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 bought this DELLA 18,000 BTU mini-split to cool my incredibly hot 200 ft² living room. It's on the southeast corner of my house in Tucson AZ, in direct sunlight from dawn to dusk. In summer, the sun and the 105°-110° air temperatures combine to heat the ceiling and inside walls close to 100°F every clear day. An otherwise excellent 12K BTU portable unit had proven woefully inadequate to handle the massive thermal loads on this room, so it now refrigerates my well-shaded 100 ft° bedroom. This unit works GREAT. It kept this room in the low 70s during the day, and got it to the 60s at night as the walls cooled down. The outdoor unit is so quiet I can't hear it through our old leaky windows, and the indoor unit provides just the right level of white noise for an afternoon nap... until it started making louder noises. That brings us to... 5-star support! The indoor unit started making noise at low & high fan speeds. My handyman, who had recommended and installed this, diagnosed the problem as a bad fan and urged me to contact the company. He has installed many of these units, and the company provided quick and effective support. He told me that the company would send me a replacement indoor unit. They responded immediately to my support request. I sent them videos of the noisy unit as requested. They immediately agreed to replace it, and requested the serial number of the faulty unit (an entirely reasonable request). I replied that I'm disabled, so it would take me a few days for someone to come over here and get the serial number for me. I assumed they would not ship the replacement until I provided the serial number, and that was fine with me... The seller shipped the replacement indoor unit right after I told them I couldn't get the serial number. It arrived today! My unit still worked, and it's much cooler right now, so my situation was not an emergency. If the unit had become inoperative in the summer, every day without AC would have been Hellish... and such prompt service would be potentially life-saving. I highly recommend this mini-split, and I highly recommend this seller. Is there a way to give them SIX stars?

I bought the 18k unit. The installation was straight forward and the unit works great. Della’s customer support is great!!

I’ve put in Mr. cool they work really good. Also Della works really good. Running and no problems

Best money I’ve spent! Made summer/winter much more comfortable. Mounted in the living room.

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.

Its about time I give these guys a great review. I bought one 2 years ago and it was the best thing ever. It ended up snowing in florida and something broke on my outside condenser. It was one day after the one year warranty and they sent us a whole new set up anyways. Its quiets gets the job done and great customer service

Leaks down the wall, even though the drain line is ran properly. Doesn't always cool, when set to cool. For heat it doesn't work the first time I turn it on (just found this out, as I live in the southwest and unit is in my garage), I have to turn it off and on a few times to get it to work. Seems like others are having similar issues.

Honestly, the best product for the price. This is actually my second Della Unit. I have one in my attached garage/gym and had one installed in my detached garage gym. So the 18,000 btu unit was $899.00 and I paid a plumber $500 to run the 220, lines and install so for $1,400.00 I can keep my garage at any temperature that I want. I don't use the heat function so I can't speak on that but the AC function is killer. I mean no matter what the temperature is in the garage I can get it as cold as I want it. It will drop down about 7 degrees an hour. Super quiet, super efficient and super fast. App is not amazing but it is pretty user friendly and works well. Overall, happy with this company and their products. Considering they are close to half the price of some of their competitors it makes it worth it. Do I need AC in my garage? No, but it sure makes me a lot more likely to wax my car, spend time in there and do things in there. A 1st world luxury that is not needed but since I insulated my garage it makes it awesome. So, well worth the investment. My garage is 676 square feet and 12 foot tall and this unit has zero issues, would totally recommend.
