DELLA 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 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.

Not sure how long it will last, but everything seems well made. Installation was super easy, O Riely’s loans out for free the maniflod gauges and vacuum pump needed to install. If you don’t vacuum the air out of the lines it’ll mix with the freon and turn acidic and ruin your new AC. My only complaint is the line set they provide is too short for any practicle use. If you figure the condensing unit is outside near the ground and the evaporator unit is inside near the cieling, the copper lines provided are too short if you have standard 8 or 10 foot cielings. Yes, you can buy longer copper tube anywhere, but its not that simple, if you add additional length you then also need to add additional refrigerant, and this odd ball “new” refrigerant proved to be impossible for me to find anywhere, not to mention you’ll also need to weigh in the additional charge and check it all on gauges. It would have been a lot simpler had they just provided 2-4 foot longer lines (and appropriate charge) for a typical install. My only other complaint is there are no physical controls on it, you can only turn it on/off with the remote or app (I haven’t tried the app). Maybe I’m just old school, but I would have preferred at least a physical on/off button on the actual unit. The complaints are minor though, the real mind blower is how absolutely quiet the inside and outside units are. When I first turned it on from the outside disconnect switch I thought something was wrong, it wasn’t making any noise at all, I had to take a closer look to see the fan was turning outside then wondered when the compressor was going to kick on. Went inside and it was already cold in there, the compressor makes no noise, no vibrations. My neighbor is 1/4 mile away and I can hear his AC unit kicking on all the time, its actually louder 1/4 mile away than this one is right next to it. It cools great, even on hot humid days. I’m really hoping the heat pump function works as advertised this winter. They claim it works with an outdoor temp down to 5 F, our old heat pump, even when it was brand new, wouldn’t work if the outdoor temp got to just 32F. I’ll update this review come winter after seeing how it does. Yes, I highly recommend this, just make sure you size the BTU right for the space you have, you can go to large or to small, bigger doesn’t always mean better with AC units and trying to save from buying to small of a unit will cost you in the end from working it to death. 1 more huge plus worth mentioning, they did an exceptional job writting the installation and user manual, one of the best manuals I’ve seen in a very long time. The print is a human readable size, not microscopic. It’s not on cheap photocopy paper that’s mostly black blurs like most manuals, even the pictures are clear. It’s also all in english, not 40 different languages. I was just about as impressed with the manual as I was with the unit, a refreshing change from what’s become normal, job well done to who ever made the manual.

Part II: Let me start by saying again that this ordeal has coincided with me having breast cancer and undergoing a double mastectomy. The seller sent a THIRD defective product. This one also does not blow warm air. In essence, the heating portion doesn’t work. So, when New Orleans underwent an unprecedented blizzard a few weeks ago, and we were blanketed with snow and cold for days, we had NO HEAT!!!!! We are expected to get unseasonably cold weather again next week with NO HEAT!!! The seller keeps telling me I’m out of the refund time frame. I purchased this in the summer. How could I have known six months later that the heat wouldn’t work. Part I: Let me start by saying, I have breast cancer and just underwent a double mastectomy a month ago. I bring this up because I should not be having the trouble I am having, in my condition, with this seller who wants to send me, not a second replacement, but a third replacement for this unit, which I originally purchased about six months ago. I live in New Orleans where summers are brutal. It took a good portion of the summer to get them to resend a replacement unit for the one I ordered in June, which registered a P5 message from the moment it went up. What’s more is the technician I had putting it in had to PAY to speak to someone with the brand about what he might be doing wrong. It was only after that that the seller admitted there must be something wrong with the item after they could troubleshoot no more. When the second one came, it worked. But, I have to say I wasn’t impressed with its productivity. It did not cool the two rooms to the degree I imagined it would, though it was not unbearable. However, when we tried to use it a few weeks ago for the first time for the heat, it would not blow warm air, despite being set to 85. It was on the whole day, went off in the middle of the night, and would not come on, at first, the next day. When it did, still there was no warm air. Nor would the inside unit register a temperature as it had been doing all along. The seller wanted me to send a 15-20 video of it not coming on, though my complaint was about it not warming up. Then, the seller wanted me to send a 15-20 minute video of it not warming up. I asked repeatedly how I was supposed to video it not warming up. The seller stopped contacting me until I contacted Amazon. Then, the seller let me know that I was out of time on a refund. They offered a third replacement. That isn’t what I wanted, but I was forced to agree to. Once I did, they were back to asking me to first send a video. Then, they wanted to have someone troubleshoot with me. Then, they wanted to send only part of the unit, though they had offered a full replacement. I have never had an experience like this on Amazon, who I am also displeased with since they refused my request for a refund because they only do it in the instances of wrong items sent. How isn’t a dysfunctional item not the wrong item?????

Works well for my den which was an add on. Easy to operate. Good value for the money.

Heats and cools great. Quiet operation and low energy consumption. Was easy to install. Only negative was that I never could get the wi-fi to connect for which was a big part of my reason for choosing this brand.

Even with the outside temperature 90 Plus with this unit my central air didn't even come on, at night it dropped to 30 the heat was excellent 108 degrees was coming out of the unit, the tech support service was really good and spoke English

Easy instruction manuals,easy install.worked perfectly as it should,living in the country I have limited cheap heat resources,this thing has heated my midwest farmhouse up quik and is the best heat this place ever had, don't know yet if it'll save $$ on utility bill,love this system,you won't be dissapointed,now my costway unit was a joke,should just bought 2 of these systems from the get go.very quite machine too.
