DELLA Umbra Series 18000 BTU Energy Saving Mini Split Work with Alexa 19 SEER2 Cools Up to 1000 Sq.Ft Split AC & 1.5 Ton Heat Pump Ductless Pre-Charged Inverter System

The condenser (outside) unit is pre-charged; however, the copper lines and top unit (Inside) are not. After connecting the lines, a vacuum must be pulled and tested for leaks. you can rent the install kit from DELLA or purchase this at Harbor Freight and Amazon. It is fairly easy to install but must create a large hole from inside to outside to route the power and freon lines. I installed the unit but hired an HVAC company to pull the vacuum to set the freon. this unit does cool my 550 sqft enclosed porch and works with phone app as well as Alexa. It is very quiet and sounds like a fan running.

I installed the unit just in time for the bitter cold we had in the Northeast last January. It kept my house warm and cozy throughout the coldest winter days. Installation was a breeze for me because I’ve installed a few mini splits over the years. Word of caution for DIYers, take your time with it and don’t kink the lines, make sure to thread the lines very carefully and follow the instructions provided with the unit or you’ll be back here writing a negative review about the unit that it doesn’t deserve. It’s a great value for the money and a great addition to any space when installed properly.

Put your coat on!! I like the room cold when I sleep. It’s summer in Florida right now and I am using TWO comforters! Love this split unit!!! No leakage. We installed it ourselves so we saved on the installation. Awesome value!

The Della heats and cools efficiently for our space as needed. A drawback was that that the installation did not go smoothly. We had it installed by a handyman who had it up and running but it would not cool. It had to be evacuated and that required an HVAC guy. I had trouble finding one to work on this unit because it is not typical for the East Coast.

HOLY COW!!! SERIOUSLY!!! Never in my wildest dreams did I think the mounting bracket for this 12000btu indoor unit would be less than 16"(on center) wide! Leave it to the wonderful folks at Della to cut the most random corner of all time. This unit didn't ship with a mounting bracket wide enough for 97.3% of all American homes!! Even the poorest made Ryan homes have studies that 16" On Center...yet my Della mounting bracket isn't capable! Line set that is too short, sure. Plastic blower fan, okay. Not being able to mount the indoor unit on two studs...MIND BLOWING! Now I have to repack LITERALLY everything and return 100% of it! Thanks a lot Della!

I have had these for a year and half now with no problems. Low utility bills. Run extremely quiet. Keeps the area extremely cooled at 72 and warm in the winter. No need for alternative heating and cooling. Installation was extremely easy and easy to follow instructions.

Easy to install. DIY. Quiet. Looks great. Heats and cools with ease. Comprehensive remote. I will be installing another, soon Excellant value, superior performance

This was best investment I've ever made. I put this on the wall on my porch that I've converted to a sun room. This extra space that I enclosed with plexiglass and wood and sealed with insulation stayed about 20 degrees different from out side. With a window unit and heaters. Now with the split unit it stays what ever temp I want it to be. The della split unit is so quite I have to put my ear on it to hear it run sometimes the out side unit is even quite. If you mount on outside wall that is a little thin and only a few inches thick it might give a little bit of a hum but so slight you have to want to hear it. Turbo cool or heat will cool or heat super fast. The remote is confusing really bad even with the instructions. No real video to watch on it and you can not out it on auto and set a temp. When you put it on auto which is what I use the most your temp is not settable. You can NOT set auto. Not even on the app. AUTO can not be set. I have not found anything anywhere that can tell me how to set auto. Otherwise this is perfect 👌 👍 🥰. I love it.
