    • Great, heat pump and customer service BUT! I learned an imporatant detail required when wiring
Size: 12,000 BTU - 230V / 21 SEER2 - WIFI Style: QC Series Product Packaging: Standard Packaging
Headliner - I am very impressed with the value and performance of this unit so far, after about 1 month of use in VERY cold conditions. Detail about the unit it's self - So this Della is produced by Midea, like many others, it is very similar to units like the Pioneer brand which is also a Midea product; but not identical with small differences such as the remote control and the APP. Upon contacting Della for support, I was provided with "manufacturer's documentation" that was branded "AUX", another brand commonly sold on Amazon and other retailers; I have no issue with this, it's just an observation. Tip I learned for successful installation- Let me start with the tip I learned first, to help others avoid this installer error. When I first installed the unit it immediately went into error mode after about 30-60 when trying to heat; it displayed a code of (I think this was the code) "E5" as I recall. I installed other heat pumps before, I am an experienced builder and have an electronics background yet I still missed on this detail! Here's the catch, I had inadvertently swapped L1 and L2 wires between the indoor and outdoor units; thinking they are both "HOT", I had not paid enough attention to insure it was L1 to L1 and L2 to L2. On dumn appliances like an oven, dryer, or water heater, this does not matter and I had just finished wiring all of those and had that mindset stuck in my head. I knew I had the hot/load wires connected to the Load terminals, but did not realize the phase would matter. When these were incorrectly paired, the unit turned on and was fully responsive but would go into error when trying to heat. After correcting this, the issue was immediately resolved. I also used a Square-D SDSA1175 surge suppressor at the disconnect box on all my heat pump installations; it seems that many heat pump issues are related to failed control boards, it is my theory that a surge suppressor is mandatory for a heat pump. Regarding customer support- I reached out to customer support and immediately got a human on the phone who spoke perfect English (a bonus for me as I only speak English). While this rep was not a trained technician, they were very responsive to my needs, understanding of the issue, and emailed me several technical documents which went much deeper into detail than what was provided with the heat pump. The next step if these documents were not successful would have been to put me in contact with their technician but, using the documents led me to the discovery of my error in swapping L1/L2 between the indoor and outdoor units. Upon correcting that, the error code never re-appeared, and the unit began blasting heat! So kudos to the tech support and a notch in my humility belt as this was my error. All-in, tech support helped me resolve the issue I induced within a a few hours' time. I did recommend that they document and flag for future customer support issues with E5 to immediately suggest checking the L1/L2 wires between IDU and ODU. Which unit I bought and Install details - I bought the 1-Ton / 12k BTU for a 725sqft basement remodel that is a daylight basement with 3 concrete sides; The area is very well insulated. I also bought the 240v R32 model. I was a bit hesitant of this newer gas as my local HVAC resources are not familiar with it. Installation was the same as the other heat pumps I've installed, a bit of a pain to connect the copper lines to the back of the indoor unit due to being mounted on a stud wall that was up against a concrete wall so the copper lines had to be rather custom bent to go into the stud-wall, up and over the concrete wall but I was successful on first attempt simply using a cheap $20 bender commonly available on Amazon. I used the stock flares that came pre-flared on the ends of the pipes too, no thread sealer, and did torque to the recommended settings. I pulled a vacuum using a micro gauge; it got down to about 400 after several hours and after a few hours of sitting it remained below 500 so I called that good and opened the valves. How well it works- Very well! A 1-ton is only rated for about 450-500sqft and I am successfully using this in about 725sqft, two areas separated by a hallway. The unit points into the hallway which is helpful in pushing air into the secondary area which granted is not quite as warm but is very satisfactory. And this area is recently and very well insulated which is a bonus. The unit is extremely quite both indoor and out. I installed this in the winter of 2023, it was about 50 degrees in the pacific northwest; it was able to bring the whole 750 sqft up to about 68-70 in very short order, a few hours, which is exceptional in my opinion as the area was cold soaked for weeks. Since then, the temps have dropped to record lows here of 5 degrees F. We really did not notice any difference in the operation and performance of this DELLA, we just left the settings at 68-70 and it kept the area 68-70. I have a Daiken 18000BTU for the upstairs area which is closer to 1300sqft and not nearly as well insulated; that unit typically is sufficient for the space but in these record lows, it had issues remaining running with the cold temps and did some short cycling. Features- This Della has an excellent set of features. I really like the independently selectable vertical and horizontal louver swing that can be controlled from the remote. The remote also has an option to toggle between the setpoint and the actual measured temperature at the remote; a feature our Daiken does not have. It came with WiFi built in (another feature our Daikin does not have) and it came with an App. The App unfortunate is only useful for basic operation, this is probably the least exciting aspect of this purchase. The app has a scheduler, but it can only turn the unit on or off... Really? It does not have goe-fencing or any other common features I'd expect as these are commonly available this day in age. If more modern remote control is needed, I will go with something like the Cielo Breeze (I use that on the Daikin, while its powerful it still is complicated and a bit unintuitive). From the remote, there are several other power user options like self clean, sleep temporary timer, a on/off timer; I like the remote! The fan speed is selectable although we leave it on Auto and it is very quiet. I like the LED display on the front of the unit as well, this can also be toggled on/off from the remote Longevity- I've only had this up and running for a bit over a month, no issues at this point. So, that's not the most useful data point. I have had the top off the external unit to "have a look" it looked well built. Summary - I'd never heard of DELLA before this but I get it, DELLA is a brand, selling a slightly customized Midea heat pump like many other companies. So far, my experience has been exceptional in all regards from performance to value, to customer services. I am one to gable on things like this, at $625 the risk was well worth it for me. This was no harder to install than any other similar unit and didn't have any "unusual" quirks like abnormal threads... At this time I would not hesitate to buy another one of these. ... show more

