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 mini-split unit because it is one of the few that I could install myself. Although it requires having a vacuum pump and a vacuum gauge set the investment in tools is minimal compared to the cost of having a unit like this professionally installed. Please note: the unit itself is very straightforward as far as connecting the inside and outside units together and charging the system HOWEVER there is a significant amount of additional work that needs to happen to actually get the unit fully installed on your house. This additional work may include running new electrical branch circuits through your house, opening up walls with all of the associated drywall, stucco or siding repair, possible concrete work, possible plumbing work, finishing work to cover the refrigeration pipes, etc. Just be certain that you know what you are getting into before starting this project. That said, I did install the unit myself, it turned out great and I am very happy with it but it was considerably more work than I had anticipated. The unit itself is fantastic! It cools my 12' x12' bedroom down in minutes and has enough additional cooling capacity to keep my entire house cool on a 100 degree day just by placing a small fan at the door of the bedroom that blows the cold air to the rest of the house. At night it keeps the bedroom cool while making hardly any noise. The noise that it does make is a quiet ssshhhhhhh sound that is about as loud as a whisper and it works perfectly as a white noise generator. The outside unit is also very quiet. When I first turned it on I didn't even realize it was running. I chose to wall mount the outside unit on brackets as opposed to bolting it to a concrete slab but I imagine it would be even quieter if it was slab mounted. If you wall mount it you will need to purchase brackets separately. There are specially designed brackets specifically for mini-splits and they are relatively inexpensive. So far my only complaints about the unit itself is the lack of adequate protection for the refrigerant lines. The tape wrap that comes with the kit is woefully inadequate in my opinion and I ran out of the tape with several feet left to go. Even with the tape the lines appear unfinished and are poorly protected from the elements. To address the issue I bought a mini-split duct kit to cover the lines which resulted in a well protected, professional looking final installation (see picture). Consider this step an absolute necessity. I decided not to bother installing the wifi control app on my phone. Based on what I could see the only additional advantage of the app is being able to set schedule times which is a feature that I don't use. Considering the immense value for this mini-split unit I would absolutely recommend it as long as you are an advanced level DIY'er. If you are not comfortable dealing with electrical installations and the National Electrical Code and if cutting a big hole through your wall scares you then I might suggest finding a different solution to your cooling situation.

I've had this for a couple years now and I thought I'd review it. Installed it in the garage and it works great. My dogs love it and I love it. Having a temperature controlled area to work and for my dogs to get out of the sun is awesome. Super easy install if you know what your doing. It's quiet and we run it quite often and haven't noticed much difference on our electric bill. The one I got has a heat pump so it cools and heats.

The DELLA unit is working wonderfully! I did have it professionally installed, but for the most part it was definitely DIY able (biggest problem would have been the need to vacuum the line set down). It does a wonderful job heating and cooling my studio.

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.
