Size: 9,100 BTU - 115V - 20.5 SEER2
I've had this mini split for about 2 months now, installed and working for a little over a month now. I have a finished insulated work space in my pole barn that I use as my office since I work from home. I bought this unit to cool and heat the space. I live in Michigan and we have hot humid summers and very cold winters. I attempted to do this as a DIY and bought this unit since it was the cheapest one I could find - I didn't want to spend a lot on it since it's not in my house. First word of advice, this is VERY difficult to install as a total DIY. While mounting the unit, drilling the hole in the wall, running the lines, installing the outdoor unit and running the electrical for it isn't that hard, the HVAC portion is tricky and you really need to know what you are doing in order to do this correctly. The lines must be vacuumed before releasing the refrigerant or you risk having moisture in the lines which will ruin these units over time. I ended up doing most of the DIY myself but called out an HVAC company to pressure test and vacuum the lines and add the refrigerant. It turned out that I did have a leak in the lines, one of the connections needed to be reflared. It's been up and running for over a month, and it quickly cools my office space and keeps it nice and comfortable. This unit uses hardly any electricity. I've monitored the usage while it's running and my total usage for my barn was about 800 watts, including the lights and my computer and monitors, so this thing is super efficient. Before I installed this I was using a portable AC unit (one of the ones where you connect an air hose to your window) and my electric bill for my barn dropped by half after installing this and getting rid of the portable AC. Both the outside and inside units are whisper quiet. I will come back and provide an update in the winter months with how well it heats when it gets really cold outside. So far, I'm very impressed with the quality considering the price, and plan to install a few more in my house since we don't have central AC currently. Update #1: Nov 15 - it's starting to get chilly outside and this thing is effortlessly keeping my office toasty warm! The coldest morning we've had so far is around 30 degrees and was still kicking out plenty of heat when it turned on. During the summer I would turn it off after I was done working and then turn it back on the next day when it started to get warm. Now that it's cold all the time, I'm leaving it run 24/7 and still my electricity usage hasn't gone up too much. Still very impressed with this thing. My one (minor) annoyance is that I've noticed that it seems to keep the temp of the room roughly 5 degrees beyond the set point. For example, in the summer if I had the AC set to 75, it would keep the room at 70. On heat, if I have it set to 68, it keeps the room at 73 which for me is way too hot. I've since learned to set it 5 degrees cooler than I actually want it. A little annoying, but not enough for me to remove a star. I still give it 5/5. Will update again in the middle of the winter when it's much colder outside. Update #2: Jan 9 - except for a warm spell right after Christmas, we've had consistently cold weather here, including many mornings in the single digits and daytime highs in the teens and the Della mini split is still kicking out plenty of heat and keeping my office in the 70s. I have noticed my electric bill for my barn increase quite a bit since the winter started, but that is expected as these systems consume more energy for heating than for cooling. I've also seen the defrost cycle kick on quite a few times and it keeps the coils on the outside unit clear of ice and frost. I'd say this is performing better than I had expected and I still give it 5/5 stars after 7 months of use. Update #3: 1/26/26 - since so many people have found this review helpful, I thought I'd come back and provide another update - it's been almost 2 years since I first had this mini split installed in my office and I'm still impressed with it having been through 2 summers and now in the midst of the second winter. The main reason I wanted to provide an update here is that - as anyone living in the Midwest knows - we are currently experiencing one of the coldest winters in recent history and it's been significantly colder than when I left my last update last January. We've consistently had below zero temps (lowest we've had so far is -13F) with daytime highs in the single digits (coldest was a daytime high of 1 degree F) and the Della mini split is STILL pushing out warm air and keeping my office at a comfortable 70 degrees in these extreme cold conditions. I will say that I am starting to experience an issue where occasionally the unit will become unresponsive to changing the temperature either with the app or with the remote, it will beep three times indicating some sort of error and then return to the previous setting. I have not been able to figure out what this means or identify any specific error, and the only thing that solves it is flipping the breaker, waiting 10 seconds, and flipping it back on. This has happened about 3 times since the beginning of this winter. I do wish the app was able to display error logs or help diagnose any potential issues. It could also be a firmware issue that might be solved with an update? I don't really know but overall I still rate this as 5/5 stars and would buy it again!

This is the second della unit I buy. So far both have been working very well. They are easy to install, and a cheap vacum pump and gauge set will save you a lot of money by DIY'in it. As for durability, my first unit is just about under 2 years old and this new one has been installed for 2 months. Both have been working great. The remote and phone app are both OK, nothing special.

UPDATE: it has been over two months now and the device will no longer turn on through the app. It turns on for a second then shuts off immediately. This is not going to last long and is not worth the money. Invest in something else. This is not something you can leave running through the night. There is no automatic setting that you can set the temperatures to. As you can see in the photo, I have the heat set to 70 and it is now 77 in the room…… it eventually turns off but it is a sauna in here by the time it does. I like the Wi-Fi connection ability, and it does heat/cool well, I just wish it would shut off within a degree or two of the set temperature. It even came on when it was still 76 in here to heat it more when set to 71!!! I will survive as this is just to heat/cool my exercise room so I don’t need it all day every day, but if you are buying this for a lived in space, keep that in mind.

I want to recognize Fernando Vasquez from Della Support for truly saving the day. Before doing so, I’d like to provide some context. I previously purchased no name mini split systems from eBay, and in just over a year they began to fail. Determined not to repeat that mistake, I thoroughly researched mini split manufacturers with strong reviews for both hardware quality and customer support. During my research, I came across Della. Fast forward to 2025: I purchased three Della units, all of which worked perfectly. However, during a recent cold spell here in Florida, one of the units failed to produce heat. It took a bit of navigating through Della’s support channels, but I eventually connected with Fernando. He took the time to listen carefully and acknowledge all the troubleshooting steps I had already taken to confirm the unit was defective. After reviewing everything, he fully covered the unit—something I am extremely grateful for. I chose Della specifically for the assurance of quality support if I ever needed it, and that turned out to be the best decision I could have made. Thank you, Fernando, for your exceptional help.
