DELLA Vario Series 18000 BTU Wifi Mini Split AC, Work with Alexa 21 SEER2 Cools Up to 1000 Sq.Ft, Energy Efficient 230V Ductless Inverter System with 1.5 Ton Pre-Charged Heat Pump & 16.4ft Kit

I purchased 2 of the 1.5 ton 19 seer units a year ago. I purchased based on the reviews of the experienced hvac technician. My buddy is a hvac technician and was skeptical at first but he is also now a believer!! Easy installs on both. I am using them to help out 2 standard 5 ton heat pumps that were just not cooling the 5400 square feet with high ceilings that we have. I installed these 2 units across from each other at balcony level of the upstairs of a formal living room that has 24’ ceilings and is approximately 1,000 sq feet with 16ea 4’x8’ windows in it. These units will keep that area at 64 degrees throughout the 95-100 degree summer. They have also allowed the 5 ton units to now hold the rest of the house at 65-67 during the same 95-100 degree days. So in a nutshell, they work!! I did have an outdoor unit of one of them croak just a few weeks ago, but a couple of emails and sending a video of the problem to customer service and boom!! They shipped a new outdoor unit to replace it and it’s back up and running again. I can say it sucked that 1 croaked out, but… it was great to deal with a company that stands behind their products and quickly got my problem resolved. I plan to purchase at least 1 more for another large room to take more load off the big electricity sucking 5 tons. These units are super quiet, have to look up at them to make sure they are running. I have absolutely zero complaints and would recommend these to anyone. Oh, I guess 1 complaint…. They say precharged but both units froze up within a few minutes during initial start up, My buddy had to add about 1 lb refrigerant to each. Mine had the 16’ line sets, so I bet the units are precharged for the units with only 6’ line set. Just keep that in mind.

This is my second Della mini split my first one I've had over a year no issues so decided to replace an existing old mini split with this one which is an upgrade in both features and btus and has an auto mode. It seems very efficient and not noticed power bill increase even though this was 18k btu compared to the old 12k btu one it replaced. Comes with pretty much everything you would need for basic install minus a vacuum pump. You can rent one from Della though if needed. I ended up buying a vacuum pump set for first unit and been reusing that for this install. Remote with remote temp sensor is nice to place where you want it to feel the set temp at. Airflow works great spreading it out throughout the big open room space. If power blips it comes right back on like it was previously. It's easy to clean and honestly a steal for the price. Wiring and the manuals are all very well done as are there video guides. It's also very quiet almost don't know it's on other than that it's working. Very pleased and recently just ordered a third Della mini split to replace the final window unit in house. If on the fence definitely give them a try.

This is my 17th della Mimi split system, that I install in Rochester New York and in Jamaica.Best units ever

I installed this unit in a small, 3 bedroom house and it works great. Runs pretty quiet and cools the place very quickly.

Do not buy this unit and beware of any unit you buy ! My Dad ordered this unit and had it installed by a professional in February of 2025. It has been leaking refrigerant inside his house and he has been trying to have it fixed, the AC guy is refilling the R454B and has been since installing the unit because he was not able to pin point the leak , this last time my Dad had to call a different company because the first one could not be contacted any more so the new company he called ran a leak test and found the issue right away and told him the unit has a manufacturer defect and he needs to replace the inside unit, now we have been two find a unit to replace it but it is no longer under warranty so he has to fork out the money for that and that is bad enough but when we started trying to find a replacement we were told they do not have the unit for purchase and cannot recommend anything compatible with the outside unit because of the refrigerant R410A, it uses is being phased out so now my Dad has to purchase a whole new system and what is even worse it was signed into law in January of 2025 to phase out any units using R410A , the units sold and installed BEFORE January of 2025 can continue to be maintained so why were these units still being sold in February of 2025? I feel like my Dad and I have been conned not only by Amazon but also by Della. Do your homework and save your self from the headache and financial drain because no one else will. The AC companies did not tell us this is not able to be replaced because of the refrigerant it uses, Amazon kept right on selling the units and so did Della.

Unit works very well installed this mini-split in my double car garage which doubles as my workshop. At 111 gegrees outside I was able to easily maintain a cool 77 degrees in the shop. The only issue on installation was I chose to take the pipes out on the left end of the unit instead of the more common right end. The instructions say you can do it either way but the piping and control cable and drain line is built to exit through the wall on the right. After doing the left side and mounting the unit on the wall the piping with all the insulation wrap wouldn’t allow the unit to fully lock onto the mounting plate leaving about a half inch gap between the wall and bottom edge of the unit. Just too much bulk to squeeze into the cavity provided inside the unit. I would suggest you install with thr piping exiting only on the right.

I installed this Della 18000btu Mini Split. It works great & it's very quiet. So far it is keeping things cool in my 1024 Sq. Ft. Workshop.

Works amazing for my 20x25 garage. Fairly easy to DIY install.
