Why did you pick this product vs others?:My unit ia 23 SEER which is better than most.Air quality:Works fantastic. Helps me sleep at night by keeping my bedroom cold without having to cool the whole house so cold. Saves a lot on my electric bill.Build quality:Excellent and was easy to self install.Cooling ability:Cold, cold, cold! Love it.Remote control:Remote could be better. The display is too small for poor old eyes. The all on my phone is much better to control it but it occasionally gets unpaired and is difficult to reconnect. Also could use controls on the unit so you can still operate it if the remote breaks or is lost.Noise level:Is extremely quiet!

I’ve had mine for about 6 months now and it is still keeping my gym cool in the summer and warm in the winter.The indoor unit is efficient, sleek, and quiet. The outdoor unit is not bulky and is relatively quiet in both heat and cool modes. They give you plenty of lineset for residential use. Everything was very simple to install and set up.Originally when I got this unit, it did not work. I was sent a defective unit, however the Della customer support sent me replacement parts needed free of charge and quickly.

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.

I've installed (3) of these units on my 1,400 sf house plus (1) on a 350 sf garage in Florida and they have completely replaced my central air system and gas furnace. My central air system was 3.5 ton cooling capacity and I replaced that with (1) x 1 ton DELLA in the great room and (2) x 0.75 ton DELLA units in the two bedrooms. I installed the 4th 1 ton unit on the garage. The total 2.5 ton capacity of the DELLA units in the house has been more than enough capacity to cool and heat my home as effectively as the old central air could. I had no installation issues and all four units are performing well. I do have a list of minor complaints to offer.1) Most of the units came with some small dents or damage to the outdoor unit. Mostly depressions on the top of the metal housing that cause rain water to collect. All of the head units had a bent air louver due to it being packed up against the electrical cabling that's in the box.2) All of the units are reading almost 3 degrees higher than the actual room temperature. Not an issue once you know this but seems strange that they are not calibrated correctly.3) If you control the units with both the app and the remote there are annoying sync issues. For example, if you've set the display and sounds to be off in the app, and then want to adjust the temperature via remote, the display and sound return to default on rather than how you had them set. This gets really annoying if you want to have a dark bedroom at night and use the remote to control the unit rather than the app.4) Within the Scenes programming in the app, there is no option to set the units in "eco" power mode.5) All of the units occasionally lose connection with wifi and have to be reset by the breaker to reconnect.Besides these minor annoyances, I'd highly recommend these considering their low cost and high energy efficiency. I'm now using almost 1/3 the energy to cool my home that my central air system was and with an installation cost that was also far lower. The ability to control each rooms temperature independently and even direct the airflow directly from your phone are things you will wonder how you ever lived without.If you live in a house with central air ducting running through an attic or other uninsulated space you will likely see huge efficiency gains by eliminating your central AC as I have by moving to all ductless systems. These units are a cost effective way to do that for someone with moderate DIY skills.
