 times to ask different questions that I had. First of all they answered my calls and they were very knowledgeable. I ordered the Serena 9000 for our bedroom. I installed it today took around 3 hours. I had already installed all the electrical except the breaker. Everything went together great I even cut my lines off so I wouldn’t have all the extra hanging out. I have never used a flaring tool before but after watching a video it was really easy. Hooked it all up used an adjustable torque wrench to tighten lines. I bought a vaccum pump and gauges and checked for leaks. I also ordered the line set cover and it was worth every penny. Inside and outside units look great and line set cover gives it a professional look. I had heard these were quiet but it blew me away how quiet they are inside and outside. Everything seems be working great. Will definitely buy two more for rest of house.
Great sales, communication, and shipping.
Good product. Cools fairly well. Quiet. Simple remote. I'd buy another one.
The Della support response is almost instantaneous. Very impressive. I've noticed slight errors etc in their documentation, but the support folks seem to know what's up. The units are top notch as well. The Della app is better than anything else on the market.
UPDATE ON CUSTOMER SERVICE... Well I was contacted by customer support and they are outstanding in taking care of customers and did rectify my issue... We will definitely buy and be a long term customer and company that will offer their products to our customers as well... Excellent job Hector and earning my trust and business going forward...
We're sorry to hear about your experience and understand how frustrating it was to have your unit down while waiting for the replacement part. To clarify, for PCB replacement requests made more than 100 days after purchase, our warranty policy requires the original PCB to be returned to DELLA. We understand this adds an extra step, and we appreciate your cooperation throughout the process. As for the shipping time, we have multiple warehouses across the country, and replacement parts are not always shipped from the warehouse closest to the customer. Depending on inventory availability, parts may need to be sent from a different location, which can sometimes result in longer delivery times than a complete unit order. We appreciate your continued support and feedback. If you experience any issues after installing the replacement part, please don't hesitate to contact us. We'll be happy to assist you further and work with you to get everything running properly.
Called customer service and was speaking to Nicole and she did a great job assisting me. She was very helpful.
