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

I purchased this mini split system last summer. The quality is great and with a little DIY research, easy to install. I had a self-induced problem programming the system to use the Android app, and tech support was fast and easily remedied my problem. It cools about 1000 sq ft in 90 deg f weather for us. Works down to 20 deg F for heating in the winter

DIY install. You should use a heat pump to prep the lines for install. Ours has been installed for 2 summer and 1 winter. Works great. App is much better than the remote for controlling the unit. Be careful not to kink the lines.

I'll give this unit 4 stars for the quick shipping and well package items. I installed the 220v 18k black unit in my 40ft 5th wheel so that I wouldn't need to run any of the 3 roof mounted units during the summer. I have installed these units before, so installation was straight forward. It did come with clear instructions which fell in line with how these units are typically installed. It's on it's own disconnect at the service panel which makes it run separately without robbing the trailer of it's own supply. The only issue I have is the temperature settings to maintain my desired room temperature. Regardless if I use the app or the remote, in order to keep a temperature of 70 degrees in heat mode, I need to set the unit to 75. If I set it to 70, it will heat the space to 75 degrees or more before the fan slows to a crawl. Living in Arizona, I have had a few days to try out the AC side of this. Same issue. Except I need to set the unit to 86 or higher to maintain a room temperature of 80 or it will freeze me out. I've checked the app, and it states the room temp is 78, with the unit set to 84, and still blows cold. Setting the fan mode to "auto" keeps the fan blowing at speed 1 during AC, where during heat mode, it would lowered to a silent crawl. Once I feel comfortable, I need to change the fan to "quiet" during AC just to keep the room from getting colder. I do appreciate the ability to control this unit from anywhere concidering I travel a lot. Only one time did it have a glitch where it wouldn't respond, so I just reset the breaker.

I bought my mini split to help cool my garage come the summer heat. When I first set it up it worked great - but it was only 80 degrees outside. Now that we are in the 90s the unit has stopped cooling completely and throws an error every time. I looked up the error and per the manual it only occurs when it’s too hot outside. Like seriously, what’s the point of a mini split for cooling if it stops working in the 90s. I have tried contacting the manufacturer via their app, website and Amazon and have not heard back. I wouldn’t recommend this unit to anyone.

Great price for proposed function had not had the time to install this in my office but plan too soon and will update when possible.

As mini splits go, this one doesn't suck. First black one I've ever installed. Nice for the commercial application but I wouldn't want it for my home. Great deal though!

I bought this mini spilt because of the price to cool my 35 foot 5th wheel. Living in Arizona during the summer, I needed an a/c that wouldn't cost me a fortune to operate. Both my overhead units were costing me as much as $399 A month. The first month using this mini spilt cost me $114. The customer ratings on this brand (Della) was mostly good, so I took the chance on it. I put the unit in myself with no problems. I did need to have our park matenence man wire it into the meter box and vacuum the lines. I placed the unit on the rear wall of the trailer to blow back to front and it's doing a great job. Depending on the day (how hot it is) I run it at 78-80° and pretty cold in the back of the trailer and keeps the front bedroom comfortable. I am very pleased with the purchase of this unit and brand.

Was worried at first due to it being a brand I'm not familiar with, but it works extremely well. Make sure you get an HVAC professional to flail out the ends for flush fittings. Also get the 3 year warranty jic. Edit: You will have to purchase wire sleeve and holding bracket separately.
