DELLA Vario Series 9000 BTU Mini Split Air Conditioner Work with Alexa 19 SEER2 Cools Up to 400 Sq.Ft Energy Efficient Ductless Inverter System, Heat Pump Pre-Charged and 16.4ft Installation Kits

Third time turns out to be a charm. First system I purchased (different brand) was delivered without the inside unit. Amazon never located the missing carton so it had to be returned. Second system (also a different brand) appeared to be low on freon. When I opened the freon valves, no sound of moving freon and no change in pressure on my manifold gauge. Outside unit would not come on. I emailed the manufacturers customer support and the next morning submitted a request via their website. That was last week. Still no response from them. So, the second system was returned. I chose Della this last time because they advertise their customer support. The installation went exactly as it should have and the unit is working flawlessly so far. As others have said, it is quiet both inside and out. Easy to sleep with it running on quiet setting. It is fully featured with the swing capability for air flow both horizontally and vertically. Air is cold in cool mode and quite warm in heat mode. I especially like the app. If I wake up cool or hot in the middle of the night, I can adjust any settings without having to get out of bed and find the remote. As with other systems, installation requires a vacuum pump and manifold gauges or a vacuum gauge. (Lots of videos on YT for the entire process). My manifold gauges were old and designed for 134a in cars, so I purchased an inexpensive set and an inexpensive vacuum pump on Amazon. Both worked great. I also did not like the extra line length laying around outside, so I purchased a inexpensive flaring kit (on Amazon) and shortened the lines. It was easy to do and I am pleased with the end result. If you want to do the same and have no experience with copper tube flaring, suggest you cut the lines a bit longer than you need so that you can make more than one attempt. My first attempt was not good but second time was perfect (or close enough). Lots of videos on YT on how to properly flare a copper line. One thing I did not pick up on YT was the proper technique for reaming the line after cutting (with the proper tool). I was much too aggressive in my first attempt. Very little pressure is required. A finale humorous note: these Chinese companies seem to use the same printer for their instructions - with different covers for different brands. Both the second system and this Della had the exact same instructions - down to the grammatical errors. May 2025 update. Have now been through an entire heating season. On an especially cold day (for us) - in the 20s - I tested the inside temp. It was 112 degrees coming out of the louvers! Impressive! Have only used it occasionally for cooling but am extremely satisfied in both heating and cooling mode. I plan to buy an 18000 btu for our lake place when my old unit dies.

I purchased DELLA 9000 BTU from Amazon. The unit was delivered on time, perfectly packaged and clear instruction how to install it. Installation took a little time but was not too complicated. I decided to run the system before buttoning the system for the final time. I run the system for about a day or so and it work great. My room is about 340 sq ft and it was cooled down very quickly. The system worked fast and quit. I finally got a good night sleep in comfortable and quit environment. During the weekend I disconnected the system, configured for the final time, reconnected the electrical cables and the pipes. Then I run the final test to vacuum the system. When running the final test I used a bad cable (purchased from a store) that had a bad connector. As the test run the coolant in the system leaked through the bad connector of the cable. I was very frustrated and called DELLA customer line for help. I did not hope that they can do something for me since the malfunction was entirely my fault. DELLA customer service representative was very curious and kind. I could not believe that she offered me to replace to outside unit for no additional cost. It’s extremely rare to get such an exceptional customer service. A great system that cools down and warms up your house, works through wifi and Alexa and run very quietly. I highly recommend DELLA to anyone who is looking for an excellent AC system and for great customer service. Thank you for everything. Performance, efficiency, size, cost.

I don’t even know where to begin. I have had this system for almost 3 years now. I have put more money into it than I paid for it. It’s crazy. Pros: I can control it with an app on my phone via WiFi. It is pretty quiet. Cons: Even with the above two items if the system isn’t cooling and heating properly then it is not reliable and makes the two pros null and void in my opinion. This system has only worked correctly for one, maybe two seasons. I can’t keep calling the HVAC company to come look at this thing. I clean the filters regularly. At this point, I am going to scrap it and just use an electric heater and a portable AC unit. Those seem to be working fine for me. Yes, I had to invest in other items to heat and cool my small space. I will say the company refunded me some of the money I paid the first time I had it repaired. But come on! Spend the extra money and get a more reliable brand and hopefully, a more reliable system.

Shipped fast, arrived way before expected. Was a simple install, need a vacuum pump though. Seems to work good. Most the time it seems to be running at about 300 watts. Puts out a lot of heat at about freezing temps. AC was measured at 18° at the inside evaporator. Remote is nice. Runs very quiet. App doesn't show electricity use though, bummer. Will update with some use.

Works perfect i put it in a new build 12x14 and kt cools it perfectly
