Motto Series 18000 BTU 19 SEER2 230V Mini Split AC, Cools Up to 1000 Sq.Ft, Works with Alexa and Wifi, Ductless Inverter System Air Conditioner, Pre-Charged Heat Pump and 16.4ft Kits

Very satisfied with our DELLA 18000 BTU mini split AC. Despite Della saying this is a non DIY unit, probably due to it being a 240v system, requiring a new 240v breaker install on the service panel, and also a system that needs to be vacuum purged before first use, I was able to self install this unit with no prior mini split experience. That's not to say I had no DIY experience. So, if you have done some prior DIY home improvements and can make sense of basic wiring then you may be able to DIY it yourself. That said, there are a few tips I would offer. First, buy yourself a torque wrench able to do at least 60 Nm torque along with some crow foot wrench heads up to 1" and use it as suggested in the Della instructions. There are a lot of YouTube videos about DIY mini split installs out there where guys say no torque wrench no worries just tighten it "real good". It pays to get the torque right. The issue is mostly refrigerant leaks if the connections aren't right. Do it. Second, buy or borrow a HVAC vacuum pump and gauge set. You have to vacuum the system before releasing the precharged refrigerant. There is some confusion out there about the pre charged coolant. Mr Cool systems pre-charge the tubing, Della precharges the compressor. You have to vacuum a Della system. Third, get a tubing bender and flaring kit. The lines are "long enough" for most average installations. But the 1/2" copper tubing does not bend easily and is easy to crimp and to make useless if the ruined bend isn't cut out. You may need a shorter line and cutting the tubing, re-flaring it, and bending it here and there may be necessary. Trying to loop or snake the 1/2" copper tubing without a bender is risky. Luckily I had or could borrow all the above tools. But I can see from having installed the kit that not having that stuff would be an issue. Lastly, make sure you install a disconnect box by the outside unit. So, all in all, not a big deal to install this unit. Worked great immediately. Cooling our garage without a problem. Also, although most guys think any wiring from the panel has to be Romex we used 12AWG copper stranded without any issues. The Della interconnect is only 16AWG stranded, so 12AWG is prob overkill. The unit draws a max of about 12 amps and recommends a max 15 amp circuit breaker. Although the unit has a count down timer, in other words you set a number of hours after which it will turn itself off, it does not have a scheduling timer that allows you to set a daily routine for on/off, temp, etc. That is one feature I wish DELLA would add. Although there is a companion phone app for controlling the unit via WiFi I did not use that app. My only complaint is the info supplied by Della on wiring the outside unit could be more helpful. Although schematics are included it would be helpful for the manual to show a photo or illustration of the completed wiring block and which wire from which cable goes where. It's obvious, after you have it hooked up. But having a as completed illustration or indication of which block is for the interconnect and which is for the mains and what is intended would be helpful. All that said, the DELLA 18000 BTU mini split is a great value at the price compared to what, to me, are the very over priced Mr Cool systems. It's super quiet inside and outside and the inside unit has a powerful fan. We like it.

I picked this up to heat and cool shed workshop/office. It works perfectly. It's actually a little too big for my 160 sqft space. Normally an oversized ac would cause humidity issues, but I can set this thing to dehumidify mode and it will pull the extra moisture out of the air making it very comfortable. It's very easy to install, but you will need a vacuum pump. It comes with a remote, which is ok, but the phone app is much better.

I recently had installed the DELLA Motto Series 12000 BTU Wifi Enabled Mini Split in my bonus room (about 600+ sq. ft.), and I couldn’t be happier with the results. This unit is a powerhouse! It effortlessly heats and cools the space, keeping the temperature just right year-round. One of the things that really stands out is how energy-efficient it is. Even with running both the cooling and heating functions, my utility bills have already started to drop—such a nice surprise! The 20 SEER2 rating is definitely paying off. The R32 refrigerant also helps make it more environmentally friendly, which is a huge plus. Installation was straightforward, and the fact that it's pre-charged with refrigerant made things much easier. I also love the Wi-Fi connectivity and Alexa compatibility, so I can control the temperature from anywhere. Whether I'm at home or away, I have full control of my room’s climate with just a few taps on my phone. The unit is quieter than I expected, and the overall build quality feels very solid. The heat pump is great during the colder months, and the air conditioning does wonders during the summer heat. I would highly recommend this mini-split system for anyone looking to efficiently heat and cool a medium to large room. It’s saving me money, is easy to use, and keeps my space comfortable year-round. Truly a great investment!

I purchased this unit for my garage in Minnesota after a very humid summer. The install was very straightforward with no surprises. The only caveat is that you have to already own a manifold and pump or purchase one As for the operation of it, I installed it in autumn so I did not need to use it until winter for heat The unit is pretty close to silent and did a fantastic job warming up and maintaining temperature in a two car garage One thing I was amazed at is although this is rated for 15° it is still producing heat at -20° It’s not as efficient as it is in warmer temperatures, but it’s still blowing out 90° air So mechanically, the install and quality of the unit seems great. Software wise, they could use some help both with the remote control and the app First, the temperature only goes down to 60 I would really like to keep my garage at 45 to 50 Second, the timer function only allows you to turn it on or off in a couple hours. There is no way to turn on and off at a scheduled time every day. Pros: Straightforward, easy install Very quiet Far exceeds expectations in cold weather Has a dehumidifier function Cons: The filter is pulled out the top so you cannot mount it tight to the ceiling Cannot connect it to an external thermostat Cannot schedule it based on time of the day The heater thermostat should go lower

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!

Installation was straight forward with all the parts needed except your tools. I paid for an HVAC person to charge the unit. This appears to be an upgrade from the Della Mini Split I purchased 3 years ago. Both units are working great! I have about 500 square feet of space per unit. Last year my first unit kept the room pleasantly cool in 110 degree heat. The heater kept the room warm at 15 degrees in the winter. Lastly, the remote to my second unit was missing with the product. Customer service answered my request for a replacement within 4 hours. Amazing!

I bought this unit a little over a month ago. I have another one of these exact same model installed in a small shop on my property, it’s working fine. This new one was initially working fine but last week I went out to turn the heat on in the garage and only room temperature air blew out. Concerned that I may have a refrigerant leak, I called a local hvac repair company. Yesterday, the tech checked the levels and even vacuumed out all of the refrigerant, pulled a new deep vacuum on the system and recharged it. Still the system did not produce any warm air in the heat mode. The tech said the unit was not working in the ac mode either. He determined that the compressor was not ramping up. He said to replace the compressor it would involve a lot of labor and additional refrigerant and that would cost more than the unit cost in the first place. I think the tech felt sorry for me and only charged me 300 dollars for his labor and fresh refrigerant he added to the system. I have emailed Della through Amazon customer service. In the email , I told them what the tech said and did. I’m waiting to see what happens. They have emailed me back once already wanting to know what the system was doing (I feel like I already explained that part to them) and if the tech “wrote a report”. I hate to call the tech back to ask for additional labor of writing me a report. He was already at my property for 3 hours working on the system. I’m around 1400 dollars in to this system so far. I just spoke to Hector with customer service and he said that I must have gotten a bad compressor. He’s said that they are sending me a new outdoor unit.

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.
