What a fun project challenge that I am glad I undertook. ***This is not an installation for those who are not mechanically inclined*** However, I have done major renovations on several of my residences over the years and had the cahones to take the leap into what I previously considered to be a magical realm.You will need a vaccum pump, R410A adapter, pressure gauge rig (comes with pump), and I really advise a torque wrench with adjustable wrench head (unless you're sure you have the flare nut sockets needed for the lineset diameters of your system). Overall, ~$170 for these if you don't have them already (pricing as of ~Dec'24) I also got Nylog Blue... not sure if I needed it, but it didn't hurt.I did a relatively unconventional installation in that I routed a 25' lineset from the left side of the unit, flush with the wall. My condensate line was also run on a slightly sloped horizontal run indoors, then diverted outside. (I installed this in a finished portion of the basement that allowed me to run the lines through a wall and along an unfinished interior wall of an adjacent area).Caution: if you are using a wall-mount bracket for the outside unit, know that, even with thick rubber vibration damping feet, the compressore section will telegraph a low intensity hum/vibration through the wall studs to the interior space. this is interesting, since there is extremely quiet operation of the unit outdoors otherwise. in my case, the hum was in the unfinished space, thus not relevant. if you will install against a wall in a finished space, I recommend a ground slab mount (on a raised mount if you're in snowfall country).I haven't gotten the app/wifi function running yet, but the hand remote is great. The unit takes a minute or two to fire up and equilibrate, so don't expect it to turn on a dime when you switch modes or temperatures. but, it runs essentially as quietly as the Mitsusbishi units that I had professionally installed at one of my former homes.Wishes: there does not appear to be a setting in which the fan periodically circulates air to mix the air in the room and keep it uniformly conditioned. Since I have high ceilings, and I needed to mount this at about 8 feet up, the air is stratified and is at a different temperature up higher than the rest of the room at 'living' levels (~3-6 feet up). There is a fan-only setting, but this is not in heat or cool mode.I found customer support through the chat remarkably responsive and effective. There is no other way to get in touch with the company. But, rest assured, THEY ARE THERE and respond within a minute or two. All questions were answered quickly and effectively. Where I found an error in the manual that led me to order the wrong diameter lineset, they quickly refunded me so I could buy the right one. (on this note, it would be more convenient and less wasteful to allow the customer to pick the right lineset length when ordering. in the end, I was left with the original 16 foot lineset that came with the unit. (note: the unit comes pre-charged wth enough refrigerant for a 25 foot lineset!)I should also note that there was a small dent in the outdoor unit base due to shipping damage. Look like a forklift might have pierced the box. It was cosmetic only and didn't impact the function of the unit. And, it turned out that my installation location has it largely hidden from plain sight.So, now it's up to seeing how durable the unit is. Otherwise, I would TOTALLY buy another of these when I come across another project like this.

I bought two of these units and installed them myself. I followed the instructions and took my time. Everything came together neatly and my wife says it looks like a professional installation. It cools the room nicely. Our bedroom gets warmer than the rest of the house and this really helps at night. I'm hoping it will hold up to the summer heat in Phoenix but only time will tell. So far I'm extremely satisfied with this product and if it only works for even 5 years it would be worth it to me. Hopefully it will last longer. It's pretty quiet. I mounted the outside unit on the wall and you can hear it a little when you turn down the temperature and it has to really start working but generally I don't hear anything. When I turn the unit off, I'll hear some noises like rattling in the wall but that came after I used spray foam insulation to fill the hole inside the wall. I was quoted almost 10k dollars to install 2 of these and a bigger one for the living room. I didn't install a bigger one in my living room but installed 2 of these in bedrooms and it was asking 2k including the electrical, wall mount, line set cover, hole saw, vacuum pump, and all the other necessary tools and stuff that I didn't have. I would definitely recommend this. It even works with my Google home app and I can change the temperature by asking Google which is a nice touch.

Bottom line, I’m happy. I bought the 12K BTU, 115V, 22 SEER unit for a 300 square foot in-law suite. I installed it myself. It was not difficult, but I’m also someone who can be considered a handyman. I watched a lot of videos on how to install mini-splits. You’ll have to buy some special tools which will run you about $150, unless you can borrow them. However, Della now offers an installation rental kit for $100. They send you the tools to use, and you send them back, primarily a vacuum pump and gauges. So far, I’ve used the AC and heat, and both work great. The two packages arrived fast and un-damaged. I ran my own 20 amp, 120V circuit to the unit. It’s quiet, both inside and outside. If there is one thing I had to mention I didn’t care for, that would be the remote. It works, but I wish they had just kept it simple. I don’t care for fancy bells and whistles on products. Just give me 5 functions; Heat, Cool, Temperature, Fan speed, and maybe an Auto option. I don’t need WiFi, and Alexa, and 30 different settings, and timers, etc. Keep it simple! Also, I’d prefer it if the display on the remote had text instead of icons. I’d rather read “Heat” or “Cool”, instead of seeing an icon of a sun and snowflake, which are tiny, and both look similar on the screen. I can live with it but wish they would offer a simpler controller. All and all, good value here.
