DELLA Vario Series 12000 BTU Mini Split Air Conditioner Work with Alexa with 1 Ton Pre-Charged Heat Pump Ductless Inverter System, 19 SEER2, Cools Up to 550 Sq. Ft,16.4ft installation kit included

I bought the 24k mini split with a wall mounted head unit. Unit arrive with the cardboard box a little beat up but the unit itself in excellent condition. Delivery was exactly when predicted.Setup was straightforward, took most of a day but I had to run the electrical service also. Templates were clear and easy to follow, mounting brackets were easy to use and level, only thing not specified in the directions was the minimum line length for the unit. Della customer service immediately responded that for this specific unit is 9 feet. Evacuation and flaring were straightforward with what appear to be good quality fittings on the unit.The line cord is stranded so you might want to tin the ends when installing. The plastic through wall sleeve was pretty light duty - I ran my line set through a PVC pipe instead and the rubber pads for under the unit do not look like they will stand the test of time when installed on my wall bracket, but everything else seemed pretty decent quality for the price point.The unit has a strong blower, with a lot of options and it blows very cold even on an 87 degree day. Lots of features and wifi integration that I have not yet explored. I am giving this unit 5 stars for value and I will update this review if anything happens that changes my opinion.

The media could not be loaded. The unit arrived well packaged with no damage. I bought the 24,000 BTU SEER 19 model. It can be powered from a 20 amp or 30 amp protected 240 Volt 2 L1+L2+GND power feed. The unit uses 15 Amp or less at 240 VAC which is impressive efficiency for a 24,000 BTU unit. Both indoor and outdoor units are a lot quieter than I expected. Neither has any strange vibrations or noises coming from them when running.I did self installation and you must have a second person to set the 90 lb. outdoor unit and to hang the 60 lb. indoor unit for the 24,000 BTU size. Be sure to wrap the line set tight so it moves freely thru the 70 mm thru hole you pass the line set, drain, and indoor power cable thru. I did the default piping mode 2 where the thru hole is directly behind where the drain, lineset, and power connection is located on the indoor unit which maximizes the amount of lineset and power cable you have on the outside to reach the outdoor unit. IMHO it also makes installing the indoor unit easier.I used a single stage vac pump and a manifold gauge with R410a adapters to self evacuate the line set. The instructions are very clear for what steps to follow. I used a standard automotive 3/8" socket drive torque wrench with 3/8" crowfoot adapters. I'm sure there's some error in the actual torque but it gets you in the ball park so you don't under or overtorque the flare fitting connections. The huge price difference between Della and Mr Cool Mini-split systems made up for spending $ 100 for a vac pump and manifold gauge set so I could avoid paying a AC tech to come out and do the Della as a self install.The manual said mount the bottom of the indoor unit 98" ( 8' 2" ) from the floor. I called the Della install support # and they said NO it does not have to be mounted that high, and just needs to be mounted so that the top is at least 8" from the ceiling. I followed standard mini split indoor unit install practice and mounted the bottom of the unit 6' 0" above the floor which put the top of the 24K BTU unit 7' 2" above the floor.This model has WiFi based internet connectivity and a good smartphone app that gives control over all the important functions. It also allows you to pre-program daily schedules for when to power the unit on or off and what temps and fan speeds to use. I used the iPhone Della+ app.Was able to connect it to my WiFi only by using the manual connect method, but the Della+ iPhone smart phone app led me thru it.The CON items I'll note: You remove all the protective packaging from the indoor unit in order to connect the electrical cable that goes to the outdoor unit. It is not connectorized. So you have to be careful not to mar the plastic on the indoor unit as you continue installation after connecting the electrical cable. The unit modes are not displayed with words, only with small icon symbols that are not obvious to me. You will want to make a copy of the Remote Control Display manual page for reference until you get used to it. The unit is close to worthless without the remote - be SURE to not lose it. There is a wall holder so you can put on the wall right next to the indoor unit. The unit has an Alexa skill set but the current one for this "TL" series mini split ( as of July 2024 ) is close to worthless as it only allows the unit to be turned on and off from Alexa.One final CON: The US federal government changed the requirements for getting the 30% federal tax credit for 2024 and this unit does not meet the criteria. There is a new series of Della mini-splits that does meet the criteria but they are not yet listed for sale on Amazon. The new requirement to get the 30% rebate for 2024 is a Heat Pump HSPF2 rating of 8.5, and an AC SEER2 of 15.2 . This unit's HSPF2 heat pump rating is slightly less.

Great little Split system. This has just recently been installed in a sunroom. It keeps the room relatively cool with all the glass on its south and west side, but we have not gone through the Oklahoma Summer yet. The unit looks good and functions well. I like the oscillating feature of the vents that move the air around the room. I like that it is Wifi connected and the remote is very useful. (Please read the instructions on its use, as it is not very intuitive beyond turning it on and turning up the fan.) Overall (so far), I would recommend this unit. Please note that the installer had to charge the lines and vacuum the unit (Cost extra for freon and labor), total cost for installation was about $1200