    • best bang for the money
Works great in Houston TX. Using it for 6 months, heats and cools 600sqft of open space nicely. DIY install is very easy. Do not hook up the copper pipes and let the refrigerant run without a proper vacuum to under 300 microns and you won't have a problem. My outside unit bas banged up during shipping and Della gave me a 30% discount which is great. Saved $250 by a little dent which is not even visible. App works ok, not being able to change auto temp sucks. We like to keep the room at 70F and auto temp is set to 75F that's only down side. ... show more

Save a lot of $$$ and do it yourself! If I can do it so can you! Watch some videos and take your time. Instructions are fairly vague, but it's a simple process. Follow the vacuum down instructions for the line set (I bought a vacuum pump and gauges from VEVOR for $105) and don't be in a hurry. Works great and is fairly quiet. Definitely recommend. ... show more

    • Ok for small rooms
Update: Can this be a ZERO star! 13 months and now the unit no longer works. It gets power everywhere. Except for the indoor unit will not turn on, even the display will not light up. Enough said. First the cons. This mini split unit is not strong enough for a 400 square foot room. Left on for 36 hours straight and only lowered the temperature by 2 degrees. Room is 20ft x 20ft with ceiling @ 8ft high. So room went from 86F to 84F. Lineset is only 10ft, wish it would have been in the description. Lineset sizes are not correctly listed on the lines, 1/4" copper line is fine, but the one labeled as 1/2" is only a 3/8" copper line. Outdoor unit will only accept the 1/4" and 3/8" linesets. Other units from different manufacturers are 16ft. Had to order a 16ft lineset. Would have just sent this mini split unit back, but from other reviews, they were having to pay to ship back. No real instructions, especially on the wiring location for the indoor unit. Wiring is behind the aluminum panel thats behind the front plastic cover on the front, right side of the unit. The outdoor unit electric panel at least gives you the wiring diagram, so this could be followed to connect the indoor unit. No manual, so don't know what all the buttons on the remote are for. No side to side swing for the vent. Up and down swing isn't smooth operating, has a slight stutter in it several times. Had a bent rear right foot on unit. Exposed fins on the left side of unit were bent at the top. There is no protective screen or anything for the left side. The fins are just exposed. Pros: Unit does blow cold on cold setting, hot on heat, fan mode works, humidifier works. ... show more

It was easy to install. If you know basic wiring you can do the job yourself and save money. It's quiet and works very good. Only set back is that I didn't notice the refrigerant lines were only 9 foot long. Put a damper on placement of the condenser. And you have to pay more for an extension. Will look at other manufacturers next time. But works good. Did not come with template for me either for hanging on the wall. ... show more

I bought the 18,000 btu-model and installed it myself for a garage, I do have some experience with ac and the kit they include had most parts you’ll need. I purged the lines with Kwik-E-Vac line set flush and used Nylog Blue on my flare fittings. Budget about $300.00 for wall hanger, line set cover & wire etc. Connection to Wi-Fi was ez. It’s not the same quality of a major named brand but it’s about 1/2 the price. Great communication with the company. I’m 100% pleased ... show more
